Answer:

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 3 , thus

y = - 3x + c ← is the partial equation

To find c substitute (7, 8) into the partial equation

8 = - 21 + c ⇒ c = 8 + 21 = 29

y = - 3x + 29 → A

Jorge (J), Marcus (M) and Ren (R) want to pool their Pokemon cards together. Jorge has two times the amount of cards that Marcus

Oxana [17]

Answer:

Marcus has 494 cards.

Jorge has 988 cards.

Ren has 518 cards.

Step-by-step explanation:

Let x represent Marcus's cards.

M + J + R

(x) + (2x) + (x+24) = 2000

x + 2x + x + 24 = 2000

4x +24 =2000

4x = 1976

x = 494

Human body temperatures have a mean of 98.20° F and a standard deviation of 0.62°. Sally's temperature can be described by z = -

STALIN [3.7K]

Answer:

$97.27^{o}F$

Step-by-step explanation:

We have been given that human body temperatures have a mean of 98.20° F and a standard deviation of 0.62°. Sally's temperature can be described by z = -1.5.

To find Sally's temperature we will use z-score formula.

$z=\frac{x-\mu}{\sigma}$ , where $\mu$ = Mean, $\sigma$ = Standard deviation.

Let us substitute our given values in z-score formula.

$-1.5=\frac{x-98.20}{0.62}$

Multiply 0.62 to both sides of equation.

$0.62\times-1.5=0.62\times \frac{x-98.20}{0.62}$

$-0.93=x-98.20$

Add 98.20 to both sides of equation.

$-0.93+98.20=x-98.20+98.20$

$97.27=x$

Therefore, Sally's temperature will be 97.27 degrees Fahrenheit.
