All of the equations that are true include the following:

B. 56 + 70 = 14(4 + 5).

C. 28 + 49 = 7(4 + 7).

What is the distributive property of multiplication?

In Mathematics, the distributive property of multiplication states that when the sum of two (2) or more addends are multiplied by a particular numerical value, the same result and output would be obtained as when each addend is multiplied respectively by the same numerical value, and the products are added together.

How to determine the true equation?

In order to determine the true equation, we would apply the distributive property of multiplication and then check whether or not the right-hand side is equal to the left-hand side.

By applying the distributive property of multiplication to the given mathematical expression, we have the following:

32 + 96 = 8(4 + 14)

32 + 96 = 32 + 112 (False).

56 + 70 = 14(4 + 5).

56 + 70 = 56 + 70 (True).

28 + 49 = 7(4 + 7).

28 + 49 = 28 + 49 (True).

27 + 36 = 3(9 + 13)

27 + 36 = 27 + 39 (False).

25 + 35 = 5(5 + 6)

25 + 35 = 25 + 30 (False).

A manufacturer of all-in-one printers is concerned that the warranty costs for a particular printer model exceed the amount expected by the company. Based on a review of completed warranty claims, the distribution of the warranty cost per claim is skewed to the right with mean $150 and standard deviation $50. A random sample of 25 completed warranty claims is selected, and the sample mean cost is recorded. Suppose the process of selecting a random sample of 25 completed warranty claims and recording the sample mean cost is repeated for a total of 100 samples. Which of the following best describes a dotplot created from the 100 sample means?
(A) The dotplot has the same shape as the distribution of the population with mean $150 and standard deviation $25.
(B) The dotplot has the same shape as the distribution of the population with mean $150 and standard deviation $50.
(C) The dotplot has the same shape as the distribution of the population with mean $150 and standard deviation $100.
(D) The dotplot is closer to approximately normal than the distribution of the population with mean $150 and standard deviation $10.
(E) The dotplot is closer to approximately normal than the distribution of the population with mean $150 and standard deviation $50.

Answers

Answer: D. The dotplot is closer to approximately normal than the distribution of the population with mean $150 and standard deviation $10.

Step-by-step explanation:

Based on the dotplot created from the 100 sample, the dotplot is closer to approximately normal than the distribution of the population with mean $150 and standard deviation $10.

The mean of the sampling distribution is just exactly like the population mean. On the other hand, the standard deviation will be: = 50/✓25 = 50/5 = 10

Therefore, the correct option is D.

Consider all five-digit numbers that can be created from the digits 0-9 0 - 9 where the first and last digits must be odd and no digit can repeat. What is the probability of choosing a random number that starts with 7 7 from this group? Enter a fraction or round your answer to 4 4 decimal places, if necessary.

Answers

There are a total of 5 digits that can be chosen for the first digit (1, 3, 5, 7, and 9), and 5 digits that can be chosen for the last digit (1, 3, 5, 7, and 9). Since no digits can repeat, the number of choices for the middle 3 digits is 9 * 8 * 7 = 504. Therefore, there are a total of 5 * 504 * 5 = 10,080 five-digit numbers that can be formed from the digits 0-9 where the first and last digits are odd and no digit can repeat.

Of these numbers, there are 504 numbers that start with 7, because there are 504 choices for the middle 3 digits and 1 choice for the first digit. Therefore, the probability of choosing a random number that starts with 7 from this group is 504 / 10,080 = 0.05, or approximately 5%.

How to solve the expression?

Here we want to solve the following expression:

(3 + 5)*5 - 20*(2 + 5)

The first thing that you need to solve when working in these type of problems, are the operations inside the parenthesis, then we will get:

(3 + 5)*5 - 20*(2 + 5) = (8)*5 - 20*(7)

Now we need to solve the two products, we will get:

(8)*5 - 20*(7) = 40 - 140 = -100

The number of boys and girls in a class are in the ratio 7:5. The number of boys is 8 more than the number of girls. What is the total class strength? *​

Answers

Answer:  48 students total

======================================================

Explanation:

If there were 7 boys and 5 girls, then we'd have the ratio of 7:5. The boys are listed first because of how your teacher mentions boys first to set up the ratio. The order is important. That means 7:5 is different from 5:7.

