Hi :)
The reciprocal of 5 is 1/5.
Every number has a reciprocal except 0.
For example
5/1 is just 5 but the reciprocal of that would be 1/5.
Essentially flipping the fraction.
Answer: [tex]\frac{1}{5}[/tex]
Step-by-step explanation:
Reciprocal means the multiplicative inverse of a number. It means the numerator and the denominator which their places.
Since 5 does not have a denominator, we can keep the denominator as 1. The fraction will be [tex]\frac{5}{1}[/tex]. Now when we switch the numerator and denominator, we will get [tex]\frac{1}{5}[/tex].
A rare disease exists with which only 2 in 1000 isaffected. There is a test for the disease that a correct positive result (patientactually has the disease) occurs95%of the time while a false positive result(patient does not have the disease) occurs1%of the time.a) What is the prior distribution of the disease and the posterior distributionof the disease given the positive result?b) Is the test good? Explain that counter-intuitive result.
Answer:
the test is good since it is right 98 percent of the time an if the test is wrong you can just take it again

When the sum of the internal angles of a polygon is 10 right angles, then how many sides does it have?
Answer:
7
Step-by-step explanation:
Let's say our sum is s.
s = 10 right angles
a right angle is 90 degrees
s = 10 (90)
s= 900
Given the amount of sides in a polygon (n), the sum of the interior angles is equal to
(n-2) * 180
Therefore, the sum of the interior angles is equal to
(n-2) * 180 = 900
divide both sides by 180 to help isolate n
n-2 = 5
add 2 to both sides to isolate n
n = 7
The area of a rectangle is 77 yd square, and the length of the rectangle is 3 yd more than twice the width. Find the dimensions of the rectangle.
Length :
Width :
Answer:
Length = 14 yd
Width = 5.5 yd
Step-by-step explanation:
Let width = x and length = 2x + 3
The formula for area is length x width.
(2x + 3) ( x ) = 77
2x² + 3x - 77 = 0
-77 x 2 = -154
What two numbers multiply to -154 and add to 3?
2x² + 14x - 11x - 77 = 0
2x (x + 7) - 11 (x + 7) = 0
(2x - 11) (x + 7) = 0
x = -7 (this isn't possible so ignore it)
x = 5.5 (width)
Now insert 5.5 into the initial equation.
2 (5.5) + 3 =
11 + 3 = 14
Answer:
Length is 3
width is 25•66

Find (f o g)(x)
Consider f(x) = x + 7 and g(x) = x2 –1
Work Shown:
(f o g)(x) = f(g(x))
f(x) = x + 7
f( g(x) ) = g(x) + 7 ... replace every x with g(x)
f( g(x) ) = x^2-1 + 7 .... plug in g(x) = x^2-1
f( g(x) ) = x^2 + 6
(f o g)(x) = x^2 + 6

Answer:
-3x + 6
Step-by-step explanation:
-3(x - 2) to find the equivalent of this expression, we need to multiply inside the parenthesis with -3 (with both x and -2)
-3(x - 2 = -3x + 6 (two negative expressions multiplied results in positive)
Chris owes $17,000 to a bank. The debt grows with 8% annual interest that compounds every year. How
much will Chris owe in one year?
A. 18,014
B. 18,242
C. 18,360
D. 18,557
Answer:
18360
Step-by-step explanation:
A = P (1 + r/n)^(nt) where A is the amount in the account, P is the principle, r is the interest rate , n is the times compounded per year, t is the number of years
A = 17000 (1 + .08/1)^(1*1)
A = 17000( 1.08)^1
A = 18360

The point that will be in the function p⁻¹(x) is (1,-3), the correct option is C.
What is a Function?A function is a law that relates a dependent and an independent variable.
The function p(x) has point (-3, 1 )
An inverse of the function is obtained by interchanging the value of y and x, then solving the equation for y in terms of x

Janice is building a model volcano for the science fair. To find the right ratio, she starts by mixing small amounts of baking soda and vinegar. She finds that adding 1.5 teaspoons of baking soda for every fluid ounce of vinegar produces the best eruption. If Janice plans to us 0.5 cups of vinegar for her project, how many tablespoons of baking soda should she use?
Answer:
6 tablespoons of baking soda
Step-by-step explanation:
There are 8 fluid ounces in 1 cup and shes going to use half a cup so that means shes going to use 4 fluid ounces of vinegar. To find how much baking soda she is going to use, we are going to multiply.
1.5 * 4 = 6
Best of Luck!
Answer:
3 Tablespoons, 6 teaspoons
Step-by-step explanation:
In order to find the right ratio of Baking Soda to Vinegar we have to find ratio given,... they tell us that for every 1.5 teaspoon of baking soda, you must add 1 fluid ounce or vinegar,... thus the ratio of Baking Soda to Vinegar is (1.5 teaspoon / 1 Fluid ounce)
There are:
3 teaspoons = 1 Tablespoons
8 fluid ounces = 1 cup
So if you use 0.5 cups of Vinegar as they tell us we do than that is the same thing as using 4 Fluid ounce, and because your problem say 1.5 teaspoon of baking soda for every Fluid ounce of vinegar all you have to do it multiply your 1.5t by your 4 to get how many teaspoons of Baking Soda you will need,...
1.5 * 4 = 6
You need 6 teaspoons or 3 Tablespoons,...
Hope that helps,... and I'll see you in life,... well not, literally, but you get what I mean,... Chow!
mr tan is 42 years old and mrs tan is 44 years old now. they have 3 children who are 7 years, 5 years and 2 years old now. in how many year time will the sum of mr and mrs tan's age be 4 times of the sum of their 3 children's age
Answer:
3 years
Step-by-step explanation:
let the number of years required be x
hence
42+x+44+x = 4(7+x+5+x+2+x)
86+2x = 4(14+3x)
86+2x = 56+12x
2x-12x = 56-86
-10x = -30
x = 3

Find the solution for
h - 12 =6
Answer:
H-12=6
H−12+12=6+12
h=18
Answer:
h=18
Step-by-step explanation:
h-12=6
is the normal eqaution, you need to determine the value of h, on the left side of the eqaution you have negative twelve we must get the h on its own by moving the 12 to the right side using of basic math rules you must know that when you have a negative and want to move it to the right hand side it must become a positive
so in formula it wil look like this
h = 6 + 12
Add up 6 with 12 that wil give you 18
so the value of h is then 18
h = 18

Tamara rode her bicycle 8 miles in 0.5
hours. What was the average rate that
she rode her bicycle in miles per hour?
pls give me the step by step
Answer:
16 miles per hour (mph)
Step-by-step explanation:
Okay, so the beginning of the question states that Tamara rode her bicycle 8 miles in 0.5 hours.
0.5 is equivalent to 1/2 (one-half).
This means that she rode 8 miles in just half of an hour (30 minutes).
If she continues at this rate, she will have rode another 8 miles in the next 30 minutes.
And, 8 + 8 = 16.
Therefore, the average rate that she rode her bicycle is 16 miles per hour (mph).

BRAINLEST IF CORRECT!!!!
Answer: x = 5
Step-by-step explanation:
Given information
The combined angle is a right angle meaning it is 90°
Angle 1 = 8x°
Angle 2 = 50°
Set equation
Angle 1 + Angle 2 = Total angle
Substitute values into the equation
8x + 50 = 90
Subtract 50 on both sides
8x + 50 - 50 = 90 - 50
8x = 40
Divide 8 on both sides
8x / 8 = 40 / 8
x = 5
