Answer: 1.25

Step-by-step explanation:

Given: A college-entrance exam is designed so that scores are normally distributed with a mean[tex](\mu)[/tex] = 500 and a standard deviation[tex](\sigma)[/tex] =  100.

A z-score measures how many standard deviations a given measurement deviates from the mean.

Let Y be a random variable that denotes the scores in the exam.

Formula for z-score = [tex]\dfrac{Y-\mu}{\sigma}[/tex]

Z-score = [tex]\dfrac{625-500}{100}[/tex]

⇒ Z-score = [tex]\dfrac{125}{100}[/tex]

⇒Z-score =1.25

Therefore , the required z-score = 1.25

Answer:

6 yards is more, 6 yards converted into inches is 216

Step-by-step explanation:

Answer:

6 yards

Step-by-step explanation:

1 inch = 0.0277778 yard

=> 215 inches = 5.97222 yards

- But 5.97222 < 6

Therefore, 6 yards are longer than 215 inches

Answer:

x > 7

Step-by-step explanation:

-5x < -35

(Divide by 5)

-x < -7

(When dividing by a negative number, you flip the sign)

x > 7

The answer of given inequality is x > 7 .

Inequality is the defined as mathematical statements that have a minimum of two terms containing variables or numbers is not equal.

Given,

-5x < -35

Divide by 5 in inequality

-x < -7

Multiply by (-1) in inequality [flip the sign of inequality]

So, x > 7

9x² + 6x -19

Step-by-step explanation:

= 33x³ + 6x - 9 - 33x³ + 9x² -10

= 33x³ - 33x³ + 9x² + 6x -10 -9

= 9x² + 6x -19

Answer:

A sample of 139 should be taken.

Step-by-step explanation:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1 - 0.95}{2} = 0.025[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].

That is z with a pvalue of [tex]1 - 0.025 = 0.975[/tex], so Z = 1.96.

Now, find the margin of error M as such

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

Population standard deviation of $3,000.

This means that [tex]\sigma = 3000[/tex]

How large a sample should be taken if the desired margin of error is $500?

A sample of n is needed.

n is found when M = 500. So

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

[tex]500 = 1.96\frac{3000}{\sqrt{n}}[/tex]

[tex]500\sqrt{n} = 1.96*3000[/tex]

Dividing both sides by 500

[tex]\sqrt{n} = 1.96*6[/tex]

[tex](\sqrt{n})^2 = (1.96*6)^2[/tex]

[tex]n = 138.3[/tex]

Rounding up:

A sample of 139 should be taken.

Answer:

96 cm²

Step-by-step explanation:

From the question,

s = (2πr∅/360)+2r................. Equation 1

Where s = Perimeter of a sector, r = radius, ∅ = angle subtend by the sector at the center of the circle.

Given: s = 40 cm, r = 8 cm

Constant : π = 3.14.

Substitute into equation 1 and solve for ∅

40 = (2×8×3.14×∅/360)+(2×8)

40 = (50.24∅/360)+16

40-16 = 50.24∅/360

50.24∅/360 = 24

50.24∅ = 24×360

50.24∅ = 8640

∅ = 8640/50.24

∅ = 171.97°

Area of a sector (A') = ∅πr²/360

A' = 171.97×3.14×8²/360

A' = 95.997

A' ≈ 96 cm²

Answer:

x=5

∠ABD = 33

∠A = 115

Step-by-step explanation:

Once again here are the properties of a trapezoid:

Opposite angles are congruent

Opposite side lengths are congruent

And here is a property of a triangle:

the measure of the angles add up to equal 180

Given this information we need to find

x, ∠ABD and ∠A

First lets find x

Remember opposite side lengths are congruent

Segment AD and segment BC are opposite side lengths ( which are congruent)

That being said we create an equation to solve for x

2x = 10

step 1 divide each side by 2

2x/2=x

10/2=5

we're left with x = 5

Now lets find ∠A

∠C and ∠A are opposite angles

so ∠C≅∠A

Because ∠C = 115 ∠A also = 115

Finally lets find ∠ABD

because ∠BDC and ∠ABD are opposite angles we can find the measure of ∠BDC and get the value of ∠ABD

ΔBDC is a triangle formed within the parallelogram

That being said we can find the measure of ∠BDC using the triangle angle rule (stated previously)

That the measures of the angles in a triangle add up to equal 180

So we can find the missing angle (∠BDC) by subtracting the given angles ( which have a measure of 32 and 115) from 180

∠BDC = 180 - 32 - 115

180 - 32 - 115 = 33

so ∠BDC = 33

Meaning that ∠ABD also = 33

Answer:

5.66

Step-by-step explanation:

This is a 45 – 45 – 90 triangle. What this means is that the two legs are both congruent and the hypotenuse is the length of the legs times [tex]\sqrt{2}[/tex].

So in order to find this, we have to divide 8 by the square root of 2.

Putting this in to a calculator, we get 5.6568542. When rounded to the nearest hundredth, it is 5.66, which is the first answer.
