Suppose that the probability that it rains on Friday is 80% and the probability that it rains on Saturday is 70%, and the event that it rains on Friday is independent of the event that it rains on Saturday. Find the probability that it DOES NOT RAIN on Friday and it DOES NOT RAIN on Saturday.
A sample of five scores was taken. They were 82, 73, 61, 97, and 83. Find the SAMPLE standard deviation of the scores. (Round to 2 decimal places).
The scores on a nationwide are normally distributed with a mean of 120 and a standard deviation of 20. Find the probability that a randomly selected test-taker scored less than 105. (Round to 4 decimal places)

Answers

Answer:

0.06 (6%)

13.31

0.2266

Step-by-step explanation:

1)

Given that :

Probability that it rains on Friday ; P(FR) = 0.8

Probability that it rains on Saturday ; P(SR) = 0.7

P(FR) and P(SR) are independent events

Probability that it does not rain on Friday ; P(FR)' = 1 - P(FR) = 1 - 0.8 = 0.2

Probability that it does not rain on Saturday ; P(SR)' = 1 - P(SR) = 1 - 0.7 = 0.3

Hence, probability that it does not rain on Friday and on Saturday ;

P(FR)' * P(SR)' = 0.2 * 0.3 = 0.06 = 0.06 * 100% = 6%

2)

Given the scores :

82, 73, 61, 97, 83 ;

The sample standard deviation :

Sqrt(Σ(X - m)^2 ÷ n - 1)

n = sample size = 5

m = mean = ΣX / n

m = (82 + 73 + 61 + 97 + 83) / 5 = 79.2

Sqrt((82 - 79.2)^2 + (73 - 79.2)^2 + (61 - 79.2)^2 + (97 - 79.2)^2 + (83 - 79.2)^2) / (5 - 1)

Sqrt(177.2) = 13.311649

Hence, standard deviation = 13.31

3.)

Given that :

Mean(m) = 120

Standard deviation (s) = 20

Probability that randomly taken test taker scores less than 105

P(x < 105)

Obtain the standardized score :

Z = (x - m) / s

Z = (105 - 120) / 20

Z = - 15 / 20

Z = - 0.75

P(Z < - 0.75) = 0.22663 (Z probability calculator)

= 0.2266

Question
Simplify: (-12az2-22³)+(-2a³ +7a²z)-(-4a²z+8az²).

Answers

Step-by-step explanation:

if I take the expression as you wrote it literally, we have

(-12az2 - 22³) + (-2a³ + 7a²z) - (-4a²z + 8az²) =

= -24az - 10,648 - 2a³ + 7a²z + 4a²z - 8az² =

= -24az - 10,648 - 2a³ + 11a²z - 8az²

yet when I assume that there were several typos particularly in the first bracket, my guess about the real original expression is

(-12az² - 2a³) + (-2a³ + 7a²z) - (-4a²z + 8az²) =

= -12az² - 2a³ - 2a³ + 7a²z + 4a²z - 8az² =

= -20az² - 4a³ + 11a²z

Luca hired a plumber to fix his sink. She charged $95.50 per hour. If the job took 1.5 hours, how much did Luca owe the plumber?

Answers

Answer:

143.25

Step-by-step explanation:

First, you know that 95.50 is an hour well it's 1 hour and 30 minutes( because 1 is the hour and the 5 is half of ten so the 5 would equal 30) so 95.50 divided into 2 is 47.75 so 95.50+47.75=143.25

Step-by-step explanation:

An investment has probabilities 0.15, 0.34, 0.44, 0.67, 0.2 and 0.15 of giving returns equal to 50%,
39%, -4%, 20%, -25%, and 42%. What are the expected returns and the standard deviations of
returns?

Answers

The expected returns is 33.7% and the standard deviations of returns is 38.73%.

What is standard deviation?

In statistics, the standard deviation is a measure of the amount of variation or dispersion of a set of values.

