Adrian's computer cost 20% less than Jocelyn's computer. Adrian's computer cost $640. Adrian's computer cost 15% more than Corbi

OLEGan [10]

Answer:

640 = .8j

640 = 1.15c

Step-by-step explanation:

Let j = cost of Jocelyn's computer

c = cost of Corbin's computer

We know that Adrian's computer costs $640.

Since Adrian's computer costs 20% less than Jocelyn's computer, the cost of Adrian's computer is 80% of (.8 times)the cost of Jocelyn's computer, so 640 = .8j

Since Adrian's computer costs 15% more than Corbin's computer, the cost of Adrian's computer is 115% of (1.15 times) the cost of Corbin's computer, so 640 = 1.15c

A sports statistician was interested in the relationship between game attendance (in thousands) and the number of

Luda [366]

Answer:

The predicted number of wins for a team that has an attendance of 2,100 is 25.49.

Step-by-step explanation:

The regression equation for the relationship between game attendance (in thousands) and the number of wins for baseball teams is as follows:

$\hat y = 4.9\cdot x + 15.2$

Here,

<em>y</em> = number of wins

<em>x</em> = attendance (in thousands)

Compute the number of wins for a team that has an attendance of 2,100 as follows:

$\hat y = 4.9\cdot x + 15.2$

$=(4.9\times 2.1)+15.2\\=10.29+15.2\\=25.49$

Thus, the predicted number of wins for a team that has an attendance of 2,100 is 25.49.

Answer:

a = 12 units

Step-by-step explanation:

Equation given is $a^2 + 16^2 = 20^2$

First we have to evaluate the powers.

$16^{2}$ = $16*16$ = $256$

$20^{2}$ = $20*20$ = $400$

So we can now write the equation again as:

$a^2 +256 =400$

Now we have to undo the addition,

$a^2=400-256$

$a^2=144$

Now we have to find the square root of $a^2$ to get the value of $a$

$\sqrt{a^{2}} = \sqrt{144}$

$a=12$ or $a=-12$

But the length of a leg cannot be a negative value, so we can take the +12.

a = 12 units
