Answer:
Measure of the side, x = 5.25 units
Step-by-step explanation:
Figure B is a scale image of figure A.
That means figure B is an image and figure A is a pre-image.
Scale factor for the dilation from figure A to figure B = 1.75
Scale factor = [tex]\frac{\text{Side of image B}}{\text{Side of pre-image A}}[/tex]
1.75 = [tex]\frac{x}{3}[/tex]
x = 1.75 × 3
x = 5.25 units
Therefore, measure of the side figure B is 5.25 units.

13. Find the measure of ZABC. Show your work.
Answers
Answer:
47°
Step-by-step explanation:
In the picture attached, the problem is shown.
When two secants intersect at a point, the angle made is one-half of the difference between the greater arc and the minor arc formed. In this case:
∠ABC = 1/2*(arc DE - arc AC)
Replacing with data from the picture:
∠ABC = 1/2*(142° - 48°)
∠ABC = 47°

You have found the following ages (in years) of all 4 zebras at your local zoo: 14, 15, 9, 1 What is the average age of the zebras at your zoo? What is the variance?
Answers
Answer:
9.8. is the Average Age
30.7 is the Variance
Step-by-step explanation:
9.8 is the Average Age and the 30.7 is the Variance.
What is Variance?The term variance refers to a statistical measurement of the spread between numbers in a data set.
Given that, 4 zebras at a local zoo have ages 14, 15, 9, 1,
We need to find the average age and the variance,
we know that,
Average = Sum of all the values of the set given / Number of values in the set
And,
Variance = sum of all the values of (x - means) ² / (n)
So,
Average age = 14 + 15 + 9 + 1 / 4 = 39/4 = 9.75
Variance =
(14-9.75) ² = 18.06
(15-9.75) ² = 27.56
(9-9.75) ² = 0.5625
(1-9.75) ² = 76.56
= 18.06 + 27.56 + 0.5625 + 76.56 / 4
= 30.68 ≈ 30.7
Hence, 9.8 is the Average Age and the 30.7 is the Variance.

7. The largest of the Great Pyramids in Egypt was built with a square base,
having edges that measured 754 feet and a height of 481 feet. Today, after
years of erosion, the base edges are 745 feet and its height is 471 feet. To the
nearest cubic foot, find the difference between the original and current
volumes of the pyramids.
Please show work
Answers
Answer:
Difference between the original and current volumes = 4013140.30 cubic feet
Step-by-step explanation:
Largest pyramid has the square base with one edge = 754 feet
Area of the square base = (Side)²
= (754)²
= 568516 square feet
Volume of the pyramid = [tex]\frac{1}{3}(\text{Area of the base})(\text{Height})[/tex]
= [tex]\frac{1}{3}\times 568516\times 481[/tex]
= 91152065.3 cubic feet
After erosion,
Area of the base = (745)² = 555025 square feet
Volume of the pyramid = [tex]\frac{1}{3}(555025)(471)[/tex]
= 87138925 cubic feet
Difference between the original and current volumes of the pyramid
= 91152065.30 - 87138925
= 4013140.30 cubic feet

Answers

[tex]3-x-1[/tex]
[tex]-x+2[/tex]
3-1(x+1) = 3-x-1
Step 1. distribute the negative sign
2(-x-1) = 3-x-1
Step 2. distribute the 3
-2x-3= 3-x-1
add 3 on both sides
-2x = 6 - x - 1

For f(x)-3x+1 and g (x)-x^2-6 find (f•g)(x)
Answers
Answer & Step-by-step explanation:
For this problem, all we have to do is multiply the two expressions.
f(x) = 3x + 1
g(x) = x² - 6
Now, let's set up our equation for multiplication.
(f * g)(x) = (3x + 1)(x² - 6)
(f * g)(x) = 3x³ - 18x + x² - 6
(f * g)(x) = 3x³ + x² - 18x - 6
So, (f * g)(x) is 3x^3 + x^2 - 18x - 6
the correct Answer is
3x^3+x^2-18x-6

write this trinomial in factored form 4b^2 + 17b + 15
Answers
Answer:
(b + 3)(4b + 5)
Step-by-step explanation:
Given
4b² + 17b + 15
Consider the factors of the product of the b² term and the constant term which sum to give the coefficient of the b- term.
product = 4 × 15 = 60 and sum = 17
The factors are 12 and 5
Use these factors to split the b- term
4b² + 12b + 5b + 15 ( factor the first/second and third/fourth terms )
= 4b(b + 3) + 5(b + 3) ← factor out (b + 3) from each term
= (b + 3)(4b + 5) ← in factored form

What is a sample space?A sample space can be defined as a set of all possible outcomes of a random experiment.
The sample space is represented by the symbol, ‘S’. Sample space can also be expressed using the set notation, {}.
Given that, a bag has 4 balls: 1 red (R), 1 green (G), 1 yellow (Y), and 1 blue (B), we need to find the sample space for this data,
So,
Since, the sample space is the all the data in the set,
Therefore, the whole set is = 1 red (R), 1 green (G), 1 yellow (Y), and 1 blue (B).
Therefore,
S = {R, G, Y, B}
Hence, the sample space for the given information is A. {R, G, Y, B}.
