Answer:

Step-by-step explanation:

To find the coordinates, count the number of lines from the last marked line. The x coordinate will be found by counting the numbers side to side. In this case, the x is -8. The y coordinate is found by counting the numbers up and down. In this case, the y is 7.

the length of a rectangle is 6in.more than than its width .Its area is 50 sq.in Find the width of the rectangle....

yulyashka [42]

L=6+W
A=LW
sub 6+W for L
A=(6+W)(W)
expand
oh, A=50
50=W²+6W
minus 50 both sides
0=W²+6W-50
we gots to use quadratic formula
for
aW²+bW+c=0
W= $\frac{-b+/- \sqrt{b^2-4ac} }{2a}$
we got
a=1
b=6
c=-50

W= $\frac{-(6)+/- \sqrt{(6)^2-4(1)(-50)} }{2(1)}$
W= $\frac{-6+/- \sqrt{36+200} }{2}$
W= $\frac{-6+/- \sqrt{236} }{2}$
W= $\frac{-6+/- 2\sqrt{59} }{2}$
W= $-3+/- \sqrt{59}$

W= $-3+ \sqrt{59}$ or W= $-3- \sqrt{59}$
aprox
W=-10.6811 or W=4.68115
can't be negative width

width=4.68115 or -3√59

Which is the best estimate of the correlation coefficient for the scatter plot?

olga55 [171]

Answer:

The best estimate of the correlation coefficient is 0.9 from the given data.

Step-by-step explanation:

From the scatter plot, the line of best fit will have a positive slope.

So, the correlation coefficient , $\rho$ is greater than 0.

so, $\rho$ ≠ - 0.9

Also, there is a deviation from absolute linearity.

So, $\rho$ ≠ 1

Again from the scatter plot it is closer to linearity than further.

Hence, $\rho$ ≠ 0.3 .

So $\rho$ = 0.9

What is the fully factored form of 32a^3 + 12a^2?

Klio2033 [76]

<u>Answer:</u>

$4a^{2} (8a + 3)$

<u>Step-by-step explanation:</u>

32a^3 + 12a^2

To factorize this, start by taking the common variable out. As we have two powers for the same variable a, we can take the smaller power of a as a common to get like shown below:

32a^3 + 12a^2

a^2 (32a + 12)

Now when you have taken the variable as a common, try and take out a common number from the coefficient of a as well:

a^2 (32a + 12)

4a^2 (8a + 3)

So, the fully factored form of 32a^3 + 12a^2 is 4a^2 (8a + 3).

The city zoo has different admission prices for adults and children. When three adults and two children went to the zoo, the bil

charle [14.2K]

Answer:

The price of adult's ticket is $ 17.73 And

The price of children's ticket is $ 13.85

Step-by-step explanation:

Given as :

The Prices for adult ticket and child ticket in the city zoo is different

Let the price for adult's ticket = $ A

And The price for child's ticket = $ C

Now, according to question :

3 A + 2 C = $ 80.89 And

2 A + 3 C = $ 77.01

Now solve the both equation

So, 2 × (3 A + 2 C) = 2 × $ 80.89 And

3 × (2 A + 3 C) = 3 × $ 77.01

I.e

6 A + 4 C = $ 161.78 And

6 A + 9 C = $ 231.03

Now, ( 6 A + 9 C ) - ( 6 A + 4 C ) = $ 231.03 - $ 161.78

Or, 5 C = $ 69.25

Or, C = $ 13.85

And Put the value of C in above any eq

6 A + 4 × ($ 13.85) = $ 161.78

Or, 6 A = $ 161.78 - $ 55.4

Or, 6 A = $ 106.38

∴ A = $\frac{106.38}{6}$

Or, A = $ 17.73

Hence The price of adult's ticket is $ 17.73 And

The price of children's ticket is $ 13.85 Answer
