A cafeteria manager can choose from among six side dishes for the lunch menu: applesauce, broccoli, corn, dumplings, egg rolls, or French fries. He uses a computer program to randomly select three dishes for Monday’s lunch.

Answers

Answer:

0.20

Step-by-step explanation:

Given : The number of side dishes for the lunch menu =6

The number of ways to select 3 dishes from 6 :

Total outcomes :                    

If applesauce and broccoli is already selected , then we need to select only one dish out of remaining 4 dishes.

Number of ways to select 1 dish from 4 :

Favorable outcomes:  

Now, the theoretical probability that applesauce and broccoli will both be offered on Monday :-

Hence, the theoretical probability that applesauce and broccoli will both be offered on Monday = 0.20

Now, suppose assuming the true fraction of voters is .65, the estimated standard deviation of X is given as 6.65. Suppose you find that 115 people actually voted yes in the random sample of 200. Conduct hypothesis testing using p value approach at 5% significance level to determine the validity of Candidate A’s claim that he was at least supported by 65% of the voters. (Make sure you show the steps of hypothesis testing)

Answers

Answer:

reject H0 ; conclude that there is significant evidence to conclude that candidate A is supported by less than 65% voters

Step-by-step explanation:

x = 115

n = 200

Phat = x / n = 115 / 200 = 0.575

H0 : P0 ≥ 0.65

H1 : P0 < 0.65

TEST STATISTIC :

Phat - P0 ÷ sqrt[(P0(1-P0))/n]

0.575 - 0.65 ÷ sqrt[(0.65(0.35))/200]

-0.075 ÷ 0.0337268

Test statistic -2.237

Pvalue :

P(Z < - 2.237) = 0.012643

α = 0.05

Pvalue < α

0.012643 < 0.05 ; We reject H0

We can conclude that there is significant evidence to conclude that candidate A is supported by less than 65% voters

Find the distance between the points (1,–5) and (9,9).

Answers

Answer:

[tex]\sqrt{260\\[/tex] or 16.12

Step-by-step explanation:

distance formula is [tex]} d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}[/tex]

Distance (d) = √(9 - 1)2 + (9 - -5)2

= √(8)2 + (14)2

= √260

= 2√65

= 16.124515496597

Triangle ABC is similar to DEF. Which proportion can be used to find the length of DE in centimeters?

Answers

Answer:

[tex]\frac{DE}{4} = \frac{9}{3}[/tex]

[tex]DE = 12[/tex]

Step-by-step explanation:

Given

See attachment for triangles ABC and DEF

Required

The proportion to find DE

To solve for DE, we can make use of the following equivalent ratios;

[tex]AB:DE = BC:EF[/tex]

Substitute values for AB, BC and EF

[tex]4:DE = 3:9[/tex]

Express as fractions

[tex]\frac{DE}{4} = \frac{9}{3}[/tex]

The above is the proportion to solve for DE

Solving further:

[tex]\frac{DE}{4} = 3[/tex]

[tex]DE = 4 * 3[/tex]

[tex]DE = 12[/tex]

Answers

Answer:

D

Step-by-step explanation:

Básicamente  sumas esos 2 y se lo restas a 180.

Answer:

D. 86

Step-by-step explanation:

since the angles of a triangle add up to equal 180, all you have to do is add the angles you know and then find the one you don't by subtracting it from 180.

this is how it looks mathematically:

180=26+68+x

180=94+x

180-94=x

x=86

Zoey takes out a loan of $25,000 to pay for a car. Her interest rate is 3% for 60 months. How much will Zoey pay in total for the car?

Answers

Answer: $28750

Step-by-step explanation:

Since 12 months = 1 year, it should be noted that 60 months = 60/12 = 5 years.

Simple interest = Principal × Rate × Time

= $25000 × 3% × 5

= $25000 × 0.03 × 5

= $3750

The total amount that Joey will pay for the car will be the value of the principal plus the interest which will be:

= $25000 + $3750

= $28750

Answer:

LA = 120 sq cm

SA = 132 sq. cm.

Step-by-step explanation:

LA = ph    where p = perimeter of the base and h = the height of prism.

Your base is a triangle.  The third side = [tex]\sqrt{5^{2} - 3^{2} }[/tex] = [tex]\sqrt{25 - 9} = \sqrt{16} = 4[/tex]

Now, the perimeter of the triangle is 3 + 4 + 5 = 12

So, LA = 12(10) = 120 sq cm

The area of the base is the area of a triangle.  A = bh/2 = 4(3)/2 = 6

SA = 2B + LA      where B is the area of the base

SA = 2(6) + 120 = 12 + 120 = 132 sq. cm.
