The probability that the call center will get fewer calls than 440 is 0.26115.

Given mean of 4900 and standard deviation of 700.

We have to calculate the probability that the call center will get fewer than 4400 calls.

Probability lies between 0 and 1.

μ=4900

σ=700

We can  apply z as well as t statistics because the sample size is not given.

We are applying z statistics.

P(X<4400)=0.5-P(4400<X<4900)

z=X-μ/σ

where μ= mean

σ=standard deviation

z=4400-4900/700

=-500/700

=-0.71

p value of -0.71 is 0.23885.

So the p value of calls less than 4400 is 0.5-0.23885=0.26115.

Hence the probability that the call center will get calls less than 440 is 0.26115.

We cannot reject the null hypothesis as the p value is less than 0.01.

From the information given, Luiza wants to go on a popular talent TV show and in order to be accepted, her audition must get at least 60% positive votes from the people in the crowd.

The observed outcome also has a probability less than 1% under the tested hypothesis. Based on the information, the test statistic will be - 1.58.

After this, this will be checked under the standard normal distribution table where the p value will be 0.0571.

Based on this information, we cannot reject the null hypothesis as the p value is less than 0.01.

In conclusion, the correct option is that we cannot reject the hypothesis.

Answer:

can you tell me please

Step-by-step explanation:

nicest

The measure of angle C is obtained as 35 degrees

Give that;

b^2 = a^2 + c^2 - 2ac Cos B

a = 29

c = 24

B = 101 degrees

b^2 = (29)^2 + (24)^2 - [2 * 29 * 24 cos 101]

b^2 = 841 + 576 + 266

b = 41 cm

Now;

b/sinB = c/sinC

bsinC = csinB

sinC = csinB/b

sinC =  24 * sin 101/41

C = sin-1(24 * sin 101/41)

Step-by-step explanation:

using the Cosine Rule in the triangle

cosΘ = [tex]\frac{80^2+60^2-70^2}{2(80)(60)}[/tex] = [tex]\frac{64000+3600-4900}{9600}[/tex] = [tex]\frac{5100}{9600}[/tex] = [tex]\frac{51}{96}[/tex] , then

The initial value is 37,036 dollars and in 4 years, the value will be 18,439.16 dollars.

Here we have an exponential decay that models the value of a car as time passes, the exponential decay is:

[tex]v(t) = 37,036*(0.84)^t[/tex]

The initial value is what we get when we evaluate in t = 0.

[tex]v(0) = 37,036*(0.84)^0 = 37,036[/tex]

The initial value is 37,036 dollars.

The value in 4 years is what we get when we evaluate in t = 4:

[tex]v(4) = 37,036*(0.84)^4 = 18,439.16[/tex]

In 4 years, the value will be 18,439.16 dollars.

Hello,

[tex] \frac{5}{4 - m} = \frac{ - 3}{2 + m} [/tex]

[tex]5(2 + m) = - 3(4 - m)[/tex]

[tex]10 + 5m = - 12 + 3m[/tex]

[tex]5m - 3m = - 12 - 10[/tex]

[tex]2m = - 22[/tex]

[tex]m = \frac{ - 22}{2} [/tex]

[tex]m = - 11[/tex]

→ Answer B

Variable m cannot be equal to any of the values −2,4 as division by zero is undefined. Multiply both sides of the equation by (m − 4)(m + 2), the lowest common denominator of 4−m,m + 2.

To find the opposite of 2+m, find the opposite of each term.

Use the distributive property to multiply −2−m by 5.

Use the distributive property to multiply m−4 by −3.

Add 3m to both sides.

Combine −5m and 3m to get −2m.

Add 10 to both sides.

Add 12 and 10 to get 2.

Divide both sides by −2.

Divide 22 by −2 to get −11.

Therefore, the correct option is "B".

Answer:

12 / (2+1) + 6 * 2 = 16 (The answer is 16)

Step-by-step explanation:

Step 1: Calculate within parentheses ( 2 + 1 ) : 3

Step 2: Multiply and divide (left to right) 12/3 : 4

= 4 + 6 * 2

Step 3: Multiply and divide (left to right) 6 * 2 : 12

= 4 + 12

Step 4: Add and subtract (left to right) 4 + 12 : 16

The surface area of the prism is 544 mm²

The formula is given thus;

SA=2B+ph

B = area of the base

p = perimeter of the base

h = height

B = 1/2 h(b1+b2)

B = [tex]\frac{1}{2} * 8 * (17 + 9)[/tex]

B = 108 mm²

Perimeter = sum of length of sides

Perimeter = 17 + 9 + 15

Perimeter = 41 mm

Surface area = 2 ( 108 ) + 41 ( 8)

Surface area = 216 + 328
