Write a rational number in fraction form that is equivalent to -1/5
Answer & Step-by-step explanation:
You can find a rational fraction equivalent to [tex]-\frac{1}{5}[/tex] by multiplying the numerator and denominator by the same number. The number can be any:
[tex]-\frac{1}{5} *3\\\\-\frac{1}{5}*\frac{3}{3}=-\frac{3}{15}[/tex]
This works because if you simplify the new number, it will have the same value as the first fraction.
If you simplify both fractions to a decimal value, they both equal -0.2.
Confidence Interval: What is the 95% confidence interval to estimate the population mean?
Answer: The 95% confidence interval to estimate the population mean describes a range of values that a person can be 95% sure that it contains the population mean.
Step-by-step explanation:
A 95% confidence interval for population mean ([tex]\mu[/tex]) is an interval on which a person can be 95% confident that the true population mean lies in it.
i.e. The probability that it contains the true population mean is 95%.
i.e. P( Sample mean- margin of error < [tex]\mu[/tex] < Sample mean + margin of error) = 0.95.
Write an equation in slope-intercept form for the line with slope -3 and y-Intercept -2.
Answer:
y = -3x - 2
Step-by-step explanation:
Step 1: State what is known
Slope = m = -3
y-intercept = b = -2
Step 2: Substitute information into y = mx + b
y = (-3)x + (-2)
y = -3x -2
Therefore the equation in slop intercept form is y=-3x-2
Answer:
y = -3x-2Step-by-step explanation:
Replace m with -3, which is the slope replace b with -2, = y-intercept into the equation y=mx+b.
[tex]m = -3\\y - intercept = -2\\Slope\: intercept \: form :\\y =mx+c\\y = -3x-2[/tex]
Estimate and then solve the equation x-17 4/5=13 1/5

Step-by-step explanation:
the right triangular prism and the square rectangular prism both haven't had a 10 in in the same volume. A plane slices both solid parallel to their bases. The base of the triangular prism is a right triangle with legs 8 and 9 in Long. Find the length of the side of the square prism's cross-section in inches.
Answer: 6 inches
Step-by-step explanation:
Volume (V) = Area of the base (B) × height (h)
Both images have the same volume and the same height, therefore the Area of their bases must be equal to each other.
Area of the triangle
[tex]A=\dfrac{1}{2}\cdot b \cdot h\\\\.\quad=\dfrac{1}{2}\cdot 8 \cdot 9\\\\.\quad= 36[/tex]
Area of a square
A = s²
36 = s²
6 = s
1. How many percent of 50 is 10? 2. 20 Is 60% of what number?
Answer:
1. 20%
2. [tex]33.\overline{33}[/tex]
Step-by-step explanation:
We can use percentage proportions to find out these answers.
For number one, 10 is what percent of 50, we already know our two values so we can make the equation:
[tex]\frac{10}{50} = \frac{x}{100}[/tex]
Using the cross products property, we know that x is [tex](100\cdot10)\div50[/tex] which is 20.
So 10 is 20% of 50.
For number two, we know a different pair of two numbers now: we know the percent of x, and the percent it is, so the equation can become:
[tex]\frac{20}{x} = \frac{60}{100}[/tex]
Again, cross products property tells us that x is [tex](100\cdot20)\div60[/tex], which is [tex]33.\overline{33}[/tex].
Hope this helped!

How many pennies could you have if: When you break the pennies into groups of 2, you have 1 penny left over, AND when you break the pennies into groups of 3, you have 1 penny left over, AND when you break the pennies into groups of 5, you have 1 penny left over, AND when you break the pennies into groups of 7, you have NO pennies left over?
Answer:
91
Step-by-step explanation:
"When you break the pennies into groups of 2, you have 1 penny left over"
You have an odd number of pennies.
"when you break the pennies into groups of 3, you have 1 penny left over"
The number of pennies is one more than a multiple of 3.
"when you break the pennies into groups of 5, you have 1 penny left over"
A number that is divisible by 5 ends in 0 or 5. You have one more penny than that, so the number will end in 1 or 6. We already know the number is odd, so it cannot end in 6. The number of pennies must end in 1.
"when you break the pennies into groups of 7, you have NO pennies left over"
The number is a multiple of 7.
We need a multiple of 7 that ends in 1.
7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84, 91, ...
You could have 91.
When Mount Saint Helens erupted in 1980, the top of the mountain was blown off. A surveyor determined the height of the new summit by measuring the angle of elevation to the top to be 37°46'. She then moved 1000 feet closer to the volcano and measured the angle of elevation to be 40°30'. Find in ft the new height of Mount Saint Helens.
Answer:
Height= 8341.6 feet
Step-by-step explanation:
A surveyor determined the height of the new summit by measuring the angle of elevation to the top to be 37°46'. She then moved 1000 feet closer to the volcano and measured the angle of elevation to be 40°30'.
40°30'= 40.5°
37°46'= 37.767°
b = 180-40.5
b= 139.5°
a= 180-139.5-37.767
a= 2.733°
Using sine method
1000/Sina= y/sinB
1000/sin 2.733= y/sin 139.5
(1000*sin 139.5)/sin 2.733= y
(1000*0.6494)/0.04768= y
13619.96= y
Y= 13620 feet
Height/sin 37.767= 13620
Height=13620*sin37.767
Height= 8341.59
Height= 8341.6 feet

