state the given statements is true or false. If areas of two rectangles are the same, then they are congruent
Answers
Hey there!
This answer to your question is it is false.
This is because you could have a rectangle with a length of 6 and a width of 4, and the area would be the same as a rectangle with a length of 8 and a width of 3. They would both be 24.

Find the measure of the acute angle that line y=1/3x+4 makes with a horizontal line. Round your answer to the nearest tenth.
Also, I hope you are having a good day.
Answers
Answer:
The measure of the acute angle is 18.4°
Step-by-step explanation:
The angle between a line of equation y = m x + b and the positive part of the x-axis is Ф = [tex]tan^{-1}[/tex](m), which means tan Ф = m, where m is the slope of the line
Let us use this rule to solve the question
∵ A line of equation y = [tex]\frac{1}{3}[/tex] x + 4 makes with a horizontal line an acute ∠
→ Compare the equation of the line by the form of the equation above
∴ m = [tex]\frac{1}{3}[/tex]
→ Assume that the acute angle is Ф
∴ The acute angle between the line and the horizontal line is Ф
→ By using the rule above
∵ tan Ф = m
∴ tan Ф = [tex]\frac{1}{3}[/tex]
→ Use [tex]tan^{-1}[/tex] to find Ф
∵ Ф = [tex]tan^{-1}[/tex] ( [tex]\frac{1}{3}[/tex] )
∴ Ф = 18.43494882
→ Round it to the nearest tenth
∴ Ф = 18.4°
∴ The measure of the acute angle is 18.4°
which value for the constant c makes z =-5/4 an extraneous solution in the following equation?
[tex] \sqrt{4z + 9} = cz + 8[/tex]
Answers
Answer:
c=8
Step-by-step explanation:
The value of c that makes z = -5/4 an extraneous solution is c = 24/5.
What is the Linear equation?A linear equation is defined as an equation in which the highest power of the variable is always one.
The equation is given as:
√{4z + 9} = cz + 8
An extraneous solution is a solution that is not a valid solution to the original equation, but it is obtained during the process of solving the equation. In this case, the extraneous solution is z = -5/4.
To determine the value of c that makes z = -5/4 an extraneous solution, we can substitute -5/4 for z in the original equation. This gives us the following:
√{4 × -5/4 + 9} = -5/4 × c + 8
√{-5 + 9} = -5/4 × c + 8
√4 = -5/4 × c + 8
2 = -5/4 × c + 8
5/4 × c = 8 - 2
5/4 × c = 6
c = 6 × 4/5
c = 24/5
Therefore, the value of c that makes z = -5/4 an extraneous solution is c = 24/5.

A fuel injection system is designed to last 18 years, with a standard deviation of 1.4 years. What is the probability that a fuel injection system will last less than 15 years? 25% 33% 2% 20%
Answers
Answer:
2%
Step-by-step explanation:
We are given;
Standard Design mean; μ = 18
Sample design mean; x¯ = 15
Standard Standaed deviation; σ = 1.4
Let's find the test statistic from the formula;
z = (x¯ - μ)/σ
Thus;
z = (15 - 18)/1.4
z = -2.14
From the z-table attached, the p-value at z = -2.14 is 0.01618
Thus,
P(X < 15) = 0.01618
Converting to percentage, we have
P(X < 15) = 1.618%
This is approximately 2%
Using the normal distribution, it is found that there is a 2% probability that a fuel injection system will last less than 15 years.
Normal Probability DistributionIn a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.In this problem:
The mean is of 18 years, hence [tex]\mu = 18[/tex].The standard deviation is of 1.4 years, hence [tex]\sigma = 1.4[/tex].The probability that a fuel injection system will last less than 15 years is 1 subtracted by the p-value of Z when X = 15, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{15 - 18}{1.4}[/tex]
[tex]Z = -2.14[/tex]
[tex]Z = -2.14[/tex] has a p-value of 0.02.
0.02 = 2% probability that a fuel injection system will last less than 15 years.
