Step-by-step explanation:

we don't see the parallelogram nor any description of it.

so, it is impossible to tell you the right answer.

as I only answer questions by don't ask any, I don't know how you can add a picture.

Only about 75% of all donated human blood can be used in hospitals. The remaining 25% cannot be used because of various infectio

Tresset [83]

Answer:

a) 0.02739

b) 0.00034

Step-by-step explanation:

If it is believed that at least 6 of the 10 pints are usable, then the 75% of “good” pints that can be used from this sample reduces to 60% of 75% = 0.6*0.75 = 0.45

Now for this sample we use a binomial distribution with probability of “success” (finding a “good” pint) of 0.45% and

the probability of getting exactly r good pints out of 10 is

$\bf \binom{10}{r}0.45^r(1-0.45)^{10-r}=\binom{10}{r}0.45^r0.55^{10-r}$

where

$\bf \binom{10}{r}$ are combinations of 10 taken r at a time.

a)

The probability that at least 8 of the pints are usable is P(r>7)

$\bf \binom{10}{8}0.45^80.55^2+\binom{10}{9}0.45^90.55^1+\binom{10}{10}0.45^{10}0.55^0=\\0.02289+0.00416+0.00034=0.02739$

b)

Here we want P(r=10)

$\bf \binom{10}{10}0.45^{10}0.55^0=0.00034$

You sell eggs from the farm at a price of 3 for $2.00, 6 for $3.50, 12 for $6.00, and 24 for $13.00. What is the approximate per

KonstantinChe [14]

Answer:

Best deal: 12 for $6

Worst deal: 3 for $2

29.06% difference

Step-by-step explanation:

2.00/3= 0.67

3.50/6= 0.58

6.00/12= 0.50

13.00/24= 0.54

Best deal: 12 for $6

Worst deal: 3 for $2

% difference: (0.67-0.50)/((0.67-0.50)/2) x 100= 29.06% difference

Answer:

An equation in the slope-intercept form will be:

y = 15x+210

Step-by-step explanation:

We know The slope-intercept form of the line equation

$y = mx+b$

where

m is the rate of change or slope

b is the y-intercept

Let x represent the time in months

Let y represent the amount of money remaining in the account.

Given that every month Monica withdraws $15 from this account for her contact lenses

Thus, the rate of change or slope = m = 15

Given that after 3 months she has $255 left in her account.

So, we take the point (3, 255)

substituting m = 15, x = 3 and y = 255 in the slope-intercept form to determine the y-intercept

y = mx+b

255 = 15(3) + b

switch sides

15(3) + b = 255

45 + b = 255

b = 255 - 45

b = 210

Now, substituting m = 15 and b = 210 in the slope-intercept form of the line equation

y = mx+b

y = 15x+210

Therefore, an equation in the slope-intercept form will be:

y = 15x+210
