Tenaya earned 82 points on one math test and 94 points on the next test. Elena earned 94 points on the first test and then 82 po

jek_recluse [69]

Answer:

Total test score of Tenaya and Elena are same.

Step-by-step explanation:

Given:

Points earned by Tenaya on one math test = 82

Points earned by Tenaya on next math test = 94

Points earned by Elena on first math test = 94

Points earned by Elena on next math test = 82

We need to Compare the total test scores for Tenaya to the total scores for Elena.

Solution:

First we will find the Total test score of Tenaya and Elena.

Now we can say that;

Total test score of Tenaya is equal to sum Points earned by Tenaya on one math test and Points earned by Tenaya on next math test.

framing in equation form we get;

Total test score of Tenaya = $94+82 = 176\ points$

Total test score of Elena is equal to sum Points earned by Elena on one math test and Points earned by Elena on next math test.

framing in equation form we get;

Total test score of Elena = $94+82 = 176\ points$

Hence from we can say that Total test score of Tenaya and Elena are same.

On his first day of school, Kareem found the high temperature in degrees Fahrenheit to be 76.1°. He plans to use the function C

BARSIC [14]

Answer:

(A)the temperature of 76.1 degrees Fahrenheit converted to degrees Celsius

Step-by-step explanation:

Kareem plans to use the function $C(F) = \dfrac59(F-32)$ to convert temperature from degrees Fahrenheit to degrees Celsius.

The function gives a result in degrees Celsius. Therefore, 76.1 is in degree Fahrenheit and the result C(76.1) will be in degree Celsius.

Therefore, C(76.1) represents the temperature of 76.1 degrees Fahrenheit converted to degrees Celsius.

The correct option is A.

Elan Coil [88]

Answer:

0.92 and 1.25 respectively

Step-by-step explanation:

0.92 and 1.25 respectively

first the mean of each value which is 9.7 and 9.8 respectively

standard deviation = square root of the mean deviation of each value

then deduct the mean from each element

and square each value and add them together. not you should square each deviation value before you add them

at last divide the result by the number of frequency and find it's square root

In a bag of candy, Marsha found that there were 7 red, 8 blue, 5 yellow, and 9 greens pieces of candy. Marsha put all of the pie

son4ous [18]

Answer:

Step-by-step explanation:

1) find the total candies

7 + 8 + 5 + 9 = 29

2) a probability can be expressed with a fraction whose denominator is the total candies, while the numerator represents the candies that we want to find

- red = 7/29

- blue = 8/29

- yellow = 5/29

- green = 9/29

3) compound probability

(red + blue)/29 = 15/29

(yellow + green)/29 = 14/29

(blue + yellow + green)/29 = 22/29
