Given that y varies directly with x in the table, find the
value of y if the value of x is 5.
We know that this ratio is directly because the two magnitudes go up.
In this case we will get the proportionality constant by dividing any term of the second magnitude by the first.
For example:[tex]9 \: \div \: 3 \: = \: \boxed{3}[/tex]
Now that we know that k = 3, we can know how much "y" will be if x = 5.
We just multiply:

The support pole must be approximately 7.8 meters long.
What is the length of the support pole?
Based on all the information given in the statement, we prepare a geometric diagram that describes the system formed by the high-security fence and the support pole. The representation is attached below. Lastly, the length of the pole is found by using the law of sines:
l/sin 84° = 6 m /sin 50°
l = 6 m × (sin 84°/sin 50°)

39. Solve for x. SHOW ALL WORK FOR FULL CREDIT m n 6x-4 112°
Answer:
x = 12
Step-by-step explanation:
6x - 4 and 112 are same- side interior angles and sum to 180° , that is
6x - 4 + 112 = 180
6x + 108 = 180 ( subtract 108 from both sides )
6x = 72 ( divide both sides by 6 )
x = 12
Answer:
x = 12
Step-by-step explanation:
Consecutive Interior Angles Theorem
When a straight line intersects two parallel straight lines, the consecutive interior angles formed are are supplementary (sum to 180°).
Therefore:
⇒ 6x - 4 + 112 = 180
⇒ 6x + 108 = 180
⇒ 6x + 108 - 108 = 180 - 108
⇒ 6x = 72
⇒ 6x ÷ 6 = 72 ÷ 6
⇒ x = 12

Using traditional methods, it takes 103 hours to receive a basic driving license. A new license training method using Computer Aided Instruction (CAI) has been proposed. A researcher used the technique with 60 students and observed that they had a mean of 102 hours. Assume the variance is known to be 9. A level of significance of 0.01 will be used to determine if the technique performs differently than the traditional method. Find the value of the test statistic. Round your answer to 2 decimal places. Enter the value of the test statistic.
The test statistic based on the probability illustrated is -2.57.
How to calculate the probability?The basic training is given as 103 hours. The variance is also given as 9.
The test statistic will be:

What’s the volume of this cone?
volume = (1/3) * π * r² * h
= 1/3* 22/7 * (3.5*3.5) * 5 ( 22/7 is the value of π)
=64.1
Answer:
If you need a pi in your answer: 20.417 [tex]\pi[/tex] (rounded to the nearest thousanth)
If you don't: 64.141 (rounded to the nearest thousanth)
Step-by-step explanation:
The formula of the volume of a cone: [tex]V = \pi r^2\frac{h}{3}[/tex]
--> V = Volume, r = Radius, h = Height
In other words, the volume of the cone is the area of the circle x height x 1/3 x pi.
Since the radius of the cone is 3.5, you square that number.
--> (3.5)^2 = 12.25
The height is 5, so h/3 will be 5/3.
The volume = [tex]\pi[/tex] x 12.25 x 5/3

Let’ pretend that in an American city there were 2000 new cases on Monday which is a 12% decrease from two weeks ago.
1. Write a linear/exponential equation that
models this situation (consistent with the data
provided). Time is the explanatory variable, and
New Cases is the response variable.
B) Explain what the slope/multiplier (consistent
with your choice above) means in this context
of the problem. Be sure to use units.
The exponential equation of the model is A(t) = 2583 * 0.88^t and the multiplier means that the number of new cases in a week is 88% of the previous week
The function that models the dataThe given parameters are:
New, A(t) = 2000
Rate, r = 12%
The function is represented as:
A(t) = A * (1 - r)^t
So, we have:
2000 = A * (1 - 12%)^t
This gives
2000 = A * (0.88)^t
2 weeks ago implies that;
t = 2
So, we have:
2000 = A * 0.88^2
Evaluate
2000 = A * 0.7744
Divide by 0.7744
A = 2583
Substitute A = 2583 in A(t) = A * 0.88^t
A(t) = 2583 * 0.88^t
Hence, the exponential equation of the model is A(t) = 2583 * 0.88^t
The interpretation of the multiplierIn this case, the multiplier is 88% or 0.88
This means that the number of new cases in a week is 88% of the previous week

The average annual rainfall will be more than 40.6 inches in about 2.1 percent of the years.
What is the average annual rainfall?Generally, the equation for the probability is mathematically given as
[tex]P( X < x) = p( Z < x - \mu / \sigma)[/tex]
Therefore
[tex]P( X > x) = 0.021[/tex]
[tex]P( X < x ) = 1 - 0.021\\\\\p( X < x) = 0.979[/tex]
[tex]P( Z < x - \mu / \sigma) = 0.979[/tex]
The z score for the probability of 0.979 is 2.034, according to the table of z values.
[tex]x - \mu / \sigma \\\\x= 2.034[/tex]
In the given equation, replace the values of mu and sigma with their respective values, and then solve for x.

Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(3, 10) = 1. In the following intermediate step, it cannot further simplify the fraction result by canceling.
In other words - one half multiplied by three fifths is three tenths.
