When two companies have a correlation value of -0.95, there is less than zero covariance between their returns. So statement d is correct.
The correlation coefficient is an important measure that helps to establish a relationship between two variables. Its value is mostly between +1 to -1. Therefore, the value can be positive, negative, or zero. Based on this the types of correlation are positive correlation, negative correlation, and no relation. This is calculated for the given condition using the below formula,
[tex]\text{correlation coefficient}=\frac{\text{covariance of security}}{\text{SD of security 1}\times\text{SD of security 2}}[/tex].
Here, the SD (standard deviation) is always positive, and the covariance value should be negative or less than zero so that the correlation coefficient of the two companies will be negative (as -0.95). From the given option, d is correct.

Which type of triangle can be constructed with a 50° angle between two 8-inch sides? A. Equilateral B. Isosceles C. Scalene D. Obtuse.
The correct option is (C) Isosceles. An Isosceles triangle can be constructed with a 50° angle between two 8-inch sides.
This is because isosceles triangle having two sides that are equal in length, and have 50° angle, which is acute angle, that is less than 90°. This state that the remaining angle in the triangle must also be acute triangle, as the sum of all angles in a triangle must equal 180°.
This means that the remaining angle must be 80° (i.e. 180 - 50 = 80). An isosceles triangle is triangle consisting of two sides of equal length and two angles of equal measure. The two equal sides that make up the isosceles triangle are referred to as the base and the remaining side is height or altitude.

Why is 587 divided by 187 0, but on the calculator it is 0. 357?
So the reason for the discrepancy between the calculated result and the result obtained by hand is due to how the remainder is being handled.
By hand, the remainder is kept as a separate value, whereas a calculator may display the result as a decimal instead of showing the remainder.
When dividing 587 by 187 by hand, the result would indeed be 0 with a remainder of 16:
3 | 5 8 7
- 5 6 1
-------
2 7 6
2 8 1
-----
9 6
Therefore, the quotient is 0 with a remainder of 16, which can also be written as 0.085 by dividing the remainder (16) by the divisor (187).
However, when using a calculator, it may display the result as a decimal instead of showing the remainder. In this case, the calculator would compute 587 divided by 187 as 3.136, which can be rounded to 0.357 if the result is being displayed to three decimal places.

The zeros at the end of a number can be significant if it contains decimal point only if the digit next to or at the end of the number (of decimal point) is a significant number.
Significant numbers of a given number are those digits that can convey the meaning of the number or what it stands for (measures as) according to its accuracy.
All non-zero numbers are significant numbers irrespective of the fact where they are positioned, that is they can be positioned before or after a decimal (also before or after a zero).
All zeros are not significant numbers and whetehr they are to be called significant numbers or depend on the fact where they are positioned and whether they convey any meaning (or value ) of the number.

What is the conversion of 70c to fahrenheit?
70 °C is equal to 158 °F.
A temperature unit developed from the SI (International System of Units) is the Celsius (symbol: °C).
Prior to the adoption of the metric system, the Fahrenheit (symbol: °F) was a commonly used measurement of temperature.
To convert a temperature from Celsius (°C) to Fahrenheit (°F),
We can use the following formula:
°F = (°C x 1.8) + 32
Where
°F is the temperature in Fahrenheit
°C is the temperature in Celsius.
Substituting 70 for °C,
We get:
°F = (70 x 1.8) + 32
Simplifying the expression:
°F = 126 + 32
°F = 158
Therefore, 70 degrees Celsius is equal to nearly 158 degrees Fahrenheit.

when we talk about measures of center, we look to the shape of the distribution to decide whether to use the mean or median. when do you think we should use the mean? (pick all that apply)
When the distribution is essentially symmetric or bell-shaped, with no extreme outliers, the mean is a useful measure of the center to employ. This is so because the mean can be impacted by extreme values, which can drive it away from the distribution's center, and is sensitive to the values of all the observations in the data set.
What is mean?In statistics, in addition to the mode and median, the mean is one of the measures of central tendency. Simply put, the mean is the average of the values in the given set. It indicates that values in a particular data set are distributed equally. The three most frequently used measures of central tendency are the mean, median, and mode. Assuming that the data is regularly distributed and that the mean is a suitable measure of center, the mean is often chosen when doing specific statistical procedures, such as linear regression and hypothesis testing.
The median, however, might be a better indicator of the center to utilize if the distribution is skewed or contains severe outliers. In these situations, the median better captures the distribution's midpoint and is less vulnerable to high extremes.
Which center measure to choose ultimately comes down to the specifics of the data collection and the objectives of the investigation.

what is 42 in base 5?
42 in base 5 is written as 132.
In mathematics, we often use different number systems, also known as bases, to represent numbers. The most commonly used number system is the decimal system, which is base 10. However, there are many other number systems, such as base 2, base 5, base 8, and so on. Each base system has its own set of digits that are used to represent numbers. In this explanation, we will focus on base 5 and how to convert the number 42 to base 5.
To convert a number to a different base system, we need to first understand the concept of place value. Place value is the value of a digit based on its position in a number. In the number 42, the digit 4 is in the tens place and has a value of 40 (4 x 10). The digit 2 is in the ones place and has a value of 2.
In base 5, we only have 5 digits to work with: 0, 1, 2, 3, and 4.
To convert the number 42 to base 5, we need to divide 42 by 5 and record the remainder.
We then divide the quotient by 5 again and record the remainder, and so on, until the quotient is 0.
42 ÷ 5 = 8 remainder 2
8 ÷ 5 = 1 remainder 3
1 ÷ 5 = 0 remainder 1
To convert these remainders into the corresponding digits in base 5, we simply read them from bottom to top. Therefore, 42 in base 5 is written as 132.

As per question,
We need to find the value of (6022*1023)
For finding the value of given expression, we will use the identity of multiplication.
So, applying the multiplication identity:
We can write the above as:
6022*1023 = (6000+22) * (1000+23)
As we know,
(a+b)*(c+d) = ac+ad+bc+bd
So, applying the identity in above expression,
We will get,
