Answer:

Step-by-step explanation:

The only two numbers that would make the whole expression divisible by 8 are 0 and 8. Since the number also has to be divisible by 5, though, the last digit must be a 0 or a 5. Therefore, A=0. Hope this helps!

I believe the answer is B.

Explanation: In the problem, it states that “Karen says MOST middle school students’ favorite band is Rhonda and the Gees.” Pay attention to the keyword, most. Only 65 students like Rhonda and the Gees, so it is too small to represent a middle school of 1,156. So, therefore, the answer should be B.

Answer:

Kindly check explanation

Step-by-step explanation:

Given the data:

Temperature (degrees Celsius) : 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30

Percent heat loss from beak : 35 36 38 28 41 43 55 46 39 54 45 58 60 56 62 67

Using an online regression calculator ; the regression equation obtained is :

ŷ = 2.0927X + 0.6029

X = independent variable

Y = predicted variable

2.0927 = slope

0.6029 = intercept

B.) temperature = 25

ŷ = 2.0927(25) + 0.6029

= 52.9204

C.) the explained variance is the value of the coefficient of determination (R²) which is the square of the correlation Coefficient

0.8785² = 0.7718

D.) the correlation Coefficient r is 0.8785 using the Coefficient of regression calculator

Which rule gives the same relationship between x and y as x + y = 6?

igor_vitrenko [27]

x + y = 6

relationship: x = 6 -y or y = 6-x

so answer: c. y = 6 - x

show work:

x + y = 6

subtract x to both sides

x + y -x = 6 -x

simplify

y = 6-x
