Answer:

The probability your mean age will be at least 28 is 83%

Step-by-step explanation:

Let X denote the ages of all new employees hired during the last 10 years , then X is normally distributed with;

a mean of 31

a standard deviation of 10.

The sample size obtained is 10 employees. This implies that the sampling distribution of the sample mean will be normal with;

a mean of 31

a standard deviation of [tex]\sqrt{10}[/tex]

The sample mean is a statistic and thus has its own distribution. Its mean is equal to the population mean, 31 and its standard deviation is equal to [tex]\frac{sigma}{\sqrt{n} }[/tex]

where sigma is the population standard deviation, 10 and n the sample size which in this case is 10. [tex]\frac{10}{\sqrt{10} }=\sqrt{10}[/tex]

We are required to find the probability that this sample mean age will be at least 28;

P(sample mean ≥ 28)

Since we know the distribution of the sample mean we simply standardize it to obtain the z-score associated with it;

P(sample mean ≥ 28)

= [tex]P(Z\geq \frac{28-31}{\sqrt{10} } )=P(Z\geq -0.9487)[/tex]

=0.8286

As a percentage this is equivalent to, 83%

Part 2) The system is solved using substitution

The cost  per can of grape juice is [tex]\$1.19[/tex] and the cost per can of apple juice is [tex]\$1.49[/tex]

Part 3) The system is solved by graphing

The graph in the attached figure

Step-by-step explanation:

Part 1) Solve the system by elimination

Let

x----> the cost per can of grape juice

y----> the cost per can of apple juice

we know that

[tex]6x+4y=13.10[/tex] -----> equation A

[tex]4x+6y=13.10+0.60[/tex]

[tex]4x+6y=13.70[/tex]  -----> equation B

Solve the system by elimination

Multiply the equation A by -6 both sides

[tex]-36x-24y=-78.6[/tex] -------> equation C

Multiply the equation B by 4 both sides

[tex]16x+24y=54.8[/tex] -------> equation D

Adds equation C and equation D

[tex]-36x-24y=-78.6\\16x+24y=54.8\\----------\\-36x+16x=-78.6+54.5\\-20x=-23.8\\x=1.19[/tex]

Substitute the value of x in the equation A

[tex]6(1.19)+4y=13.10[/tex]

[tex]4y=5.96[/tex]

[tex]y=1.49[/tex]

therefore

The cost  per can of grape juice is [tex]\$1.19[/tex]

The cost per can of apple juice is [tex]\$1.49[/tex]

Part 2) Solve the system by substitution

Let

x----> the cost per can of grape juice

y----> the cost per can of apple juice

we know that

[tex]6x+4y=13.10[/tex]    

[tex]4y=-6x+13.10[/tex]

[tex]y=-1.5x+3.275[/tex] -----> equation A

[tex]4x+6y=13.10+0.60[/tex]

[tex]4x+6y=13.70[/tex]  

[tex]6y=-4x+13.70[/tex]

[tex]y=-(4/6)x+13.70/6[/tex]

[tex]y=--0.67x+2.28[/tex] -----> equation B

Substitute equation B in equation A and solve for x

[tex]-0.67x+2.28=-1.5x+3.275[/tex]

[tex]1.5x-0.67x=3.275-2.28[/tex]

[tex]0.83x=0.995[/tex]

[tex]x=1.19[/tex]

Find the value of y

Substitute the value of x in the equation A

[tex]y=-1.5(1.19)+3.275=1.49[/tex]

therefore

The cost  per can of grape juice is [tex]\$1.19[/tex]

The cost per can of apple juice is [tex]\$1.49[/tex]

Part 3) Solve the system by graphing

we have

[tex]y=-1.5x+3.275[/tex] -----> equation A

[tex]y=-(4/6)x+13.70/6[/tex] -----> equation B

Remember that

The solution of the system of equations is equal to the intersection point both lines

The solution is the point [tex](1.19,1.49)[/tex]

see the attached figure

therefore

The cost  per can of grape juice is [tex]\$1.19[/tex]

The cost per can of apple juice is [tex]\$1.49[/tex]

1) What are the zeros of the function?

smaller r: -11, larger r: -14

2) What is the vertex of the parabola

Vertex: (-12.5, 3)

1. Zeros:

The zeros of the function occur when G(r) = 0. So we need to solve the equation:

-(r + 11)(r + 14) = 0

Since the product of two factors is zero when one or both factors are zero, we can set each factor equal to zero and solve for r:

r + 11 = 0 --> r = -11 (smaller r)

r + 14 = 0 --> r = -14 (larger r)

2. Vertex:

The function is given in factored form, which makes finding the vertex a bit easier. The vertex of a parabola in factored form is exactly between the two zeros.

Therefore, the x-coordinate of the vertex is:

(smaller r + larger r) / 2 = (-11 - 14) / 2 = -12.5

To find the y-coordinate (i.e., the function's value at the vertex), we can plug the x-coordinate of the vertex back into the function (G(r)). However, since the function is multiplied by -1, it might be easier to use one of the original zeros (say, r = -11).

G(-11) = -(-11 + 11)(-11 + 14) = 3 (notice how the negative sign cancels out)

Step-by-step explanation:

Download song .50

Download album = 4

Let s = number of songs

a = number of albums

She can spend 15 dollars

.5s +4a =15

If she downloads 6 songs, let s=6

.5(6) +4a = 15

3+4a = 15

Subtract 3 from each side

3-3+4a = 15-3

4a = 12

Divide by 4

4a/4 =12/4

a=3

She can buy 3 albums

If she downloads 1 album, let a=1

.5(s) +4(1) = 15

.5s +4=15

Subtract 4 from each side

.5s +4-4=15-4

.5s = 11

Divide by .5

.5s/.5 = 11/.5

s = 22

She can download 22 songs

If she downloads 30 songs, let s=30

.5(30) +4a = 15

15+4a= 15

Subtract 15 from each side

15-15 +4a = 15-15

4a=0

a=0

Answer:

After 7.5 seconds and a height of 0

Step-by-step explanation:

The time taken for the bolt to hit the elevator is 3 seconds, at a height of 60 feet.

