Answer:

-2x+8

Step-by-step explanation:

so lets start

you want to distribute the -2 to the parenthesis

so -2(x) = -2x and -2(-4) = 8 because of 2 negatives make a positive

so then you just add them

-2x+8

Answer: $-2x + 8$

Step-by-step explanation:

In order to simplify this we must distribute the -2 to the values inside of the parentheses.

$-2*x = -2x\\\-2 * -4 = 8$

Since two negatives are being multiplied, the product is a positive number.

The final simplified answer is $-2x + 8$ .

In a genetics experiment on peas, one sample of offspring contained green peas and yellow peas. Based on those results, estimate

pashok25 [27]

Answer:

The probability of getting an offspring pea that is green is is 0.733

YES, the probability is reasonably close to the expected value of 3/4 (0.750)

Step-by-step explanation:

The formula for calculating the probability of an event is;

P = Favorable Outcome / Sample space

Let A be an event of getting an offspring green peas, B be an event of getting an offspring yellow peas and N be the total number of peas.

number of green peas in an offspring are 350

number of yellow peas in an offspring are 127

total number of peas are 477

So in the genetic experiment, the number of times event A occurs is 350 and the number times event B occurs is 127

Now the probability of getting an offspring pea that is green is

P = number of green peas / total number of peas

p = n(A)/N

p = 350/477

p = 0.733

So YES, the probability is reasonably close to 3/4 ( 0.750 )

The probability of getting an offspring pea that is green is is 0.733.

YES, the probability is reasonably close to the expected value of 3/4 (0.750)

The black graph is the graph of y=f(x). Choose the equation for the red graph.<br> Please help!!

yan [13]

Answer:

Step-by-step explanation:

The black graph is the graph of y=f(x).

The red graph is the reflection of the black graph across the y-axis.

A. $y=f(x-1)$ determines the translation of the graph $y=f(x)$ one unit to the right.

B. $y=f\left(\dfrac{x}{-1}\right)$ determines the reflection of the graph $y=f(x)$ across the y-axis.

C. $y-1=f(x),\ y=f(x)+1$ determines the translation of the graph $y=f(x)$ one unit up.

D. $\dfrac{y}{-1}=f(x),\ y=-f(x)$ determines the reflection of the graph $y=f(x)$ across the y-axis.
