The only true statement is A:

"The data show a negative linear relationship."

<h3></h3><h3>Which statement is true?</h3>

On the graph, we can see how the car's vale decreases almost linearly with the age of the car.

Where the response variable would be the one on the y-axis, which is the car's value.

For that linear behavior, we know that there is a correlation coefficient different than zero. So options B, C, and D are false.

Finally, we already saw the linear behavior (decreasing, so the slope is negative). Then we conclude that the only true statement is A.

70 POINTS!!!!!!!!!! Given: E, F, Q, D∈k(O),O ∈ ED, m∠DFQ = 10°, measure of arc EF = 28° Find: Angles of △EFQ

Likurg_2 [28]

Answer:

The measures of angles of triangle EFQ are

1) $m\angle EFQ=100\°$

2) $m\angle FEQ=66\°$

3) $m\angle EQF=14\°$

Step-by-step explanation:

step 1

Find the measure of arc QD

we know that

The inscribed angle is half that of the arc it comprises.

$m\angle DFQ=\frac{1}{2}(arc\ QD)$

substitute the given value

$10\°=\frac{1}{2}(arc\ QD)$

$20\°=(arc\ QD)$

$arc\ QD=20\°$

step 2

Find the measure of arc FQ

we know that

$arc\ QD+arc\ FQ+arc\ EF=180\°$ ---> because ED is a diameter (the diameter divide the circle into two equal parts)

substitute the given values

$20\°+arc\ FQ+28\°=180\°$

$arc\ FQ=180\°-48\°=132\°$

step 3

Find the measure of angle EFQ

we know that

The inscribed angle is half that of the arc it comprises.

$m\angle EFQ=\frac{1}{2}(arc\ QD+arc\ ED)$

substitute the given value

$m\angle EFQ=\frac{1}{2}(20\°+180\°)=100\°$

step 4

Find the measure of angle FEQ

we know that

The inscribed angle is half that of the arc it comprises.

$m\angle FEQ=\frac{1}{2}(arc\ FQ)$

substitute the given value

$m\angle FEQ=\frac{1}{2}(132\°)=66\°$

step 5

Find the measure of angle EQF

we know that

The inscribed angle is half that of the arc it comprises.

$m\angle EQF=\frac{1}{2}(arc\ EF)$

substitute the given value

$m\angle EQF=\frac{1}{2}(28\°)=14\°$

What is 14 divided by 6

Licemer1 [7]

$14:6=\frac{14}{6}=\frac{14:2}{6:2}=\frac{7}{3}=\frac{6+1}{3}=\frac{6}{3}+\frac{1}{3}=2\frac{1}{3}\\\\\frac{1}{3}=0.\overline3\ therefore\ 14:6=2.\overline3$

For the sentence y=5x-2, what are the missing y values in this table

ANTONII [103]

Y=5x-2 so you have to solve for x
Make y = 0
Then
Y=5x-2
+2. +2
2=5x
Divide by five
X= 2/5
Then
Y=5x-2
Put x into the equation
Y=5(2/5)-2
Y=2-2
Y=0
Done I hope that help (＾∇＾)

Harry ate 3/8 of a large pizza. Aidan ate 1/2 of a small pizz. Harry said that since 4/8 is equivalent to 1/2,he and Aidan ate t

-BARSIC- [3]

Harry is incorrect. If Harry only ate 3/8 of the pizza and Aidan ate 1/2 of the pizza, Harry ate less pizza. Because 1/2 equals 4/8 and 4/8 is greater than 3/8, Aidan ate more pizza than Harry.

Hope this helps!!

What is the explicit rule for the arithmetic sequence shown in the graph?

Harman [31]

Answer:

a(n) = 9.5 + 2(n - 1)

Step-by-step explanation:

Observe that each new term is obtained by adding 2 to the previous term. Thus, the common difference is 2 and the first term is 9.5.

Then a(n) = 9.5 + 2(n - 1)
