Approximately 15.87% of the bowlers in the Capital Three bowling tournament performed better than Dr. Baker.

How to find the proportion

Standard deviation (σ) = √(variance) = √(121) = 11

Now, we can calculate the z-score for Dr. Baker's average of 169 using the formula:

z = (X - μ) / σ

z = (169 - 158) / 11

z = 11 / 11

z = 1

Dr. Baker's z-score is 1, meaning his performance is one standard deviation above the mean.

The area to the left (or the cumulative probability) is approximately 0.8413

1 - 0.8413 = 0.1587

The statement, "t is not less than 7" as an inequality is E. t ≥ 7.

The statement, " the negative of z is not greater than 8" is A. - z ≤ 8 .

How to represent as inequalities ?

The statement "t is not less than 7" means that t can be equal to 7 or greater than 7, so we can write this as:

t ≥ 7

Therefore, the correct inequality for the statement is t ≥ 7.

Similarly, the statement "the negative of z is not greater than 8" means that the opposite of z, which is -z, can be equal to -8 or less than -8, so we can write this as:

-z ≤ 8

Multiplying both sides of the inequality by -1 gives:

z ≥ -8

Therefore, the correct inequality for the statement is z ≥ -8.

Answer:

e) The correct option is: t≥7

The phrase "t is not less than 7" means that t can be equal to 7 or any value greater than 7, but it cannot be less than 7. Therefore, we use the greater than or equal to a symbol (≥) to represent this statement.

here's an explanation of each option:

t = 7: This statement indicates that the value of t is exactly 7. If this statement is true, then t cannot be greater than or less than 7.t > 7: This statement indicates that the value of t is greater than 7. If this statement is true, then t can be any value that is greater than 7.t < 7: This statement indicates that the value of t is less than 7. If this statement is true, then t can be any value that is less than 7.t ≤ 7: This statement indicates that the value of t cannot be greater than 7, but it can be less than or equal to 7. If this statement is true, then t can be 7 or any value less than 7.t ≥ 7: This statement indicates that the value of t cannot be less than 7, but it can be greater than or equal to 7. If this statement is true, then t can be 7 or any value greater than 7.To express the statement t≥7 as an inequality in terms of 7a^2, we can simply multiply both sides by 7a^2, like this:

t * 7a^2 ≥ 7 * 7a^2

Simplifying the right-hand side of the inequality, we get:

49a^2

Therefore, the inequality in terms of 7a^2 is:

t * 7a^2 ≥ 49a^2

Note that this inequality is equivalent to t ≥ 7, which is what we started with.

f) The correct option is:-z ≤ 8

The phrase "the negative of z is not greater than 8" means that -z cannot be greater than 8. In other words, -z is less than or equal to 8. To express this as an inequality, we use the less than or equal symbol (≤) and write "-z ≤ 8".
here's an explanation of each option:

-z ≤ 8: This statement indicates that the negative of z is less than or equal to 8. If this statement is true, then -z can be any value less than or equal to 8.z ≤ 8: This statement indicates that z is less than or equal to 8. If this statement is true, then z can be any value less than or equal to 8.z < 8: This statement indicates that z is less than 8. If this statement is true, then z can be any value less than 8.z ≤ -8: This statement indicates that z is less than or equal to -8. If this statement is true, then z can be any value less than or equal to -8.-z < 8: This statement indicates that the negative of z is less than 8. If this statement is true, then -z can be any value less than 8.

Note that only the first option (-z ≤ 8) accurately represents the original statement "The negative of z is not greater than 8". The other options either represent a different statement or contradict the original statement.

The statement "the negative of z is not greater than 8" can be expressed as an inequality in terms of 7a^2 as follows:

-z ≤ 8

Since we cannot multiply or divide by a negative number when we are working with inequalities, we will multiply both sides of the inequality by -1. Remember that whenever we multiply or divide both sides of an inequality by a negative number, we must reverse the direction of the inequality symbol. So, we have:

z ≥ -8

Multiplying both sides by 7a^2, we get:

7a^2 * z ≥ -8 * 7a^2

Simplifying the right-hand side, we get:

-56a^2

Therefore, the inequality in terms of 7a^2 is:

7a^2 * z ≥ -56a^2

So, the statement "the negative of z is not greater than 8" can be expressed as the inequality 7a^2 * z ≥ -56a^2.

Answer:2.86.

Step-by-step explanation:

We can use the geometric distribution to solve this problem. The geometric distribution models the number of trials needed to achieve the first success in a sequence of independent trials with a constant probability of success.In this case, the probability of success (the teacher tripping over the cords) is 0.35. Therefore, the expected value or mean of the geometric distribution is 1/0.35 ≈ 2.86.So, on average, students need to wait for 2.86 periods until the teacher trips over the cords in her classroom.Therefore, the answer is 2.86.

Answer:

  2. 139π/90 radians ≈ 4.852

  3. -(9√5 +8√7)/77

  4. 2+√3

Step-by-step explanation:

You want exact answers involving various trig identities and angle sum formulas.

2. Radians

There are π radians in 180°, the number of radians in 278° is ...

  278°(π/180°) = (278/180)π

  278° = (139/90)π radians ≈ 4.852 radians

3. Cosine

The cosine of the sum of angles is ...

  cos(x +y) = cos(x)cos(y) -sin(x)sin(y)

The relationship between sine and cosine is ...

  cos(x) = ±√(1 -sin(x)²)

  sin(x) = ±√(1 -cos(x)²)

The signs will depend on the quadrant of the angle.