With 7 boys and 5 girls, we see that there are 7-5 = 2 more boys compared to girls, and not 8. The jump from 2 to 8 is "times 4", which means we'll need to multiply each gender count by 4 to get to the class size we want

boys: 7 ---> 7*4 = 28

girls: 5 ---> 5*4 = 20

Having 28 boys and 20 girls will lead to the ratio 28:20, and it reduces fully to 7:5 when we divide both parts by the GCF 4.

The total number of students is 28+20 = 48

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

Here's another way we can solve.

x = number of girls

x+8 = number of boys, since there are 8 more

The ratio of boys to girls is 7:5, meaning,

(number of boys)/(number of girls) = 7/5

(x+8)/x = 7/5

(x+8)*5 = x*7 .... cross multiply

5x+40 = 7x

40 = 7x-5x

40 = 2x

2x = 40

x = 40/2

x = 20

There are x = 20 girls and x+8 = 20+8 = 28 boys. So 20+48 = 48 total.

A pipe has 9/16" that is threaded, but you need to trim 4/32" off of the threaded part. How long will the threaded be after the trim? a. 17/32, b. 7/8, c. 7/16, d/ 15/32

Answers

To find the answer, we can begin by converting 9/16 to a denominator of 32. This can be done by multiplying everything by 2:

9 • 2 = 18
16 • 2 = 32

Our new fraction is 18/32. Now to subtract:

18/32 - 4/32 = 14/32

With our new fraction, we can divide the numerator and denominator by 2 to find that:

18/32 - 4/32 = 7/16

Hence, our final difference is option C.

What is volume?

In three dimensions, everything takes up some space. What is being measured here is the area's volume. The volume of an object is the area occupied inside its three-dimensional boundaries. It is referred to as the object's capability on occasion.

The amount required to fill an object can be determined by finding its volume, for example, how much water is required to fill a bottle, aquarium, or water tank.

Given

dimensions of box 20 x 13 x 12, 12 x 12 x 12 and 20 x 10 x 6

volume of box 1 = 20 x 13 x 12 = 3120 cubic inches

volume of box 2 = 1728 cubic inches

volume of box 3 = 20 x 10 x 6 = 1200 cubic inch

oranges in box 1 = 96

oranges in box 2 = 53

oranges in box 3 = 37

and radius of  orange  = 32./2 = 1.6 inches

volume of each orange = 4/3πr³

volume of each orange = 4/3(3.14)(1.6)³

volume of each orange = 4/3(3.14)(4.096)

volume of each orange =  17.14 cubic inches

here one orange will cover 17.14 cubic inches.

7. let the dimension of box is 15 x 12 x 16

volume of box is = 15 x 12 x 16 = 2880 cubic inches

the number of oranges in box will be 2880/17.14 = 168 oranges

Hence there will be 17.14 cubic inch per orange volume is covered, and 168 oranges will be in box for given dimensions.

Answers

Answer:

Find answers below.

Step-by-step explanation:

The equation isn't explicitly stated or well written. Thus, we would assume two (2) case scenario for the equation of line by altering the signs.

Scenario 1;

y = 9 + x

Mathematically, the equation of a line is given by the formula;

Equation of straight line is y = mx + c

Where;

m is the slope.

x and y are the points

c is the intercept.

Comparing the two equations, we have;

y = mx + c = 9 + x

Constant, c = 9

Slope, m = 1

Scenario 2.

y = 9 - x

y = mx + c = 9 - x

Constant, c = 9

Slope, m = -1

Based on the experiment if a card is chosen 200 times how many times would you expect to pick a card without stripes?

