Can someone help me pls

Answer/Step-by-step explanation:

The triangle given is a right triangle

Reference angle = angle E

Thus:

The side that is opposite to angle E is side DF = e

The side that is adjacent to angle E is side EF = d

The hypotenuse side is the longest side that is opposite go the right angle of the triangle = DE = f

Answer:

The point is [tex]\mu - 98[/tex], in which [tex]\mu[/tex] is the average per month.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Normal distribution with an average of per month and a standard deviation of​ $50 per month.

Average of [tex]\mu[/tex], standard deviation [tex]\sigma = 50[/tex]

Find the point in the distribution below which​ 2.5% of the​ PCE's fell.

This is below the 2.5th percentile, which is the X when Z has a pvalue of 0.025, so X when Z = -1.96.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]-1.96 = \frac{X - \mu}{50}[/tex]

[tex]X - \mu = -1.96*50[/tex]

[tex]X = \mu - 98[/tex]

The point is [tex]\mu - 98[/tex], in which [tex]\mu[/tex] is the average per month.

Answer:

r = 100 km/hr is the average speed of the car.

Step-by-step explanation:

The formula which relates distance d, time t, and speed or rate of travel r is:

d = rt.

We're given that the distance traveled d = 50 km and the time t traveled = 30 minutes = 1/2 hr. Substituting this given information into the distance-rate-time formula for d and t to find r, we get:

50 km = r(1/2 hr)

Now, dividing both sides by 1/2 hr, we have:

50 km/(1/2 hr) = [r(1/2 hr)]/(1/2 hr)

50 km/(1/2 hr) = r[(1/2 hr)/(1/2 hr)]

[50 km/(1/2)] km/hr = r[(1/2 hr)/(1/2 hr)]

50(2/1) km/hr = r[1]

100 km/hr = r[1]

r = 100 km/hr is the average speed of the car.

Answer:

choice 1: m = 6 1/2

Step-by-step explanation:

m - 2 1/2 = 4

add 2 1/2 to each side of the equation:

m - 2 1/2 + 2 1/2 = 4 + 2 1/2

m = 6 1/2

Answer:

a= $54764.26

Step-by-step explanation:

r=R/100

r=4.5/100

r=0.045 rate per year

A = P(1 + r/n)nt

A = 10,000.00(1 + 0.045/4)(4)(38)

A = 10,000.00(1 + 0.01125)(152)

A = $54,764.26

Answer:

$2,800

Step-by-step explanation:

The formula for simple interest is I = PRT, where I is the interest (earned or paid), P is the principal amount invested/borrowed, R is the rate in decimal form, and T is the time in years.

I = (2000)(0.05)(8)

I = $800

Then we add that to the principal to get $2,800

---------------------------------

Joey made a deposit into an account that earns 6% simple interest. After 3 years, Joey earned $400. How much was Joey's initial deposit?

I = PRT

400 = P(0.06)(3)

400 = 0.18P

P = $2,222. 22

Peter is calculating the interest earned on a deposit of $275 in an account that earns 8% simple interest after 12 years. What is the ??? guessing interest earned?

I = PRT

I = (275)(0.08)(12)

I = $264

Given:

Mike gets an 8% commission on the sporting goods that he sells.

One day he sold sporting goods worth 1,384.

To find:

The commission for that day.

Solution:

According to the given information,

Commission = 8% of total sales of sporting goods

One day he sold sporting goods worth 1,384. Then, the commission for that day is

[tex]\text{Commission}=\dfrac{8}{100}\times 1384[/tex]

[tex]\text{Commission}=\dfrac{11072}{100}[/tex]

[tex]\text{Commission}=110.72[/tex]

Therefore, the commission for that day is 110.72.

Answer:

m(arc FE) = 166°

Step-by-step explanation:

By theorem of intersecting chords and tangent of a circle,

Measure of the angle formed by a chord and tangent intersecting on the circle measure the half of the intercepted arc.

m(∠GFE) = [tex]\frac{1}{2}\text{m (arc} FE)[/tex]

83° = [tex]\frac{1}{2}\text{m (arc} FE)[/tex]

m(arc FE) = 166°

Answer:

See attachment for image

Step-by-step explanation:

Given

[tex]Width = 9[/tex]

[tex]Perimeter = 40[/tex]

Required

The image that illustrates the patio

The question is incomplete as the possible images are not given. So, I will attach an image that illustrates the scenario.

But first, the length of the patio must be calculated using perimeter formula

[tex]Perimeter = 2 *(Length + Width)[/tex]

[tex]40 = 2 *(Length + 9)[/tex]

Divide both sides by 2

[tex]20 = Length + 9[/tex]

Solve for Length

[tex]Length = 20 - 9[/tex]

[tex]Length = 11[/tex]

This implies that the dimension of the patio is 11 units by 9 units (See attachment)
