I F 49x ²b = (7x +1/2)(7x-1/2)<br>then Find the value b.

Marina86 [1]

Answer:

Step-by-step explanation:

Apply Only the Outside and Inside Method of the Foil Method.

$7 \times - \frac{1}{2} = - 3.5x$

$\frac{1}{2} \times 7x = 3.5x$

Add them together

$- 3.5x + 3.5x = 0$

So our b value is 0.

Seventy-six percent of sunflower seeds will germinate into a flower, and a sample of 800 such sunflower seeds is randomly select

ollegr [7]

Answer:

12.08

Step-by-step explanation:

For each sunflower, there are only two possible outcomes. Either it germinates, or it does not. The probability of a sunflower germinating is independent of other sunflowers. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

The standard deviation of the binomial distribution is:

$\sqrt{V(X)} = \sqrt{np(1-p)}$

Seventy-six percent of sunflower seeds will germinate into a flower

This means that $p = 0.76$

Samples of 800:

This means that $n = 800$

The standard deviation for the number of sunflower seeds that will germinate in such samples of size 800 is:

$\sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{800*0.76*0.24} = 12.08$

Points (-21, 5) and (-7,y) have a slope of 5. Find the y coordinate of the point.

hjlf

Answer:

Step-by-step explanation:

The equation of finding a slope is y2-y1/x2-x1.

y-5/-7-(-21)=5

y-5/-7+21=5

y-5/15=5

y-5=75

y=80
