Answer 1

Answer:

<b = 23°

Step-by-step explanation:

<a and <b are complementary so they add up to 90

<a + <b = 90

Where <a = 67

67 + <b = 90

<b = 90 - 67

<b = 23°

Answer 2

Answer:

∠b=23°

Step-by-step explanation:

∠a+∠b=90°

67°+∠b=90°

Subtract 67° from both sides

∠b=23°

A basket contains 3 apples and 7 oranges. A fruit is drawn and put back into the basket. This process is repeated 3 times. What is the probability that selected three fruits are orange? **Please answer in fractions only!**

Answers

Answer:

343/1000 or 0.343

Step-by-step explanation:

Given: A basket contains 3 apples and 7 oranges. A fruit is drawn and put in the basket. This process is repeated 3 times.

To find: The probability that selected three fruits and oranges.

Solution:

\(\frac{7}{3+7}\) \(=\frac{7}{10}\)

Now for 3 times, the probability

= \(\frac{7}{10} *\frac{7}{10}*\frac{7}{10}\)

\(=0.343\)

Answer:

27/343

Step-by-step explanation:

Probability one = 3/7

3 times = 3/7*3/7*3/7

A box contains several copies of Mrs. Spencer's new pamphlet. The box weighs 2,000 grams. This chart

Answers

Answer:

This example represents discrete data.

Step-by-step explanation:

Discrete data refers to information that can only take certain specific values. In this case, the number of pamphlets added to the box (x) can only take on integer values such as 0, 1, 2, 3. Similarly, the effect on the box's weight (y) is also given as specific values: 0, 6, 12, 18.

In contrast, continuous data would involve measurements that can take any value within a range, such as height, weight, or temperature.

Since the number of pamphlets added and the corresponding effect on the box's weight are presented as specific, separate values, the data in this example is considered discrete.

This is an example of discrete data

A. 1607.7

First we start with the formula for cylinders v=(pi)r(squared)h filled in Thats v=(3.14)(8 squared) (8) which brings us to the answer 1607.68 but you must round to the nearest tenth aka 1607.7
please help me i will give brainliest to first person to anwser.

Answer:

The first option, V ≈ 1607.7 in²

Step-by-step explanation:

Find the volume of the given cylinder.

\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)

Given:

r = 8 in

h = 8 in

π = 3.14

Find:

V = ?? in³

\(\hrulefill\)

Now solving,

Substitute the given values into the formula:

=> V = (3.14)(8)²(8)

Using a calculator to simplify:

=> V = 1607.68 in²

Rounded to the nearest tenth:

∴ V ≈ 1607.7 in²

Thus, the first option is correct.

Data was collected on the amount of time that a random sample of 8 students spent studying for a test and the grades they earned on the test. A scatter plot and line of fit were created for the data.

scatter plot titled students' data, with points plotted at 1 comma 80, 2 comma 70, 2 comma 80, 2 comma 90, 3 comma 80, 3 comma 100, 4 comma 90, and 4 comma 98, and a line of fit drawn passing through the points 0 comma 70 and 1 comma 75

Find the y-intercept of the line of fit and explain its meaning in the context of the data.

80; a student who studies for 0 hours is predicted to earn 80% on the test
70; a student who studies for 0 hours is predicted to earn 70% on the test
10; for each additional hour a student studies, their grade is predicted to increase by 10% on the test
5; for each additional hour a student studies, their grade is predicted to increase by 5% on the test

Answers

Answer:

Step-by-step explanation:

The y-intercept of the line of fit is 70, which means that a student who does not study at all (0 hours) is predicted to earn a grade of 70%. In other words, the line of fit starts at the point (0,70), indicating that even if a student does not study at all, they can still earn a grade of 70% on the test. However, it should be noted that this prediction may not always hold true for all students and situations. The y-intercept provides a useful reference point for interpreting the rest of the data, and helps to establish a baseline for the relationship between study time and test grades.
