Answer:

55°

Step-by-step explanation:

180 - 35 - 90 = 55°

Answer:

55 degrees

Step-by-step explanation:

Hello There!

If you didn't know the measure of all of the angles in a triangle have a sum of 180

So to find a missing angle we subtract the two given angles from 180

We are given that one angle = 35 degrees

and another angle is a right angle

(a right angle measure 90 degrees)

Given this information we can find the missing angle of I

angle I = 180 - 90 - 35

180 - 90 - 35 = 55

so we can conclude that the measure of angle I is 55 degrees

Answer:

The average cost of a cat's annual visit is about $23.71 less at A New Leash on Life Animal Clinic than the average cost for a cat's annual visit at No Ruff Stuff Animal Hospital.

Explanation:

As you can see from the data and graph given, the Mean is essentially the average cost and $101.13 (New Leash on Life) is $23.71 less than $121.84 (No Ruff Stuff Animal Hospital).

I don't know the answer but someone who does will tell you.

Answer:

Approximately 256,140 recent college graduates have accumulated a student loan of more than $30,000.

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.

Average cumulative debt of recent college graduates is about $22,500, standard deviation of $7,000.

This means that [tex]\mu = 22500, \sigma = 7000[/tex]

Proportion more than 30000.

1 subtracted by the pvalue of Z when X = 30000. So

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

[tex]Z = \frac{30000 - 22500}{7000}[/tex]

[tex]Z = 1.07[/tex]

[tex]Z = 1.07[/tex] has a pvalue of 0.8577

1 - 0.8577 = 0.1423

Approximately how many recent college graduates have accumulated a student loan of more than $30,000?

0.1423 out of 1.8 million.

0.1423*1.8 = 0.25614 million = 256,140

Approximately 256,140 recent college graduates have accumulated a student loan of more than $30,000.

Most likely 2%.

Step-by-step explanation:

There’s a 20 sided dice and 100÷20=5

but you have to think of it as 26

2% x 26= 0.52 make 0.52 a 52 and take off the 2 from  52 and make it your answer, 2%

Answer:

34feet

Step-by-step explanation:

Using the pythagoras theorem

Hyp^2 = opp^2 + adj^2

Given

Hypotenuse = 40ft

Opp = 21ft

Required

Adjacent

Substitute

40^2 = 21*2 + adj^2

1600 = 441 + adj^2

adj^2 = 1600 - 441

adj^2 = 1159

adj = √1159

adj = 34.ft

Hence the missing length is 34feet

Answer:

x<1

Step-by-step explanation:

Treat it like a normal equation

Distribute: -3x-1>-7+3x

Isolate x: -6x>-7+1

Because we are dividing by a negative number, we need to flip the sign

x<1

Answer:

0, -1

Step-by-step explanation:

1. Plug in for 5:

-(15 + 1) > -7 + 15

-16 > 8 (FALSE)

2. Plug in for 1

-(3 + 1) > -7 + 3

-4 > -4 (FALSE, they are equal)

3. Plug in for 0

-(0 + 1) > -7 + 3(0)

-1 > -7 (TRUE)

4. Plug in for -1

-(-3 + 1) > -7 - 3

-(-2) > -10

2 > -10 (TRUE)

5. Plug in for 20

-(60 + 1) > -7 + 60

-66 > 53 (FALSE)

6. Plug in for -32

-(96 + 1) > -7 + 96

-97 > 89 (FALSE)

You can find the answer by just plugging in for x. It's very easy and the rest is just addition and multiplication, so please put some effort. Hope this helps! :)

Answer:

0.207 = 20.7% probability that exactly 10 of these are from the second section

Step-by-step explanation:

The students are chosen without replacement, which means that the hypergeometric distribution is used.

Hypergeometric distribution:

The probability of x sucesses is given by the following formula:

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]

In which:

x is the number of sucesses.

N is the size of the population.

n is the size of the sample.

k is the total number of desired outcomes.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

In this question:

20 + 30 = 50 total students, which means that [tex]N = 50[/tex]

30 students from the second section, which means that [tex]k = 30[/tex]

First 15 graded projects, so sample of 15, which means that [tex]n = 15[/tex]

a. What is the probability that exactly 10 of these are from the second section

This is P(X = 10).

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]

[tex]P(X = 10) = h(10,50,15,30) = \frac{C_{30,10}*C_{20,5}}{C_{50,15}} = 0.207[/tex]

0.207 = 20.7% probability that exactly 10 of these are from the second section

Reuben walks a total distance of 17500 meters in 7 days.

To find the total distance Reuben walks in 7 days, we can multiply his daily distance by the number of days.

Reuben walks 2.5 km every day, and we want to find the total distance in 7 days. To convert kilometers to meters, we know that 1 kilometer is equal to 1000 meters. Therefore, we can multiply the daily distance in kilometers by 1000 to get the daily distance in meters:

2.5 km/day * 1000 m/km = 2500 m/day

Now we can find the total distance walked in 7 days by multiplying the daily distance by the number of days:

2500 m/day * 7 days = 17500 meters

It's important to note that this calculation assumes Reuben walks the same distance every day without any variation. If his daily distance were to change, the total distance walked in 7 days would also change accordingly. Additionally, this calculation is based on the given information and assumes there are no rest days or breaks during the 7-day period.
