–9.96 + 9.9t = 1.54 + 7.7t + 7.2t
Answer: -2.3
Step-by-step explanation:
–9.96 + 9.9t = 1.54 + 7.7t + 7.2t
–9.96 + 9.9t = 1.54 + 14.9t
-9.96 - 5t = 1.54
-5t = 11.5
t = -2.3
A fruit bowl contains apples, oranges, and bananas. The radius of one of the oranges is 1.45 inches. What is the approximate volume of the orange? Use 3.14 for .
Answer:
12.76 in³
Step-by-step explanation:
The volume of a sphere formula is V = (4/3)πr³.
Here we use 3.14 for π and 1.45 in for r. We get:
V = (4/3)(3.14)(1.45 in)³ ≈ 12.76 in³
The word and in probability implies that we use the ________ rule.
Answer:
Addition Rule
The word or in probability implies that we use the Addition Rule.
The word "and" in probability implies that we use the "Multiplication Rule".
The Multiplication Rule is used when calculating the probability of two or more independent events occurring simultaneously.
It states that the probability of two or more independent events occurring together is equal to the product of their individual probabilities.
In other words, if event A and event B are independent, then the probability of both events A and B happening is given by:
P(A and B) = P(A) x P(B)

Triangle FGH is dilated by a scale factor of 5 to form triangle F'G'H'. Side F'G'
measures 15. What is the measure of side FG?
Answer:
The measure of side FG is 3.
Step-by-step explanation:
Dilation is a process in which the dimensions of a given shape or figure is either increased or decreased by a scale factor to produce its image.
From the given question,
scale factor = 5
measure of side F'G' = 15
Thus,
scale factor = [tex]\frac{measure of side F'G'}{measure of side FG}[/tex]
side F'G' = scale factor x side FG
⇒ 15 = 5 x side FG
So that,
side FG = [tex]\frac{15}{5}[/tex]
= 3
The measure of side FG is 3.

Thompson and Thompson is a steel bolts manufacturing company. Their current steel bolts have a mean diameter of 125 millimeters, and a standard deviation of 7
millimeters.
If a random sample of 44 steel bolts is selected, what is the probability that the sample mean would be greater than 127.1 millimeters? Round your
answer to four
decimal places
Answer:
P(X > 127.1) = 0.0233
Step-by-step explanation:
We are given;
Population mean; μ = 125 mm
Sample mean; x¯ = 127.1 mm
Sample size; n = 44
Standard deviation; σ = 7 mm
Formula for test statistic is;
z = (x¯ - μ)/(σ/√n)
z = (127.1 - 125)/(7/√44)
z = 2.1/1.0553
z = 1.99
From z-table attached;
P(X > 127.1) = P(z > 1.99) = 1 - 0.97670 = 0.0233

A mirror is the shape of an ellipse defined by y^2/7.29 + x^2/6.25 = 1 with units in feet. Which statement identifies the

Answer:

Step-by-step explanation:
a on edg 2021 ^u^
Answer: A. The mirror has a vertical orientation and is 5.4 ft tall.
Step-by-step explanation:
Since the y^2 value is being added first, and the value in its denominator is greater, we know that the ellipse has a vertical major axis.
Therefore, its orientation is vertical.
The square root of is 7.29, so 2.7 is the distance from the center to one of the ellipse's vertices. (You can research further into the equation for ellipses with vertical major axes to learn why that is.)
Multiply 2.7 * 2 = 5.4 to determine the full height of the mirror.
Yay! We figured out that "the mirror has a vertical orientation and is 5.4 ft tall".
