Answer:

BAKING TINS

Step-by-step explanation:

Use the Pythagorean Theorem to solve = \(a^{2} +b^{2} = c^{2}\).

2) 8² + 6² = c²

64 + 36 = 100

\(\sqrt{100}\)

x = 10 = I

3) 10² - 9² = a²

100 - 81 = 19

\(\sqrt{19}\)

x = 4.4 = G

4) 8.8² + 3.2² = c²

77.44 + 10.24 = 87.9

\(\sqrt{87.9}\)

x = 9.4 = B

5) 27² - 24² = a²

729 - 576 = 153

\(\sqrt{153}\)

x = 12.4 = S

6) 11² - 7² = a²

121 - 49 = 72

\(\sqrt{72}\) = 8.5

13² + 8.5² = c²

169 + 72.25 = 241.25

\(\sqrt{241.25}\)

x = 15.5 = T

7) 22.1² + 14.2² = c²

488.41 + 201.64 = 690.1

\(\sqrt{690.1}\)

x = 26.3 = K

8) 32² + 41² = c²

1024 + 1681 = 2705

\(\sqrt{2705}\)

x = 52 = N

Answer:

choice D

Step-by-step explanation:

Answer:

\(-\frac{15}{4}\)

Step-by-step explanation:

To find the slope or the gradient of a line you have to utilise the formula

\(\frac{y2-y1}{x2-x1}\)

Y₂ = -7

Y₁ = 8

X₂ = 7

X₁ = 3

So,

\(\frac{-7-8}{7-3}\)

→ Simplify

\(-\frac{15}{4}\)

By using the given points, we will see that the slope is -15/4.

If we know that a given line passes through two known points (x₁, y₁) and (x₂, y₂), then the slope can be written as:

\(s = \frac{y_2 - y_1}{x_2 - x_1}\)

Here the line passes through the points (3, 8) and (7, -7).

Using the above formula, we can see that the slope is:

\(s = \frac{-7 - 8}{7 - 3} = \frac{-15}{4}\)

Two years ago, Salim's age was S - 2, and his daughter's age was D - 2. At that time, Salim was thrice as old as his daughter, so:
S - 2 = 3(D - 2)
In six years, Salim's age will be S + 6, and his daughter's age will be D + 6. At that time, Salim will be four years older than twice her age, so:
S + 6 = 2(D + 6) + 4
Now, we have a system of two equations with two variables:
1) S - 2 = 3(D - 2)

2) S + 6 = 2(D + 6) + 4

Let's start by assigning variables to the ages of Salim and his daughter. We can use "S" for Salim's age and "D" for his daughter's age.

From the first sentence of the problem, we know that two years ago, Salim was three times as old as his daughter:

S - 2 = 3(D - 2)

Simplifying:

S - 2 = 3D - 6
S = 3D - 4

Now we need to use the second sentence of the problem. In six years, Salim will be four years older than twice his daughter's age:

S + 6 = 2(D + 6) + 4

Simplifying:

S + 6 = 2D + 16
S = 2D + 10

We have two equations for S in terms of D, so we can set them equal to each other:

3D - 4 = 2D + 10

Subtracting 2D from both sides:

D - 4 = 10

Adding 4 to both sides:

D = 14

So Salim's daughter is currently 14 years old.

We can use either equation we found for S to solve for Salim's age:

S = 3D - 4 = 3(14) - 4 = 38

So Salim is currently 38 years old.

Therefore, Salim is older than his daughter by 24 years (38 - 14), and two years ago he was three times as old as she was (36 and 12). In six years, Salim will be 44 and his daughter will be 20, and he will be four years older than twice her age.

The correct answer is option C, when the distribution of the data is approximately symmetric and bell-shaped.

According to the Empirical Rule, also referred to as the 68-95-99.7 Rule, for a normal distribution, roughly 68% of the data will lie within one standard deviation of the mean, 95% of the data will lie within two standard deviations of the mean, and 99.7% of the data will lie within three standard deviations of the mean.

Only when the distribution of the data is symmetric and bell-shaped does this rule hold.

The Empirical Rule cannot be used to estimate percentages if the data is skewed to the left or right.

The Empirical Rule can be used to predict the population from which the data were taken, making it a useful tool when examining data with a normal distribution.

