Answer 2

The required percentage that Cortney got correct on the test will be; 85.33%.

What is the percentage?

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

We have been given that Cortney got 64 out of 75 correct on a test.

We Need to determine the best estimate of the percentage Courtney got correct.

Here,

The Total question = 75

The correct question = 64

Then Percentage = 64 / 75 × 100

Percentage = 85.33%

Thus, the required percentage that Cortney got correct on the test will be; 85.33%.

Answers

Answer: 2 1/4

Step-by-step explanation:

From the question, we are informed that a baker made 9 cupcakes which are to be shared equally by four people.

To get the number of cupcakes that each person gets, we divide the total number of cupcakes by the total number of people. This would be:

M<2=x+88 can you please tell me the answer for this

Answers

Answer:

Answer: A) -8

Step-by-step explanation:

The image shows the triangle where it can be noted that two of its sides are congruent (according to the tick marks). This forms an isosceles triangle that also has two congruent angles as shown in the image below.

The other angle (2) has a measure of x+88.

The sum of the internal angles of the triangle must be 180°, thus:

x + 88 + 50 + 50 = 180

Simplifying:

x + 188 = 180

x = 180 - 188 = -8

x = -8

Answer: A) -8

The library has 65400 art books and 9600 science books. What part of all the books are science books

Answers

Answer:

9,600/75,000, 16/125

Step-by-step explanation:

art+science=75000

9600

75000    =16/125

The part of all the books that are science books is 0.128 or 16/125.

Using this formula

Science books=Science books(Art books+Science books)

Where:

Science books=9600

Art books=65400

Let plug in the formula

Science books=9600/(65400+9600)

Science books=9600/75000

Science books=0.128 or 16/125

Inconclusion the part of all the books that are science books is 0.128 or 16/125.

A number cube is rolled 360 times and the results are recorded as follows: 52 ones, 59 twos, 67 threes, 73 fours, 42 fives, and 67 sixes. What is the experimental probability of rolling a two or a three?

Answers

Answer:

0.35

Step-by-step explanation:

Total rolled = 360 times

Two rolled = 59

Three rolled = 67

Two rolled probability = 59/360 = 0.164

Three rolled probability = 67/360 = 0.186

The experimental probability of rolling a two or a three

==> Two rolled probability + Three rolled probability

==> 0.164 + 0.186

==> 0.35