To use the angle sum relation, we need the sine of the angle whose cosine is given, and vice versa.

  sin(arccos(-2/7)) = -√(1 -(-2/7)²) = -(√45)/7 = (-3/7)√5 . . . . in QIII

  cos(arcsin(-3/11)) = √(1 -(-3/11)²) = (√112)/11 = (4/11)√7 . . . . in QIV

The cosine of the sum of the angles is then ...

  cos(arccos(-2/7) +arcsin(-3/11)) = (-2/7)(4√7/11) -(-3√5)/7·(-3/11)

  = -8√7/77 -9√5/77

  cos(x +y) = -(9√5 +8√7)/77

4.  Tangent

The formula for the tangent of the sum of angles is ...

  tan(x +y) = (tan(x) +tan(y))/(1 -tan(x)tan(y))

We know that tan(π/4) = 1 and tan(π/6) = 1/√3, so the tangent of the sum of the angles is ...

  tan(π/4 +π/6) = (1 +1/√3)/(1 -(1·1/√3)) = (√3 +1)/(√3 -1) = (√3 +1)²/2

  tan(π/4 +π/6) = 2 +√3

4) the exact value of the expression is 3.73

How is this so ?

The formula ofr conversion from degree to radian is

2) 278° × π/180 = 4.852rad

3) in the above given expressions, Sin(x) is negative.

Using Pythagorean rule, we can state:

sin(x ) = √(1 - cos^2(x)) =

√(1 - (-2/7)²)

= -3√(3)/7

Also,

given that cos( y) is positive, we c  n also use the Pythagorean idetity

cos  (y) = √(1 - sin ²(y) )

= √(1 - (-3/1 1)²)

= 8√(2)/11

substituting into cos (x + y)


cos(x+y) = cos(  x)cos (y ) - sin (x) sin(y)

= (-2/7)( 8 √(2)/11) - (-3√(3)/7) ( -3/11)

= -1 6 √(2) /77 + 9√( 3)/ 77

= -0.09141506142

The exact value is approximately -0.0914

3)

Using the formula for tangent of sum of angles we say

tan( ( π/4) + (π/6) )   = (tan ( π / 4) + tan (π/6))/(1 - tan ( π/4) tan( π/6))

Sutstituting ....

tan ((  π/4) + ( π/6) )  = (1 + √ 3/3)/( 1 - √ 3 /3 )

tan( (π/ 4) + (π /6 )) =   (1 + √3/   3) (1 + √3/3 )]/ [(1 - √3/ 3)(1 + √3/3)]

Simplifying

  tan ( (π /4) + ( π/6) ) = ( 2 + √3 )/  ( 2 - √ 3)

This is the exact value of tan((π/4) + (π/6)) or 3.73

The relative change from 1995 to 2000 is -63.92%, indicating a decrease in price of approximately 63.92%.

How to calculate the relative change?

To calculate the relative change from 1995 to 2000, we need to find the difference between the prices in those two years, and then express that difference as a percentage of the price in 1995.

Price in 1995 = $351.94

Price in 2000 = $349.69

Difference = Price in 2000 - Price in 1995

Difference = $349.69 - $351.94

Difference = -$2.25

The negative sign indicates a decrease in price from 1995 to 2000.

Now, we can calculate the relative change as a percentage:

Relative change = (Difference / Price in 1995) * 100

Relative change = (-$2.25 / $351.94) * 100

Relative change = -0.6392 * 100

Relative change = -63.92%

Therefore, the relative change from 1995 to 2000 is -63.92%, indicating a decrease in price of approximately 63.92%.

The area of each triangle to the nearest square inch is approximately 95 square inches.

What is triangle?

A triangle is a 2-dimensional geometric shape that consists of three straight sides and three angles. It is one of the basic shapes in geometry, and it is widely used in various fields such as mathematics, engineering, architecture, and art.

According to given information:

To find the area of an equilateral triangle with a radius of 12.7 inches, we can use the formula:

Area = [tex](\sqrt{(3)/4})[/tex] x [tex](side)^2[/tex]

where side is the length of one of the sides of the equilateral triangle.

We know that the radius of the equilateral triangle is 12.7 inches, which means that the distance from the center of the triangle to one of the corners (i.e., the length of one of the sides) is also 12.7 inches. To find the length of the side, we can use the formula for the height of an equilateral triangle:

and solve for side:

side = Height / ([tex]\sqrt{(3)/2[/tex]) = (2 x Height) / [tex]\sqrt{(3)[/tex]

Plugging in the value of the radius, we have:

side = (2 x 12.7 inches) / [tex]\sqrt{(3)[/tex] ≈ 14.67 inches

Now we can use the formula for the area of an equilateral triangle:

Area = ([tex]\sqrt{(3)/4}[/tex]) x [tex](side)^2[/tex]

Plugging in the value of the side, we have:

Area = ([tex]\sqrt{(3)/4[/tex]) x [tex](14.67 inches)^2[/tex] ≈ 94.71 square inches

Therefore, the area of each triangle to the nearest square inch is approximately 95 square inches.

If Joan has a square flower bed with a side length of 4 meters filled with tulips, the density of tulips in the bed is 22.1 tulips per square meter.

To find the density of tulips for the area of the bed, we need to divide the total number of tulips by the area of the bed. The area of the square flower bed is the side length squared, so in this case, it is 4 meters x 4 meters = 16 square meters.

So, the density of tulips in the bed is 354/16 ≈ 22.1 tulips per square meter. This means that there are approximately 22.1 tulips growing in every square meter of the flower bed.

The density is a measure of the amount of something per unit of space, so in this case, it is the number of tulips per square meter. It is a useful metric for understanding how many of something is present in a given area, which can be important for planning and management purposes.
