Answers

Answer: the percentage you would get the number two would be 10% out of 100 I believe. Hope it helped!

I think the probability of selecting a multiple of 2 is 50%.

Explanation: The multiples of 2 from 1-10 are 2,4,6,8, and 10. That’s 5 numbers out of 10. That means the chances of selecting a multiple of 2 is half, 50%.

(in order) 196, 198, 248, 276, 289, 319, 349, 379  there are eight numbers.

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

196, 198, 248, 276

since the median is between 198 and 248, we must add both numbers together and divide them by two:

(198 + 248) ÷ 2

= 446/2

= 223 (first quartile)

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

289, 319, 349, 379

since the median is between 319 and 349, we must add both numbers together and divide them by two:

school every day at a rate of 6 miles per hour. How

to reach home from school each day? Be sure to
SHOW your WORK!

Answers

Answer:

Noah takes 20 minutes to get to his house, that is, 10 minutes less than Charlotte.

Step-by-step explanation:

Since Charlotte walks home from school every day at a rate of 4 miles per hour and it takes her 30-minutes to reach home, while her brother, Noah, runs home from the same school every day at a rate of 6 miles per hour, to determine how many fewer minutes does it take Noah than Charlotte to reach home from school each day the following calculation must be performed:

Charlotte:

4 mph = 4/60 = 0.0666 miles per minute

0.0666 x 30 = 2 miles

So the distance from the school to her house is 2 miles

Noah:

6/60 = 0.1 mile per minute

2 / 0.1 = 20

Thus, Noah takes 20 minutes to get to his house, that is, 10 minutes less than Charlotte.

Given tan0 = 7/24 use the Pythagorean theorem to find the value of sin 0

Answers

Answer:

Step-by-step explanation:

Don't use 0 (or any other number) to replace θ. Use a letter variable such as x.

tan(x) = 7/24

sin(x)/cos(x) = 7/24

sin(x) = 7/√(7²+24²) = 7/√625 = 7/25

Which function represents the graph?
O y=-3cos(x)
O y=-3sin(x)
O y = 3cos(x)
O y = 3sin(x)

Answers

The function which represents the graph is : D. y = 3sin(x)

What is function?

"A function is an expression which assigns each element of X to exactly one element of Y from a set X to a set Y."

What is the graph of function?

"The graph of a function f is the set of all points in the plane of the form (x, f(x))."

What is the graph of sine function?

"The graph of y=sin(x) is like a wave that oscillates between -1 and 1, in a shape that repeats itself every units.

Also, the graph of sine function passes though origin, as sin(0) = 0 ."

What is the graph of cosine function?

"The graph of y=cos(x) is like the graph of y=sin(x) but shifted horizontally by π units"

From given graph, we can observe that the graph must be of sine function.

Also, given graph represents the graph of y = sin(x) expanded 3 times.

So, the function which represents the graph is, y = 3sin(x).

Hence, the correct answer is option D. y = 3sin(x)

Answer:

the future value is $5,750.01

Step-by-step explanation:

The computation of the future value is shown below;

As we know that

Future value = Present value × (1 + rate of interest)^number of years

= $5,000 × (1 + 0.035 ÷ 12)^4 × 12

= $5,000 × (1 + 0.2916%)^48

= $5,750.01

Hence, the future value is $5,750.01

25% of Mr. Foster's class chose an amber background for their school picture. If 6 students chose an amber background, how many students are in Mr. Foster's class?

Answers

Answer:

24 students

Step-by-step explanation:

25% of a hundred is one-fourth and because there are six students in a fourth of the whole we are multiplying four and six. 6x 4 is 24.

The percentage is calculated by dividing the required value by the total

value and multiplying by 100.

Required percentage value = a

total value = b

Percentage = a/b x 100

25% = 6 students

100% = 24 students

The total number of students in Mr. Foster's class is 24.

What is a percentage?

The percentage is calculated by dividing the required value by the total

value and multiplying by 100.

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Number of students who chose an amber background = 6

25% of Mr. Foster's class chose an amber background for their school picture.

This means,

25% = 6

The total number of students = 100%

Now,

25% = 6 students

Multiply 4 on both sides.

4 x 25% = 4 x 6 students

100% = 24 students

Thus,

The total number of students in Mr. Foster's class is 24.
