Answer: a = 1.25, b = 2.5, c = 1.25

Step-by-step explanation:

Use vertex form and substitute a point into it (1, 5)

5 = a(1 + 1)^2 + 0

5 = a(2)^2 + 0

5 = 4a

a = 5/4

y = 5/4 (x + 1)^2

y = 5/4 (x^2 + 2x + 1)

1.25 x^2 + 2.5x + 5/4

Is there a "c" value otherwise it's not possible

Answer:

15x + 7

Step-by-step explanation:

i set this up

8x + 16 + 7x -9

the next step is to combine like terms

8x + 7x = 15x

16 - 9 = 7

15x = 7

15x + 7

Complete question :

Wright et al. [A-2] used the 1999-2000 National Health and Nutrition Examination Survey NHANES) to estimate dietary intake of 10 key nutrients. One of those nutrients was calcium in all adults 60 years or older a mean daily calcium intake of 721 mg with a standard deviation of 454. Usin these values for the mean and standard deviation for the U.S. population, find the probability that a randonm sample of size 50 will have a mean: (mg). They found a) Greater than 800 mg b) Less than 700 mg. c) Between 700 and 850 mg.

Answer:

0.10935

0.3718

0.9778

0.606

Step-by-step explanation:

μ = 721 ; σ = 454 ; n = 50

P(x > 800)

Zscore = (x - μ) / σ/sqrt(n)

P(x > 800) = (800 - 721) ÷ 454/sqrt(50)

P(x > 800) = 79 / 64.205295

P(x > 800) = 1.23

P(Z > 1.23) = 0.10935

2.)

Less than 700

P(x < 700) = (700 - 721) ÷ 454/sqrt(50)

P(x < 700) = - 21/ 64.205295

P(x < 700) = - 0.327

P(Z < - 0.327) = 0.3718

Between 700 and 850

P(x < 850) = (850 - 721) ÷ 454/sqrt(50)

P(x < 850) = 129/ 64.205295

P(x < 700) = 2.01

P(Z < 2.01) = 0.9778

P(x < 850) - P(x < 700) =

P(Z < 2.01) - P(Z < - 0.327)

0.9778 - 0.3718

= 0.606

Answer: y-3x=12. y=3x+12. If the line is perpendicular it means its slope is the negative reciprocal of the given lines slope. m = 3 negative reciprocal = -1/3. So the slope of the equation of the line

Step-by-step explanation:

Answer:

-1/3

Step-by-step explanation:

(-1)(m)^(-1)

this is the way to make a slope perpendicular

y=mx+b

m=slope

b=y-intercept

so:

(-1)(3)^(-1)

-1/3 is the slope of the line that is perpendicular to y=3x-12

Answer:

The expected number of days per week the captain can leave port is 4.05.

Step-by-step explanation:

We are given the following distribution:

[tex]P(X = 0) = 0.2[/tex]

[tex]P(X = 1) = 0.05[/tex]

[tex]P(X = 2) = 0.05[/tex]

[tex]P(X = 3) = 0.05[/tex]

[tex]P(X = 4) = 0.15[/tex]

[tex]P(X = 5) = 0.1[/tex]

[tex]P(X = 6) = 0.15[/tex]

[tex]P(X = 7) = 0.25[/tex]

What is the expected number of days per week the captain can leave port.

We multiply each outcome by its probability. So

[tex]E = 0*0.2 + 1*0.05 + 2*0.05 + 3*0.05 + 4*0.15 + 5*0.1 + 6*0.15 + 7*0.25 = 4.05[/tex]

The expected number of days per week the captain can leave port is 4.05.

Answer:

29.25 / 29 1/4 MPH (Miles Per Hour)

Step-by-step explanation:

2/3 of an hour equals 40 minutes, so 19 1/2 miles is 40 minutes. 20 minutes is 1/3 of an hour, which is the missing amount of 2/3. Divide 19 1/2 miles by 2 to get 9 3/4 miles (which is how far Ms. Sanchez can go in 20 minutes). multiply by 3 to get 29 1/4 Miles Per Hour.

==========================================================

Explanation:

If you plug in x = -2, then,

y = 4x-2

y = 4(-2)-2

y = -8-2

y = -10

This shows that the answer must be choice D, as this is the only answer that has x = -2 lead to y = -10. Note the first column of table D.

We could stop here if you wanted.

----------------------

If we kept going and plugged in x = 0, then,

y = 4x-2

y = 4(0)-2

y = 0-2

y = -2

We have x = 0 lead to y = -2. This matches with the second column of table D.

-----------------------

Lastly, if we plugged in x = 2, then we get,

y = 4x-2

y = 4(2)-2

y = 8-2

y = 6

So the third column of table D is also confirmed.

Answer:

The mean average of all "six" students is 36.83.

Step-by-step explanation:

Mean:

The mean is the sum of all scores divided by the number of scores.

A group of five students have a mean test score of "34.2." Another student has a score of 50.

This means that the sum is given by:

[tex]S = 5*34.2 + 50 = 171 + 50 = 221[/tex]

What is the mean average of all "six" students?

Sum of 6 students is 221. So

[tex]M = \frac{221}{6} = 36.83[/tex]

The mean average of all "six" students is 36.83.

Answer:

48π

Step-by-step explanation:

Given that,

The radius of the sphere is increasing at a rate of 3cm/minute, [tex]\dfrac{dr}{dt}=3\ cm/minute[/tex]

The volume of a sphere is given by :

[tex]V=\dfrac{4}{3}\pi r^3[/tex]

Differentiating both sides wrt t.

[tex]\dfrac{dV}{dt}=\dfrac{4}{3}\pi \times 3r^2\times \dfrac{dr}{dt}\\\\=4\pi r^2\times \dfrac{dr}{dt}[/tex]

Put r = 2 cm and dr/dt = 3 cm/minute

So,

[tex]\dfrac{dV}{dt}=4\pi r^2\times \dfrac{dr}{dt}\\\\\dfrac{dV}{dt}=4\pi \times 2^2\times 3\\\\\dfrac{dV}{dt}=48\pi[/tex]

Hence, the correct option is (a) "48π".