Answer:
56 + 6(n - 1)
Step-by-step explanation:
To know which of the equation represent the nth term, we simply test each equation to see the one that will satisfy the table given above.
This can be obtained as follow:
For 56 + 6(n - 1)
1. n = 2
56 + 6(n - 1) = 56 + 6(2 - 1)
= 56 + 6(1)
= 56 + 6
= 62
2. n = 5
56 + 6(n - 1) = 56 + 6(5 - 1)
= 56 + 6(4)
= 56 + 24
= 80
For 56 + 12(n - 1)
1. n = 2
56 + 12(n - 1) = 56 + 12(2 - 1)
= 56 + 12(1)
= 56 + 12
= 68
2. n = 5
56 + 12(n - 1) = 56 + 12(5 - 1)
= 56 + 12(4)
= 56 + 48
= 56 + 24
= 104
For 62 + 6(n - 1)
1. n = 2
62 + 6(n - 1) = 62 + 6(2 - 1)
= 62 + 6(1)
= 62 + 6
= 68
2. n = 5
62 + 6(n - 1) = 62 + 6(5 - 1)
= 62 + 6(4)
= 62 + 24
= 86
For 62 + 12(n - 1)
1. n = 2
62 + 12(n - 1) = 62 + 12(2 - 1)
= 62 + 12(1)
= 62 + 12
= 74
2. n = 5
62 + 12(n - 1) = 62 + 12(5 - 1)
= 62 + 12(4)
= 62 + 48
= 110
From the illustrations made above,
Only equation 56 + 6(n - 1) satisfied the table.
Therefore, the expression 56 + 6(n - 1) can be used to obtain the nth term.
Explain whether the function g(x) = x^9 + x^5 is borh an even function and an odd function.
A. The function g is both an odd and even function because it is a polynomial that passed through the origin
B. Although the function g is an odd function, it is not an even function because g(x) does not equal g(-x) for all x in the domain of the function.
C. Although the function g is not an even function, it is not an odd function because g(-x) does not equal -g(x) for all x in the domain of the function
D. The function g is neither an even nor odd function. The value of g(x) does not equal g(-x) for all x in the domain of the function, and g(-x) does not equal -g(x) for all x in the domain of the function.
Answer:

Find a12 given the geometric sequence 2, -6, 18, -54, ...
A. 1,062,882
B.-1,062,882
C. 354,294
OD. -354,294
Answer:
The answer is option AStep-by-step explanation:
Since the above sequence is a geometric sequence
For an nth term in a geometric sequence
[tex]A(n) = a ({r})^{n - 1} [/tex]
where
a is the first term
r is the common ratio
n is the number of terms
From the question
a = - 6
To find the common ratio divide the next term by the previous term
That's
r = 18/-6 = - 3 or -54/18 = - 3
Since we are finding the 12th term
n = 12
Substitute these values into the above formula
We have
[tex]A(12) = - 6 ({ - 3})^{12 - 1} [/tex]
[tex]A(12) = - 6 ({ - 3})^{11} [/tex]
We have the final answer as
A(12) = 1,062,882Hope this helps you

Find the distance that (5, 1) is from the origin. Round to three decimal places.
Answer: Distance = 2.449
Step-by-step explanation:
Given that the distance that (5, 1) is from the origin. That is (0,0) to (5,1)
where
X1 = 0
X2 = 5
Y1 = 0
Y2 = 1
The distance from the origin to the point (5, 1) can be calculated by using the formulae
Substitute all the parameters into the formular
D = [tex]\sqrt{(X2-X1) + (Y2-Y1)}[/tex]
D = [tex]\sqrt{(5-0) + (1-0)}[/tex]
D = [tex]\sqrt{5 + 1}[/tex]
D = [tex]\sqrt{6}[/tex]
D = 2.44948
D = 2.449 ( Three decimal places)

Suppose "35" cars start at a car race. In how many ways can the top 3 cars finish the race?
Answer:
Number of ways top 3 cars finish the race = 39,270
Step-by-step explanation:
Given:
Total number of cars = 35
Number of top cars = 3
Find:
Number of ways top 3 cars finish the race
Computation:
It is a permutation based problem.
So,
npr = n! / (n-r)!
35p3 = 35! / (35! - 3!)
35p3 = 35 ! / 32!
35p3 = 35 × 34 × 33
35p3 = 39,270
Number of ways top 3 cars finish the race = 39,270
Assume a healthy heart beats exactly 70 times per minute. If an individual lives to age 85 years, estimate the number of heartbeats in his or her lifetime, using scientific notation.
Answer:
3.12732 × 10⁹ beats
Step-by-step explanation:
Given that, in 1 min, the heart of an individual makes 70 beats, the number of beats the heart of the healthy individual makes in 85 years can be calculated as follows:
1 yr = 365 days, therefore,
85yrs = 85*365 = 31,025 days
1 day = 24 hours
31,025 days = 31,025*24 = 744,600 hours.
1 hr = 60 mins
744,600 hours = 744,600*60 = 44,676,000 mins
This means the individual lived for 44,676,000 mins (85yrs)
If 70 beats are made in 1 min, therefore, in 85yrs, the individual will make:
44,676,000*70 = 3,127,320,000 beats = 3.12732 × 10⁹ beats in 85yrs
Sean took the bus from Seattle to Boise, a distance of 506 miles. If the trip took
7 2/3 hours, what was the speed of the bus?
Answer:
66 miles per hour
Step-by-step explanation:
To find the speed, divide the distance by the amount of time:
506 ÷ 7 2/3
= 66
= 66 miles per hour
Answer:
66
Step-by-step explanation:
Notice that the problem is asking us to find the rate for Sean's trip. Since we are also given the distance he is traveling and the travel time, we should use the distance, rate, and time formula.
d=rt
where d=distance r=rate t=time
We are given
d=506 mi
r=?
t=723=233 hr
Solving for rate and then substituting the given information into the distance, rate, time formula gives
r=dt=506233=5061⋅323=66
So Sean drove at a rate of 66 mph.
