For the function below, find ordered pairs for: x = -2 and x = 5 y = 9 - 4x

Answers

Answer:

(- 2, 17 ) and (5, - 11 )

Step-by-step explanation:

Given

y = 9 - 4x

Substitute the given values of x into the equation and evaluate for y

x = - 2, then

y = 9 - 4(- 2) = 9 + 8 = 17 ⇒ (- 2, 17 ) ← ordered pair

x = 5, then

y = 9 - 4(5) = 9 - 20 = - 11 ⇒ (5, - 11 ) ← ordered pair

The tensile strength of paper is modeled by a normal distribution with a mean of 35 pounds per square inch and a standard deviation of 2 pounds per square inch.

Required:
a. What is the probability that the strength of a sample is less than 38 lb/in²?
b. If the specifications require the tensile strength to exceed 30 lb/in², what proportion of the samples is scrapped?

Answers

Answer:

a) the probability that the strength of a sample is less than 38 lb/in² is approximately 0.9332

b) approximately 0.62% of the sample are scrapped

Step-by-step explanation:

a)

What is the probability that the strength of a sample is less than 38 lb/in²?

lets X rep the paper tensile strength in pounds per square inch.

the probability that the strength of the sample is less than 38 lb/in²

i.e P( X < 38 )

so assuming that X is normally distributed with u = 35 lb/in² and α = 2 lb/in²,

so the probability expression P( X < 38 ) can be standardized as

P( X < 38 ) = P( (X-35)/2  < (38-35)/2)  

= P( X < 1.5 )  

from the cumulative standard normal distribution table,

we find P( X < 1.5 )  =  0.9332

so

P( X < 38 ) = P( X < 1.5 )  

= 0.9332

therefore the probability that the strength of a sample is less than 38 lb/in² is approximately 0.9332

b)

If the specifications require the tensile strength to exceed 30 lb/in², what proportion of the samples is scrapped?

this can be represented as P( X < 30 )

By standardization the probability expression  P( X < 30 ) can be transformed as;

P( X < 30 ) = P( (X-35)/2 < (30-35)/2)  

=  P( z < -2.5 )

from the cumulative standard normal distribution table,

we find P( X < -2.5 )  =  0.0062

so

P( X < 30 ) = P( X < -2.5 )  

= 0.0062

therefore, approximately 0.62% of the sample are scrapped

Answers

Question:

The most common type of harmony in the Baroque Period was

answer: Harmony came to be thought of as chords that laid the foundation for the melody. Major and minor as we know them today became established as keys instead of modes, and the harmonic patterns of tonality began to evolve. hmm

Polyphony is having multiple voices, harmony is how those multiple voices interact and relate to each other. Polyphony doesn't necessarily mean playing at the same time either, just the act of having multiple voices in a piece. Melodic independence and consonant treatment. so i think it is                                                       A.Polyphony

Shen’s mother gave him $10 to go buy groceries. He picked up a gallon of milk for $3.49, three pounds of oranges that cost $1.14 per pound, and a box of cereal for $3.46. Shen used front-end estimation to determine whether he had enough money for the groceries. How much did he estimate the total cost would be?

He estimated that he had about $7 worth of groceries.
He estimated that he had about $9 worth of groceries.
He estimated that he had about $10.30 worth of groceries.
He estimated that he had about $10.40 worth of groceries.

So 10.45 is closest to 10.40 and you have to remeber that this is just an estimate so it will be less because we rounded the answer up.

Hope this helps

Answer:

$9 its be heres my work

Step-by-step explanation:

Gallon of milk: $3.49

3lbs oranges: $1.14(3) = $3.42

Box of cereal: $3.46

Front end estimation is taking the number in front and the rest of the numbers coming after it will be zeroes.

Using front end estimation:

$3.49 => $3.00

$3.42 => $3.00

$3.46 => $3.00

Add all these up; Shen estimated the total cost of the groceries would be $9.00.

As x subject, the linear equation is x = 1/4(w -c).

What is linear equation?

Equations whose variables have a power of one are called linear equations. One example with one variable is where ax+b = 0, where a and b are real values and x is the variable.

We have a linear equation,

4x+c=w.

To make x a subject:

4x = w - c

x = 1/4(w -c)

Find the measures of Angles A,B, and C

Answers

Answer:

A = 102   B = 78   C = 56

Step-by-step explanation:

All three sides of a triangle added up equals 180.

So 41 + 37 + A = 180

A = 102

A straight line = 180 degrees.

One measurement is 102, so the other is 78.

You now know B is 78, and that 3 angles equal 180.

46 + 78 + c = 180

c= 56

In the game of roulette, there is a wheel with spaces marked 0 through 36 and a space marked 00. Find the probability of winning if you pick the number 30 and it comes up on the wheel. Round your answer to 3 decimal places. Answer:

Answers

Answer:

Step-by-step explanation:

Total out come is 38

Favorable outcome is 1

Probability is 1/38 ≈ 0.026

The probability of winning if you pick the number 30, and it comes up on the wheel, will be 0.026.

What is probability?

Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.

In the game of roulette, there is a wheel with spaces marked 0 through 36 and a space marked 00.

Then the total number of the event will be

Total event = 38 {0, 00, 1, 2, …, 36}

Then the probability of winning if you pick the number 30, and it comes up on the wheel will be

Favorable event = 1 {30}

Then the probability will be

P = 1 / 38

P = 0.026

Round intermediate calculations to at least 4 decimal places. Round your final answers to 2 decimal places.) x −41 −27 −8 −3 P(X = x) 0.29 0.35 0.21 0.15

Answers

Answer:

a) Mean is -23.47

b) Variance is 206.59

c) standard deviation is 14.37

Step-by-step explanation:

Given that;

 x              −41        −27        −8         −3

P(X = x)      0.29      0.35      0.21      0.15

X.P            -11.89     -9.45    -1.68     -0.45

a) mean

Mean = ∑X.P = -11.89 +  -9.45 + -1.68 + -0.45

Mean = -23.47

b)  the variance

E(x²) = ∑x²P(X=x)

= (−41²×0.29) + (−27²×0.35) + (−8²×0.21) + (−3²×0.15)

= 487.49 + 255.15 + 13.44 + 1.35

= 757.43

So

Var(X) = E(x²) - [∑X.P]²

Var(X) = 757.43 - [-23.47]²

= 757.43 - 550.8409

= 206.5891 ≈ 206.59

Therefore Variance is 206.59

c) standard deviation

standard deviation SD(X) = √Var(X)

SD(X) = √206.5891

= 14.3732 ≈ 14.37

Therefore standard deviation is 14.37

Use a number line to show the difference between the amounts of pizza eaten by the two competitors in one minute.



pls help i really need this answer

Answers

Using number line, the difference in the amount of Pizza they ate is 0.75

What is the difference between the amounts of pizza eaten by the two competitors in a minute?

To compare the amounts of pizza eaten by Sandy and James in 1 minute, we need to first calculate how many slices they eat in 1 minute.

Sandy can eat 6.5 slices in 2 minutes, which means she can eat 6.5/2 = 3.25 slices in 1 minute.

James can eat 3 slices in 1.5 minutes, which means he can eat 3/(1.5/2) = 4 slices in 1 minute.

Therefore, James can eat more pizza in 1 minute than Sandy.

To show the difference on a number line, we can mark 3.25 and 4 on the line, and subtract 3.25 from 4 to get the difference:

         0         1         2         3         4

         |---------|---------|---------|---------|

Sandy:                   3.25

James:                   4

Difference:             0.75

So the difference between the amounts of pizza eaten by James and Sandy in 1 minute is 0.75 slices.