Given that the elevator height is h(t)=20t while the bolt height is given by h(t)=-16t² + 200.

At the point when the bolt hit the elevator, they would be at the same height, hence:

-16t² + 200 = 20t

16t² + 20t - 200 = 0

t = -4.2 or t = 3

Therefore the time taken for the bolt to hit the elevator is 3 seconds, the height is:

h(3) = 20(3) = 60 feet

The time taken for the bolt to hit the elevator is 3 seconds, at a height of 60 feet.

Answer:

8 cups

Step-by-step explanation:

The number of cups of Gatorade served to the players during the last game was 8 cups.

To solve the problem, we need to determine how many cups are in half a gallon, given that 1 cup is equal to 1/16 of a gallon.

First, we establish the conversion factor between cups and gallons:

1 cup = 1/16 gallon

Now, we need to find out how many cups are in 1/2 gallon. To do this, we multiply the amount of Gatorade used in the last game by the conversion factor:

Cups served = (1/2 gallon) * (16 cups / 1 gallon)

Performing the multiplication:

Cups served = 1/2 * 16

Cups served = 8 cups

Therefore, 8 cups of Gatorade were served to the players during the last game.

Congruent is the same size and same shape. When a ray bisects an angle, the two newly created angles will be congruent, since the ray went right in the middle of the first angle (so in this case, ABC and DBC will be congruent)

Answer: C) ∠ABC & ∠DBC

Step-by-step explanation:

When a ray bisect an angle , then it divided the original angle into two congruent angles.

We are given that Ray BC bisects angle ABD.

Then, Ray BC divides ∠ABD into two congruent angles.

From the picture, The angle formed by it : ∠ABC & ∠DBC

So  ∠ABC & ∠DBC must be congruent.

Hence, the pair of angles must be congruent : ∠ABC & ∠DBC

Answer:

11,499 cm^3

Step-by-step explanation:

The volume of a sphere is given by the formula  [tex]V=\frac{4}{3}\pi r^3[/tex]

The radius is given as 14, we plug it into the formula and find the volume:

[tex]V=\frac{4}{3}\pi r^3\\V=\frac{4}{3}(\frac{22}{7}) (14)^3\\V=11498.66[/tex]

rounded to nearest integer, the volume is 11,499

Answer:

r=14 cm

V=11499 cubic cm

Step-by-step explanation:

If the radius of the sphere is r cm, then the perimeter of the largest cross section is the circumference of the circle qith radius r. Thus,

[tex]88=2\pi r,\\ \\r=\dfrac{88}{2\pi}=\dfrac{44}{\pi}=\dfrac{44}{\frac{22}{7}}=\dfrac{44}{1}\cdot \dfrac{7}{22}=14\ cm.[/tex]

Thvolume of the sphere can be calculated using formula

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

Since r=14 cm, we get

[tex]V=\dfrac{4}{3}\cdot \dfrac{22}{7}\cdot 14^3=\dfrac{4\cdot 22\cdot 2\cdot 14^2}{3}=\dfrac{34496}{3}\approx 11499\ cm^3.[/tex]

Answer:

(x- (-7))^2 + (y- (-3))^2 = 2^2

Simplify:

(x+7)^2 + (y+3)^2 = 4

there would be 12 combinations

Answer:

12

Step-by-step explanation:

We are given that tent hold 2,3,5,6 or 12 people.

We have to find the combinations of tents are possible to sleep 32 all tents are fully occupied and exactly one 12 person tent is used.

If one 12 person tents is used then remaining people=32-12=20

Therefore, 20 people that must be in other tents.

To place 20 persons in combination of 2,3,5 and 6.

20=5+5+5+5

20=5+5+5+2+3

20=6+6+6+2

20=2(10)=2+2+....+2(10 times)

20=5+5+2(5)(5 times add 2)

20=6+6+2(4) (4 times add 2)

20=3+3+3+3+3+3+2

20=3+3+3+3+3+5

20=3+2+6+5+2+2

20=3+3+3+3+6+2

20=3+3+5+5+2+2

20=6+6+3+5

Hence, there are 12 possible combination of tents  to sleep 32  all tents are fully occupied and exactly one 12 person tents is used.

Answer:

x² + 2x + [3\x - 1]

Step-by-step explanation:

Since the divisor is in the form of x - c, use what is called Synthetic Division. Remember, in this formula, -c gives you the OPPOSITE terms of what they really are, so do not forget it. Anyway, here is how it is done:

1| 1 1 -2 3

↓ 1 2 0

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

1 2 0 3 → x² + 2x + [3\x - 1]

You start by placing the c in the top left corner, then list all the coefficients of your dividend [x² + 5x - 36]. You bring down the original term closest to c then begin your multiplication. Now depending on what symbol your result is tells you whether the next step is to subtract or add, then you continue this process starting with multiplication all the way up until you reach the end. Now, when the last term is 0, that means you have no remainder, which in this case is a 3, so what you is set the divisor underneath the remainder of 3. Finally, your quotient is one degree less than your dividend, so that 1 in your quotient can be an x², 2 becomes 2x, and the remainder of 3 is set over the divisor, giving you the other factor of x² + 2x + [3\x - 1].
