Answer:

a) 10 inches

b) 48 feet

Step-by-step explanation:

10 inches, 60/6 = 10

48 feet, 8*6 = 48

Answer:

x = 12

Step-by-step explanation:

We will label the unknown interior angle of the triangle d.

14x - 19 + d = 180

14x + d = 199

d = 199 - 14x

199 - 14x + 3x + 9x + 7 - 2 = 180

199 - 2x +5 = 180

204 - 2x = 180

204 = 180 + 2x

2x = 24

x = 12

Answer:

5.04*10³

Step-by-step explanation:

5.04*10³

Answer:

a. Semester 1: 86.8, Semester 2: 87

b. Semester 1: 5.7, Semester 2: 6.3

c. Semester 1 because the standard deviation of the first semester was lower than of the second. This shows that his scores were closer to the mean and therefore he was more consistent.

Step-by-step explanation: Find the mean by taking the sum of the values for each semester and divide that sum by the number of values to find the average. Do this for both semesters. Now, find the absolute value of the difference between the mean and each value of the corresponding data set. Square each if those differences and sum them up. Now divide that sum by the number of data values and take the square root. This number is your standard deviation. You will use the standard deviations to make the comparison for part c. I hope this makes sense and helps!!!!

Answer:

Step-by-step explanation:

Chords having equal measures are equidistant from the center of the circle.

Since, VW = XY

Therefore, ZP = ZR = 15 units

A perpendicular line drawn from the center of a circle to the chord is the bisector of the chord.

VR = WR = 20 units

By applying Pythagoras theorem in ΔZRV,

ZV² = ZR² + VR²

ZV² = (15)² + (20)²

ZV = √(225 + 400)

ZV = √625

ZV = 25 units

Therefore, measure of radius ZV = 25 units.

VW = XY [Given]

Therefore, XY = 2(20)

                        = 40 units

Answer:

18

Step-by-step explanation:

You can multiply 9 x 2 like normal to get 18. Then you look at the signs. They are both negative, meaning their product is positive, making the answer 18.

Answer:

521, 400

Step-by-step explanation:

with the 1cm= 100m scale

6.6cm= 660m

7.9cm=790m

so the area would be 660×790

which is 521,400 meters squared

Answer:

Average Rate of change = 2

Step-by-step explanation:

Given - A rabbit hops 8 meters in one second. After 7 seconds, the rabbit has hopped 20 meters.

To find - What is the rabbit's average rate of change?

Formula used -

Average rate of change of a function f(x) in an interval [a, b] is [tex]\frac{f(b) - f(a)}{b - a}[/tex]

Proof -

Given that,

In 1 second - Rabbit hoops 8 meters

In 7 seconds - Rabbit hoops 20 meters

So,

Average Rate of change = [tex]\frac{20 - 8}{7 - 1}[/tex]

                                         = [tex]\frac{12}{6}[/tex]

                                         = 2

⇒Average Rate of change = 2

Answer:

Bar Chart

Step-by-step explanation:

The Bar graph is has immense capability in the aspect of data visualization. It is capable of grouping data into different categories, such as in the scenario above, where fishes are grouped based on species. These groups are then represented as vertical bars displaying the number of these species of fish. With this we can make comparison and inferences regarding the maximum, minimum and other summary statistics about the distribution.

Answer:

f'(x) = 6/x

Step-by-step explanation:

1. Use logarithm rules to move the power to the front so ln(x)^6 becomes 6 ln(x).

2. Differentiate ln(x) which is always 1/x

3. multiply 1/x by the 6

6/x

Answer:

options?

Step-by-step explanation:

It would be any number that is less than 16 because starting with the original question:

x-6>10

By canceling out the -6:

x-6+6 > 10+6

x > 16

Answer:

14 weeks.

Step-by-step explanation:

160/12= 13.8

13 weeks earns her $158

14 weeks earns her $160. So the fewest number of weeks she needs is 14.

Answer:

b) H0:μ=90, H1:μ≠90

Step-by-step explanation:

The corporation wants to know if the mean number of days is different from the 90 days claimed.

This means that at the null hypothesis, we test if the mean number is the claimed value of 90, and so:

[tex]H_0: \mu = 90[/tex]

The corporations wants to know if the mean number is different, and thus, at the alternate hypothesis, we test if the mean number is different from 90, that is:

[tex]H_1: \mu \neq 90[/tex]

This means that the correct answer is given by option b.

Answer:

Solution given:

principal [P]=P

time [T]=4 years

Rate [R]=13%

compound amount=18900

Simple interest=P-18900

we have

simple interest=[tex] \frac{P*T*R}{100} [/tex]

P-18900=[tex] \frac{P*4*13}{100} [/tex]

100P-1890000=52P

48P=1890000

P=1890000/48

P=39375

the sum that amounts =Rs 39375

Answer:

Mrs. Hanson should order about 2.5 times as many crew neck shirts as raglan shirts.

Step-by-step explanation:

Answer:

35%

Step-by-step explanation:

This is simple, just use the formula: Number1 / Number 2 x 100 when you use it it will look like: 56/160x100 which 56/100 is 0.35 and 0.35x100 is 35%

Answer:

(3d+3) + (3d+3)

Step-by-step explanation:

Answer:

a.The estimate is 43/60

b.No, he should not change the estimate based on this information

Step-by-step explanation:

The estimate he would make is dividing the number of bricks which he sees as green by the total number of bricks. That would be the probability of selecting a green brick out of all the 60 bricks.

Mathematically this probability is 43/60

No, Andre should not change his estimate.

The reason is that we are only told that she looked in the bag and saw 6 bricks, we do not know whether the kind of bricks he saw were green in color. The only time it is necessary for Andre to change his estimate is when it is confirmed that the six bricks seen by Mai in the bag were essentially confirmed to be green. without this confirmation, the estimate should not be changed.

Answer:

8.3 feet.

Step-by-step explanation:

Area = (h/2)(a + b)   where h = height and a and b are the lengths of the 2 bases.

70.55 = (h/2)(11.4 + 5.6)

(h/2)(17) = 70.55

h/2 = 70.55/17

h = (2 * 70.55) / 17

h = 8.3 feet.

Answer:

x = 88

Step-by-step explanation:

Becuase this is a quadrilateral,  the opposite angles total 180 degrees. So, the opposite of x is 92. That would mean that x + 92 = 180. We subtract 92 from both non-variable sides to get the x by itself. 180 - 92 = 88. 92 - 92 = 0. this leaves us with X = 88
