-1/32ac2

You want to cancel out the -32 on the top with the 64 on the bottom leaving -1. Then do the same with the variables.

The language arts function has the greater slope. Then the correct option is C.

<h3>What is the linear system?</h3>

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

The tables show linear functions representing the estimated time it takes for the math and language arts portions of standardized tests with different numbers of questions.

The table is shown below.

The slope of math will be

Slope of math = (207 - 87)/ (65 - 25)

Slope of math = 120/40

Slope of math = 3

The slope of language arts will be

Slope of language arts = (248 - 88)/(60 - 20)

Slope of language arts = 160/40

Slope of language arts = 4

The language arts function has the greater slope, which shows that the estimated time per question for language arts is less than the estimated time per question for math.

More about the linear system link is given below.

What is the area of this parallelogram?

Lorico [155]

Step-by-step explanation:

Parallelogram formula: $A=b(base)h(height)$

The value 6 is meant to trick you.

The height is 7, and the base is 10 1/4.

Multiply the base and height:

$7 \times 10\frac{1}{4} = 71\frac{3}{4}$

The area equals: $71\frac{3}{4}$ $ft^{2}$

Choose an SRS of 1000 men from this population. Now what is the probability that x falls within ±2 mg/dL of μ? The larger sample

anyanavicka [17]

Answer:

(a) 0.5398

(b) 0.06376

Step-by-step explanation:

Given u=118, SD = 25, n = 10

Since we are dealing with a stratified random sampling (SRS)

We use,

Z = X - U/(Sd/√n).

The required probability =

Pr(112 < Z < 114)

Pr(112< Z< 114)=Pr( Z<114) - Pr(Z<112)

=Pr [Z<(114-118)/(25/√100)] - Pr[Z<(112-118)/(25/√100)]

= Pr(Z<-1.6) - PR(Z<-2.4)

= 0.5498 - 0.00820

= 0.5398

(b) Now since we are considering the whole population of 1000 men we use

Z = (X - U)/Sd

Now we the Probability of Pr(118±2)= Pr(120, 116)

= Pr(116 < X <120)

Pr(118±2) = Pr(Z<120-118/25) - Pr(Z<116-118/25)

Pr(118±2) = Pr(Z<0.08) - Pr(Z< -0.08)

= 0.53188 - 0.46812

Pr(118±2)= 0.06376

Please note the complete form of this question was gotten through Google.

A government sample survey plans to measure the LDL (bad) cholesterol level of an SRS of 100 men aged 20 to 34. Suppose that in fact the LDL cholesterol level of all men aged 20 to 34 follows the Normal distribution with mean μ = 118 milligrams per deciliter (mg/dL) and standard deviation σ = 25 mg/dL.

(a) What is the probability that

¯¯¯

x takes a value between 114 and 122 mg/dL? This is the probability that

¯¯¯

x estimates μ within ±4 mg/dL.

(b) Choose an SRS of 1000 men from this population. Now what is the probability that

¯¯¯

x falls within ±4 mg/dL of μ? The larger sample is much more likely to give an accurate estimate of μ.
