Line segments AB and BC are tangents to Circle P. What is the value of x?
a.117
b.73
c.107
d.146
Answer:
c. 107°
Step-by-step explanation:
In the figure attached, Circle P, segments AB and BC, and angle x are shown.
From circumscribed angle theorem, we know that angle ABC and angle x are supplementary, then:
x + 73° = 180°
x = 180° - 73°
x = 107°
Aisha is playing a game in which she can gain or lose points on each turn. The table below
shows the points she scores on each of four turns in the game.
Aisha states that her highest score is on Turn 3, because 16 is greater than 3, 10, or 9. Use the
drop-down menus to explain Aisha's mistake.
Answer:
A score of -16 represents the lowest of points for these four turns.
The number for Aisha's highest score will be turn 2 on the number line.
That number is 10.
Step-by-step explanation:
Since the options of the drop down menu are not included, you should choose any option similar to lowest.
Aisha's highest score was obtained in turn 2 and that is 10.
Aisha is comparing absolute terms, that is why she believes that -16 represents a good score, while in reality is the worst she got.

Answer: Snail ≈ 96,551.7 hours, North American X-15 ≈ 0.6 hours
Step-by-step explanation:
All you have to do is divide how many miles they go an hour by the total number of miles, which is 2,800.
Part 1: Garden Snail
= [tex]\frac{2,800}{0.029}[/tex]
≈ 96,551.7
Part 2: North American X-15
= [tex]\frac{2,800}{4,520}[/tex]

Answer:
1 5/9
Step-by-step explanation:
9 1/3 can be rewritten as 28/3. The question is asking for you to divide 28/3 by 6. 6 is 6/1, so the expression is 28/3 divided by 6/1. You then do the reciprocal of 6/1 and the expression is [tex]\frac{28}{3} * \frac{1}{6}[/tex]. This gets you 28/18, which is simplified to 14/9 or 1 5/9. Hope this helps!

The scatterplot that represents the monthly values of stock ABC can be
approximated by a line with a positive slope. What type of correlation does
this represent?
O
A. Negative correlation
O
B. No correlation
O
c. Positive correlation
Answer: A. Negative correlation
Step-by-step explanation:
A P E X
The scatterplot that represents the monthly values of stock ABC can be approximated by a line with a positive slope represents positive correlation. The correct option is C.
What is correlation?The relationship between variables is described by correlation. It can be either strong or weak, as well as positive or negative.
Correlations show that there is a relationship between two variables, but one does not always cause the other to change.
A positive correlation indicates that as one variable increases, so does the other.
In this case, the scatterplot of the monthly values of stock ABC can be approximated by a line with a positive slope, indicating that as the stock's value increases over time, so does the corresponding month. As a result, it is a positive correlation.
Thus, the correct option is C.

PLS HELP!!!!!! In a survey of 4530 U.S. adults, 87% said that they would like to donate more to charity. What is the margin of error for the survey? Round to the nearest tenth of a percent
Answer:
Margin of Error = 1.0% to the nearest tenth of a percent.
Step-by-step explanation:
Margin of Error is the width of the confidence interval about the mean.
It is given mathematically as,
Margin of Error = (Critical value) × (standard Error)
Critical value is obtained from the z-tables at the popular confidence level of 95% and z-tables is used because the sample size, 4530, is large enough to approximate the population properties.
Critical value = 1.960
Standard error = σₓ = √[p(1-p)/n]
p = 87% = 0.87
n = sample size = 4530
σₓ = √[0.87×0.13)/4530]
= 0.0049966876
Margin of Error = 1.96 × 0.0049966876 = 0.0097935078 = 0.00979 = 0.979% = 1.0% to the nearest tenth of a percent.

Figure A is translated 3 units right and 2 units up. The translated figure is labeled figure B. Figure B is reflected over the x-axis. The reflected figure is labeled figure C. Which best explains why figure A is congruent to figure C?
On a coordinate plane, triangle A has points (1, negative 2), (3, negative 2), (3, negative 5). Triangle B has points (4, 0), (6, 0), (6, negative 3). Triangle C has points (4, 0), (6, 0), (6, 3). HURRY CHOOSE ONE
A Is congruent to B and B Is congruent to C
A Is congruent to A, B Is congruent to B, C Is congruent to C
Each triangle is a right triangle.
Each triangle is an isosceles triangle.
Answer:
A Is congruent to B and B Is congruent to C
Step-by-step explanation:
Given Figures A, B and C on a coordinate plane with the coordinates below:
Triangle A has points (1, -2), (3, -2), (3, -5).
Triangle B has points (4, 0), (6, 0), (6, -3).
Triangle C has points (4, 0), (6, 0), (6, 3).
The fact that each triangle is a right triangle only shows that the triangles are similar.
For any two shapes to be congruent, they must have in addition to the same shape, the same size.
Therefore, for Triangle A to be congruent to Triangle C, Triangle A must be congruent to Triangle B and Triangle B must be congruent to Triangle C.
Answer:
A = B and B= C
