Answer 1

Answer:

Step-by-step explanation:

When tossing a coin, there are two possibilities, heads or tails, thus one can rule out the first option. When rolling a pyramid-die, then there are four different possibilities, each one with an equally likely chance, and each one's outcome is non-dependant on the outcome of the coin toss. Thus options (B) and (C) can be ruled out. Therefore, option (D) is the only remaining valid option.

How many different possible outcomes are there if you roll a four-sided die in the shape of a pyramid twice?

Answers

Answer:

Step-by-step explanation:

sixteen possible outcomes

A fair 4-sided die is rolled twice and we assume that all sixteen possible outcomes are equally likely.

The number of possible outcomes on rolling a four sided die twice is 16.

What is probability?

Probability deals with the occurrence of a random event. The chance that a given event will occur. It is the measure of the likelihood of an event to occur.The value is expressed from zero to one.

For the given situation,

A four-sided die in the shape of a pyramid is rolled twice.

The possible outcomes are

{ [tex](1,1),(1,2),(1,3),(1,4)[/tex]

[tex](2,1),(2,2),(2,3),(2,4)[/tex]

[tex](3,1),(3,2),(3,3),(3,4)[/tex]

[tex](4,1),(4,2),(4,3),(4,4)[/tex] }

Hence we can conclude that the number of possible outcomes on rolling a four sided die twice is 16.

The sum of the ages of two brothers is 31years and the difference of their ages is 5 years.find their present ages.

Answers

Answer:

13 years

18 years

Step-by-step explanation:

Let the age of the two brothers be x and y years.

According to the first condition:

x + y = 31.....(1)

According to the first condition:

x - y = 5.....(2)

Adding equations (1) & (2)

x + y = 31

x - y = 5

_______

2x = 36

x =36/2

x = 18 years

Plug x = 18 in equation (1)

18 + y = 31

y = 31 - 18

y = 13 years

Verification:

13 + 18 = 31

18 - 13 = 5

Jonah and Graham are working together. Jonah claims that (x+y)^2 = x^2+y^2. Graham is sure Jonah is wrong, but he cannot figure out how to show it. a.) Help Graham find as many ways as poissible to convince Jonah that he is incorrect. How can he rewrite (x+y)^2 correctly?

Answers

Answer:

Here is what I got hope it helps!!!!!!!

Step-by-step explanation:

Equivalent expressions are expressions with the same value.

The proper way to rewrite the equation is: [tex]\mathbf{(x + y)^2 = x^2 + 2xy + y^2 }[/tex]

Jonah's equation is given as:

[tex]\mathbf{(x + y)^2 = x^2 + y^2}[/tex]

To convince Jonah that Jonah's equation is wrong, Graham can do any of the following

Assume values for x and yExpand the equation

Assume value for x and y

Let x = 2 and y = 4

[tex]\mathbf{(2 + 4)^2 = 2^2 + 4^2}[/tex]

[tex]\mathbf{36 = 20}[/tex]

The above equation is false.

So, it means that: [tex]\mathbf{(x + y)^2 \ne x^2 + y^2}[/tex]

Expand the equation

We have:

[tex]\mathbf{(x + y)^2 = x^2 + y^2}[/tex]

Open the bracket

[tex]\mathbf{x^2 + 2xy + y^2 = x^2 + y^2}[/tex]

Cancel out common terms

[tex]\mathbf{2xy = 0}[/tex]

The above equation is false.

So, it means that: [tex]\mathbf{(x + y)^2 \ne x^2 + y^2}[/tex]

The proper way to rewrite the equation is:

[tex]\mathbf{(x + y)^2 = x^2 + 2xy + y^2 }[/tex]

A bakery buys a large bag of sugar that has 34 cups. They use 10 cups to make some cookies. They use the rest of the bag to make 144 giant muffins. Their customers want to know how much sugar is in each muffin.

Answers

Answer:

there would be 1 ÷ 6 sugar in each month

Step-by-step explanation:

The computation of the customers that want to know the sugar in each muffin is shown below

Here we assume the sugar in each muffin be x

Now there is 30 cups and 10 cups should be used for making some cookies

And, the rest would be use for making 144 gaint muffins

So, the equation that should be used is

10 + 144x = 34

144x = 24

x = 1 ÷ 6

So there would be 1 ÷ 6 sugar in each month

Lisa, Juan and isaac equally shared 1/2 of a cake which fraction of the whole cake did each of them recieve

Answers

Answer:

Each will receive [tex]\frac{1}{6}th[/tex] of the cake.

Step-by-step explanation:

Let the amount of cake = c

Lisa, Juan and Isaac are the persons who are sharing half of a cake equally.

Number of persons = 3

Part of the cake shared = [tex]\frac{c}{2}[/tex]

Fraction of the cake shared by each = [tex]\frac{\text{Amount of cake shared}}{\text{Number of persons who shared}}[/tex]

= [tex]\frac{\frac{1}{2}c}{3}[/tex]

= [tex]\frac{1}{6}c[/tex]

Therefore, fraction of total cake shared by each member will be [tex]\frac{1}{6}[/tex] of the total amount of cake.

Answers

Answer: $8 to $12

Step-by-step explanation:

The ticket prices range from $10 to $15 so the new range will see these two figures reduced by 20%.

$10 after the discount:

= 10 * (1 - 20%)

Researchers in education are performing a study to see if listening to soothing music while taking a standardized math test increases the mean test score. The hypotheses are H 0 : mu=79 versus H a : mu>79 , and the p-value for the hypothesis test was 0.035.

At the 5 % significance level , what should the researchers conclude?

1. There is sufficient evidence to conclude that listening to soothing sounds increases the mean test score.

2. There is sufficient evidence to conclude that listening to soothing sounds decreases the mean test score.

3. There is insufficient evidence to conclude that listening to soothing sounds decreases the mean test score.

4. none of the above

Answers

Answer:

1. There is sufficient evidence to conclude that listening to soothing sounds increases the mean test score.

Step-by-step explanation:

A p - value less than 0.05 means that the test hypothesis is false or rejected.

In this question the test hypothesis is H 0 : mu=79 which is false as p-value is 0.035.

Whenever the p- value is less than the significance level H0 is rejected.

Hence the null hypothesis is rejected.

Therefore only choice 1 is correct.

There is sufficient evidence to conclude that listening to soothing sounds increases the mean test score.

There is sufficient evidence to support the claim.

A True Victory Kelso and his best friend, Adiel, had spent weeks building their go-cart for the annual Wolf Club go-cart race. Then, at the last minute, another team's go-cart broke down. Adiel and Kelso decided to let that team use their go-cart. But now they were regretting their decision. It was painful watching the race from the sidelines. When the first cart crossed the line, Adiel and Kelso couldn't helping wondering how it would have felt if they had won. Within seconds, other carts raced by. Instead of feeling glum, Kelso began to laugh. He delighted in the breeze that blew through his hair as the go-karts rushed past. Adiel noticed a genuine smile spread wide across Kelso's face. Adiel realized that this sense of happiness was also surging throughout his body, even though he had not raced. "You did a really nice thing today," whispered a nearby Wolf Club leader. "Thanks," said Adiel. "I guess I won't ever know if I could've won the race." "Well winning isn't one of the Wolf Club mottos," said the leader. "But we do believe that we should promise to do our best and do something good for somebody every day. I'd say you proved yourself today as one of the worthiest people here to be called a Wolf Cub."