Now given probabilities are,

probabilities P = 0.15, 0.34, 0.44, 0.67, 0.2 and 0.15

Given returns on the probabilities,

returns r = 50%, 39%, -4%, 20%, -25%, and 42%

So, Expected rate of returns = ∑Pr

Expected rate of returns = 0.15(50) + 0.34(39) + 0.44(-4) + 0.67(20) + 0.2(-25) + 0.15(42)

Expected rate of returns = 7.5 + 13.26 - 1.76 + 13.4 - 5 + 6.3

Expected rate of returns = 33.7%

Now standard deviation S is,

Square root of the difference squared between each value and the mean, multiplied by the probability.

S = √{0.15(50 - 33.7)² + 0.34(39 - 33.7)² + 0.44(-4 - 33.7)² + 0.67(20 - 33.7)² + 0.2(-25 - 33.7)² + 0.15(42 - 33.7)²}

⇒ S  = √{0.15(16.3)² + 0.34(5.3)² + 0.44(-37.7)² + 0.67( - 13.7)² + 0.2(-58.7)² + 0.15(8.3)²}

⇒ S  = √{0.15(265.69)+ 0.34(28.09) + 0.44(1421.29) + 0.67( - 187.69) + 0.2(3445.69)²\ + 0.15(68.89)}

⇒ S  = √{39.85 + 9.55 + 625.36 + 125.75 + 689.13 + 10.33}

⇒ S  = √{1499.97}

⇒ S  = 38.73%

Thus, the expected returns is 33.7% and the standard deviations of returns is 38.73%.

The store is selling lemons at $0.66 each. Each lemon yields about 2 tablespoons of juice. How much will it cost to buy enough lemons to make three 9-inch lemon pies,each requiring half a cup of lemon juice?​

Answers

Answer:

$7.92

Step-by-step explanation:

1 lemon = 2 tbsp = $0.66

1 pie = 1/2 cup

So take 3 x 1/2 = 1 1/2 cups. Now we know that we need 1 1/2 cups of lemon juice. So convert 1 1/2 cups into tbsp and you get 24 tbsp. Now since 1 lemon is equal to 2 tbsp divide the 24 tbsp by 2 and you get 12. This 12 represents the amount of lemons you need to buy. Since 1 lemon is $0.66 take that and multiply it by the amount of lemons you need (12x0.66) now you get $7.92.

You need $7.92 to but 12 lemons to make three 9 inch lemon pies.

What is the unitary method?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

1 cup of lemon juice requires around 16 tablespoons of of juice.

1 lemon = 2 tbsp = $0.66

1 pie = 1/2 cup

number of cups = 3 x 1/2 = 1 1/2 cups.

Now we know that we need 1 1/2 cups of lemon juice.  convert 1 1/2 cups into tablespoons and you get 24 tablespoons .

Now since 1 lemon is equal to 2 tbsp divide the 24 tbsp by 2

number of tablespoons = 24/2 = 12.

This represents the amount of lemons you need to buy.

Since 1 lemon is $0.66 take that and multiply it by the amount of lemons number of lemons = (12x0.66) =  $7.92.

WE need $7.92 to but 12 lemons to make three 9 inch lemon pies.

The total cost of your purchase.

Answers

The total purchase is  $18.90.

What is the total purchase?

A discount would reduce the cost of the purchase. A tax increases the cost of the purchase.

The first step is to determine the total cost of the items purchased.

Total cost = (cost of lb of cheese x lb bought) + (cost of sliced ham x lbs bought) + (cost of bread x loaves bought) + (cost of a bag of potato chips x number of bags bought) + (cost of one salsa container x number of containers bought)

(1.99 x 1/2) + (3 x 3.29) + (1.59 x 2) + (2 x $3) + (1.39 x 1) = $20.39

Since, the total cost is greater than $20 she qualifies for the 10% discount

Total cost after the discount = (1 - 0.1) x $20.39

0.9 x $20.39= $18.35

Cost after the tax = (1 + 0.03) x $18.35

1.03 x $18.35 = $18.90
