A sports medicine major wanted to conduct an experiment to determine if there is a correlation between the members of the soccer team's leg strength and the time it takes for them to sprint 40 yards. He sets up the following test and records the data:

Answers

Answer 1

Answer:

The time for 22 leg-press reps is 11.9 seconds.

Step-by-step explanation:

The lines of best fit is the trend line of the dataset.

The equation of line of best fit is y = 0.120x + 9.274The time for 22 leg-press reps is 11.9 seconds(A) The equation of the line of best fit

The table is given as —

(x) : 12 32 7 26 28 15 1

(y) : 8.6 14.6 7.1 8.3 11.9 19.4 9.5

To determine the equation of line of best fit, we make use of a regression calculator.

Enter the above dataset in a regression calculator, the equation is: y = 0.120x + 9.274 (Approximated to Three Decimal Places / Rounded of to the Thousandths Place)

(B) The number of seconds for 22 leg-press reps

This means that x = 22.

So, we have:

y = 0.120 * 22 + 9.274

= 2.640 + 9.274

= 11.914

(Approximate to the nearest hundredths)

= 11.9

Hence, the time for 22 leg-press reps is 11.9 seconds.

Hope my answer helps you.

Answers

Answer:

Y=74, x=106.

Step-by-step explanation:

First, if you will notice, that 16+Y=90. Why? Because there is a square instead of a semicircle at the angle, which means that 16+Y=90. 90-16=74, so Y is 74. Then, we see that 90 plus an unknown angle equals x. But, using a rule of geometry, we know that the unknown angle is 16. So, x=90+16, and since 90+16 is 106, we get Y=74, X=106.

On monday, your bank account balance was -$12.58. Because you didn't realize this, you wrote a check for $30.72 for groceries. a) What is the new balance in your checking account? b) The bank charges a $25 fee for playing a check on a negative balance. What is the balance in your checking account after this fee? c) How much money do you need to deposit to bring your account balance back up to $0 after the fee?

Answers

Answer:

a) The new balance in your checking account is -$12.58 - $30.72 = -$43.30.

b) After the bank charges a $25 fee for overdrafting, the balance in your checking account will be -$43.30 - $25 = -$68.30.

c) To bring your account balance back up to $0 after the fee, you will need to deposit $68.30.

Step-by-step explanation:

Answer:

First, you subtract the 30.72 from the -12.58 which is -43.03 which is therefore how much you have in your account. Then we subtract another 25 for the fee. -68.03 Is how much you have after paying the fee.

Therefore, to get to 0, you need to pay 68 dollars and 3 cents.

The expressions are only equivalent when evaluated with even values. The expressions have equivalent values for any value of x. The expressions should have been evaluated with one odd value and one even value. When x = 0, the first expression has a value of 4 and the second expression has a value of 5.