Answers

The number of expected times to pick a card without strips is 130.

What is a percentage?

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

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,

The percentage of stripes from the 120 times.

= 42/120 x 100

= 35%

Now,

Based on this experiment,

The number of strip cards out of 200 times.

= 35% of 200

= 35/100 x 200

= 35 x 2

= 70

The number of times to pick a card without strips.

= 200 - 70

= 130

Thus,

The expected number of times to pick a card without stripes is 130.

Bonaly is one of the most decorated individuals in womens figure skating. She won medals in nearly every competition she entered. Bonaly did not start out as many young figure skaters do. For example, instead of learning to ice skate at a young age, Bonaly got her start in gymnastics. From the beginning, she showed promise as she began winning competitions for her tumbling routines. Her excellence and competitiveness paid off when, at the age of twelve, she won the World Championship in tumbling. From there, Bonaly turned her energies to ice-skating. Even at that young age, she was getting a late start in a sport that many skaters begin as early as age four. However, her strong gymnastics background helped fuel Bonaly's quick and early successes in competitive figure skating.Bonaly soon earned praise for her powerful and athletic performances. Her fierce determination to win was noted. Bonaly was a strong skater, performing extremely difficult moves and landing them consistently. However, she soon found herself battling against strongly held stereotypes of what a womens figure skater was supposed to be. This included ideas of a cool and aloof ice princess or as cute as a buttona perky ballerina on ice skates. To set herself apart, Bonaly chose to wear bold and bright costumes instead of the pastel colors favored by other female skaters. It was also suggested by some that because she was black and did not fit the typical womens ice skater model, Bonaly was judged more harshly than the other competitors. Bonaly felt she had to do more than any other competitor to be accepted and, perhaps even more importantly, win. Her growing perceptions of a double standard became even more visible during the 1994 World Championships in Japan. Bonaly earned a silver medal, losing to Japans Yuka Sato. A visibly upset Bonaly claimed that her routine was far more difficult than Satos. She not only refused to stand on the second place winners spot at the podium but also removed her silver medal from around her neck. Some say that she behaved poorly. To that, Bonaly responded, When you do sport, the rule is that you're supposed to play fair, to be a good athlete and good sport, I get it,""But I think at this point it was more an act of saying, 'OK, this is too much.' It happened many years in a row."Bonaly is probably most famous for a bold and daring stunt she performed during the 1998 Olympic Games held in Nagano, Japan. By this time, Bonaly was a clearly established skating champion; she had already won numerous honors for her skating, including winning the French Nationals nine times, as well as being a five-time European champion. She was also a three-time world silver medalist. The Nagano Olympics was Bonalys third time at the international winter sports competition. But she entered the games during a period when her skating performances that year were weaker than usual, due to an ongoing heel injury. The extent of Bonalys injury was reflected in her low scores. She realized that she would not earn a medal. So, she decided to do something special in her last routine, the freestyle skate. The something speciala backflipwas a feat she was already known for. It had already gotten her into trouble as the jump was banned by Olympic officials because of the danger. But, knowing that this would be her last Olympics, Bonaly decided to please the crowd and not the judges. In the middle of her routine, Bonaly abandoned her planned triple Lutza jump combined with three spinsand instead threw her arms overhead to do the back flip, landing successfully on one skate. Bonaly landed her flip cleanly and finished her program with no mistakes. The crowd went wild with applause and cheers.Although her feat did not win her a medal, it was a move that, given its risk and difficulty, made people remember her. Twenty years later, people who saw this famous jump still talk about it. Bonaly remains the only female skater in history to do this jump successfully in competition. Although still illegal to perform in Olympic competition, the flip has now been named The Bonaly. Bonaly will also be remembered for being a strong and outspoken woman of color in a sport that traditionally has few minorities. Her willingness to challenge traditional expectations for young female figure skaters has shown others that there are many different paths to success.
