Answer: 16

Step-by-step explanation:

Guests = x

5x/8 = 10

x = 16

16 guests can be served with 10 pounds of chocolate when estimated each guest at the party eat 5/8 pounds of chocolate.

it's is estimated that each guest at the party will eat 5/8 pounds of chocolate. We need to find number of guests can be served with 10 pounds of chocolate

Two expressions with an equal sign is called as equation.

When it's is estimated that each guest at the party will eat 5/8 pounds of chocolate. We need to find number of guests can be served with 10 pounds of chocolate.

we need to divide 10 by 5/8 to find the answer

10/(5/8)=10*8/5=80/5=16

Therefore 16 Guests can be served with 10 pounds of chocolate.

Answer:

d. lower bound: 528-2-10, upper bound: 528+2*10; (508, 548)

Step-by-step explanation:

The computation of the approximate 95% confidence interval is shown below:

Given that

mean = 528,

standard deviation = 10

[tex]Mean \mp z_{\frac{0.05}{2}}\times standard\ deviation \\\\=528 \mp 2 \times 10\\\\=(508,548)[/tex]

hence, the correct option is d.

The confidence interval gives a range of estimate for the true population mean at a given confidence level. The confidence interval for the mean is lower bound: 528-2-10, upper bound: 528+2*10; (508, 548)

The confidence interval for the mean is obtained using the relation :

Plugging in the values :

528 ± (1.96 × (10))

Approximating Z* (1.96) = 2.00

Lower boundary = 528 - (2 × 10) = 528 - 20 = 508

Upper boundary = 528 + (2 × 10) = 528 + 20 = 548

Therefore, the confidence interval is lower bound: 528-2-10, upper bound: 528+2*10; (508, 548)

Answer:

1. 75 feet

2. 27 seconds

Step-by-step explanation:

1. If six seconds is equal  to 10 feet that means that 42 seconds is equal to 70 feet (6 X 7 = 42) It also means that 3 seconds is equal to 5 feet. (42 + 3 = 45)

2. If 6 seconds is 10 feet, then 6 X 4 is 40 feet (24) And since 5 feet is equal to   3 seconds then we get 24 + 3 = 27

Answer:

[tex]r=\frac{L}{2pi R}[/tex]

Diameter=2r

inches=12*ft

Step-by-step explanation:

You forgot to say how far the bike travels.

Given R rotations, L feet, and a wheel radius of r, then the relationship is

[tex]L=2\pi rR[/tex]

Solving this for r gives

[tex]r=\frac{L}{2pi R}[/tex]

Diameter=2r

Answer:

45% and 55%

Step-by-step explanation:

Total student = 20

No of Girls = 9

No of boys = Total student - No of Girls

                  =20-9

                  =11

Percentage of Girls = (No of Girls / Total student) * 100

                           = (9/20)*100

                           = 45 %

Percentage of Boys = (No of Boys/ Total student) * 100

                           = (11/20)*100

                           = 55 %

Step-by-step explanation:

AOD - since it forms a triangle and the sides of the triangle are radius of circle they are equal so ADO = DAO. to find AOD: 180⁰-36⁰-36⁰=108⁰.

ODC - first we find DOC :180⁰-108⁰=72⁰.since the other 2 sides of the triangle are equal we can find ODC by : 180⁰=72⁰+2x

2x=180⁰-72⁰

2x=108⁰

x=108⁰/2

x=54⁰

the other 3 right now i dont have an idea but if i think of it later i will comment it here.

ABC -its 120⁰ because it forms Z angles with CEF

CFD -first we find ODE which we do by : 90⁰-54⁰=36⁰. Then we find CED by : 180⁰-120⁰=60⁰.Then we find DCE by: 180⁰-36⁰-60⁰=84⁰.Then we find ECF by :180⁰-54⁰-84⁰=42⁰.And now we find CFD by : 180⁰-120⁰-42⁰=18⁰.

CAB -first we find BCA by : 180⁰-54⁰-84⁰=42⁰ or you can say it is equal with ECF because they are opposites of the same point.Then to find CAB we : 180⁰-120⁰-42⁰=18⁰ or you can say it is equal to CFD because they form Z angle.

The correct equation which reveals the maximum height reached by the model rocket is,

h = - 16 (t + 4)² - 304

What is Quadratic equation?

An equation of order 2 in highest variable is called a Quadratic equation.

Given that;

The equation is,

H = -16t² + 128t + 48

Now, The equation which reveals the maximum height reached by the model rocket is find as;

H = -16t² + 128t + 48

h = -16(t² + 8t) + 48

h = -16 (t² + 8t) + 256 - 256 + 48

h = -16 (t² + 8t + 16) + 256 + 48

h = -16 (t + 4)² + 304

Thus, The correct equation which reveals the maximum height reached by the model rocket is,

h = - 16 (t + 4)² - 304

Answer: 15

Step-by-step explanation:

The 11th term of arithmetic progression is 43. We can use this to get the common difference which will be:

a + (n - 1)d = 43

where,

a = first term = 3

n = nth term = 11

d = common difference = unknown

Therefore, a + (n - 1)d = 43

3 + (11 - 1)d = 43

3 + 10d = 43

10d = 43 - 3

10d = 40

d = 40/10

d = 4

Common difference = 4

Therefore, 4th term will be:

= a + (n - 1)d

= a + (4-1)d

= a + 3d

= 3 + 3(4)

= 3 + 12

= 15

The 4th term is 15

Answer:

f(2) = 0 and f(6) = -4

Step-by-step explanation:

First, find f(x) when x = 2

Plug in 2 as x in the function:

f(x) = -(x - 2)​

f(2) = -(2 - 2)

f(2) = -(0)

f(2) = 0

Next, find f(x) when x = 6. Plug in 6 as x in the function:

f(x) = -(x - 2)​

f(6) = -(6 - 2)

f(6) = -(4)

f(6) = -4

So, f(2) = 0 and f(6) = -4

Answer:

x = 4

y = 4

Step-by-step explanation:

the front triangle has two 40° angles (sum of all ∡'s must be 180°)

the unlabeled lower-left angle then is 40°; this angle corresponds to the angle in the other triangle labeled as 10y°

therefore, 10y = 40 so y = 4

Since opposite angles in a parallelogram are congruent then we can write:

40° + 25x° = 100° + 10(4)°

25x° = 140 - 40°

25x = 100°

x = 4

Answer:

I suppose that the inequality is:

(1/11)*c > 9.

To solve this we need to isolate c in one side of the inequality.

To isolate it, we need to multiply both sides by 11, then we get:

11*(1/11)*c > 9*11

c > 9*11 = 99

c > 99.

To graph this, we will have an open dot at c = 99, and an arrow that points to the right direction.
