Answer:
21
Step-by-step explanation:
The cube root of 9.261 is 2.1 because 2.1 × 2.1 × 2.1 = 9.261.
in scientific notation, we leave only 1 digit to left of the decimal point.
now
35681000000 is really the same as 35681000000.0
so we can say the zero is way over there on the right-side, and we have to move it to the left, right in front of the "3", between "3" and "5", so the "3" is the only digit to the left of the decimal point.
to do that, we'll be moving it hmmmmm 10 slots over, therefore
35681000000
3.5681000000 x 10¹⁰
or
3.5681 x 10¹⁰ <---- using only significant digits.
Question 1:To change the new image back into the original image, just do the opposite.
To change the original image to the new image, we added x by 3 and subtracted 7 from y.
To change the new image back to the original image, subtract x by 3 and add 7 to y.
Writing this into an equation gives us the following:
Question 2:An isometry is a transformation of an image where the new image is congruent to the preimage.
The second and third choices are incorrect because the preimage is not congruent to the new image in these two choices.
The fourth choice is incorrect because having the same position is not an isometric transformation.
Thus, the answer is the first choice.
Answer:
Step-by-step explanation:
Given equation:
Multiply both sides by (x - 1):
Expand the brackets:
Add r to both sides:
Divide both sides by r:
Answer:
the probability that a randomly chosen test-taker will score 142 or lower = 0.8643
Step-by-step explanation:
We are given;
Data point; x = 142
Mean; μ = 153
Standard deviation; σ = 10
So,let's find the z-score using;
z = (x - μ)/σ
z = (142 - 153)/10
z = -1.1
From the z-distribution table attached, the probability is;
P(z < -1.1) = 1 - 0.13567 ≈ 0.8643