It's crucial to remember that this rule is merely an estimation and may not be correct depending on whether the data follows a normal distribution.

Answer:

$180

Step-by-step explanation:

First, you have to calculate the amount that Olivia would have paid at the end of the loan which would be the result of multiplying her monthly payment for the number of payments:

Total payment= $308*(12*5)

Total payment= $308*60

Total payment= $18,480

Then, you have to calculate the amount that Garrett would have paid at the end of the loan:

Total payment= $311*(12*5)

Total payment= $311*60

Total payment= $18,660

Now, you have to calculate the difference in the amount Olivia and Garrett would have paid:

$18,660-$18,480= $180

According to this, an $18,000 loan will cost Garrett $180 more than Olivia.

8x = -27, or x = -27/8

Answer:

There were 60 kids in class.

Step-by-step explanation:

Since the kids had two choices and the ratio between them was for every 3 children that selected "Shin Chan" only 1 selected "Tom and Jerry", then in order to calculate the number of children in the class if 45 kids selected "Shin Chan", we first need to calculate the number of children that selected the other option. To do that we divide the number by 3. We have:

children(Tom and Jerry) = children(Shin Chan)/3

children(Tom and Jerry) = 45/3 = 15

Therefore the number of children in the class is:

children(class) = children(Tom and Jerry) + children(Shin Chan)

children(class) = 15 + 45 = 60

There were 60 kids in class.

By using the given information about the inverse relation, we will get:

First, we know that y varies indirectly with x, then we can write the relation as:

y = k/x.

Where k is a constant.

Then, we know that when y = 7, we have x = -4.

Replacing these we can find the value of k:

7 = k/(-4)

7*(-4) = k = -28

Then the relation between x and y is:

y = -28/x.

Now, we want to find the value of y when x = 2, then we just replace that in the above equation:

y = -28/2 = -14

The data support the researcher's claim that the current ozone level is not at a normal level, at the 0.05 level of significance, concluded with the help of a one-sample t-test.

To test whether the current ozone level is significantly different from the normal level of 5.5 ppm, we can use a one-sample t-test.

The null hypothesis is that the mean ozone level is equal to 5.5 ppm:

H0: mu = 5.5

The alternative theory is that the average ozone level exceeds 5.5 ppm:

Ha: mu > 5.5

The significance threshold will be set at 0.05.

t = (x - mu) / (s / sqrt(n)) is the test statistic for a one-sample t-test.

where x is the sample mean, is the hypothesized population mean, s represents the sample standard deviation, and n represents the sample size.

When we substitute the provided values, we get:

t = (6.0 - 5.5) / (0.9 / sqrt(13)) = 1.936

Using a t-table with 12 degrees of freedom (n-1=13-1=12) and a significance level of 0.05, the critical value is 1.782. Since our calculated t-value (1.936) is greater than the critical value (1.782), we reject the null hypothesis.

Therefore, we can conclude that the data support the researcher's claim that the current ozone level is not at a normal level, at the 0.05 level of significance.

The probability of having 7 boys in a family with 7 children is 1 out of 128, as there is only one favorable outcome out of 128 total possible outcomes.

To find the probability, we need to calculate n(E) and n(S).

In this case, event E represents the scenario where all 7 children are boys. The sample space S consists of all possible permutations of boys and girls for the 7 children, which is 2^7 = 128.

This is because each child has 2 possibilities (boy or girl), and we multiply these possibilities for all 7 children.

Since event E includes only one specific outcome (all boys), n(E) is equal to 1. Therefore, both n(E) and n(S) are 1 and 128, respectively. The probability of having 7 boys is given by n(E)/n(S) = 1/128.

True. In a regression model, the dependent variable is the variable that we aim to predict or explain using one or more independent variables.

In a regression model, the dependent variable is indeed the variable that we aim to predict or explain. It represents the outcome or response variable that we are interested in understanding or analyzing. The purpose of the regression analysis is to examine the relationship between this dependent variable and one or more independent variables. By identifying and quantifying the influence of the independent variables on the dependent variable, regression analysis allows us to make predictions or explanations about the behavior or value of the dependent variable.

The regression model estimates the relationship between the variables based on observed data and uses this information to infer how changes in the independent variables impact the dependent variable.
