Find the measure of angle x 125
Answer:
x = 125 degrees
Step-by-step explanation:
The vertical angles theorem states that two angles opposite to each other that are formed from 2 intersecting lines are congruent.
Therefore, angle x and the angle that is 125 degrees are congruent to each other.
So, x=125 degrees.

A line passes through the point (-10,-4) has a slope of -1/2
Note: Consider we need to find the equation of the line because the question statement is missing.
Given:
A line passes through the point (-10,-4) has a slope of [tex]-\dfrac{1}{2}[/tex].
To find:
The the equation of the line.
Solution:
The point slope form of a line is:
[tex]y-y_1=m(x-x_1)[/tex]
Where, m is the slope of the line and [tex](x_1,y_1)[/tex] is the point on the line.
A line passes through the point (-10,-4) has a slope of [tex]-\dfrac{1}{2}[/tex]. So, the equation of the line is:
[tex]y-(-4)=-\dfrac{1}{2}(x-(-10))[/tex]
[tex]y+4=-\dfrac{1}{2}(x+10)[/tex]
[tex]y+4=-\dfrac{1}{2}x-5[/tex]
Subtract 4 from both sides, we get
[tex]y+4-4=-\dfrac{1}{2}x-5-4[/tex]
[tex]y=-\dfrac{1}{2}x-9[/tex]
Therefore, the equation of the line is [tex]y=-\dfrac{1}{2}x-9[/tex]

A statistician constructed the 95 percent confidence interval (2.3, 3.7) to estimate the slope of a regression model for a set of bivariate data with 24 data values. If the sample size n changes but all other things remain the same, which of the following claims about the confidence interval is true ?
A: The interval becomes narrower if n = 20.
B: The interval width remains the same if n = 20.
C: The interval becomes wider if n = 28.
D: The interval becomes narrower if n = 28.
E: The interval width remains the same if n = 28.
Answer:
D: The interval becomes narrower if n = 28.
Step-by-step explanation:
D: The interval becomes narrower if n = 28.
The claim that is true regarding confidence interval would be:
D). The interval becomes narrower if n = 28.
What is Interval?Interval is described as the range in which the values fluctuate. This involves one initial or beginning value while the other is the end value and in between these two, the values range.
Given that,
Confidence interval = 95%(2.3, 3.7)
No. of data values = 24
In this case, the true statement about the effect of alteration in the size of the sample would be the interval becoming more concise/narrow in case n become 28 from 24.
Thus, option D is the correct answer.

Exercise 8.12 introduces data on the average monthly temperature during the month babies rst try to crawl (about 6 months after birth) and the average rst crawling age for babies born in a given month. A scatterplot of these two variables reveals a potential outlying month when the average temperature is about 53F and average crawling age is about 28.5 weeks. Does this point have high leverage
Answer:
The point has a high leverage
Step-by-step explanation:
The point has a high leverage as it would act as an infinitesimal point that will have a very huge/drastic impact on the fit of the model, and this impact can be seen in such ways as listed below :
Smaller coefficient of determinationHigher sum of squares errorremoving this point will eliminate these drastic impact and make the correlation to be better.
From the information given about the outliner, the given point is not influential and therefore does not have high leverage.
What is an outliner?An outlier refers to a data point whose response does not follow the general trend of the rest of the data.
A data point has high leverage if it has an extreme predictor x value. Here, x = 53 and, y = 28.5.
X is not an extreme point, the data point is not high leverage but an outlier. The data point doesn't follow the general trend of the rest of the data.
Hence the given point is not influential.

The median for City A is less than the median for City B.
Answer:
During the 10 wk period, the rainfall amount recorded most often for City B was 1 in.
Step-by-step explanation:
Given the data :
City A :

What two numbers multiply to 48 and add up to 11?
WILL GIVE BRAINLIEST!!!!!!!!!!!!!!!!!!!
Answer:
The factor pairs of the number 48 are: 1 x 48, 2 x 24, 3 x 16, 4 x 12, and 6 x 8. When you multiply each of these factor pairs together, you get 48 and two numbers that add up to 11 is 10+1 or 6+5
Step-by-step explanation:
The two numbers that represent the situation are 5.5+4.21307i and 5.5−4.21307i.
To find two numbers that multiply by 48 and add up to 11, we can set up a system of equations and solve it. Let's denote the two numbers as x and y.
The first equation represents the multiplication of the two numbers: xy = 48.
The second equation represents the addition of the two numbers: x + y = 11.
To solve this system of equations, we can use various methods such as substitution or elimination. Here, we'll use the substitution method.
From the second equation, we can isolate one variable. Let's solve it for x: x = 11 - y.
Substituting this value of x into the first equation:
(11 - y)y = 48.
Expanding and rearranging the equation:
11y - y² = 48.
Rearranging again to bring all terms to one side:
y² - 11y + 48 = 0.
Now we have a quadratic equation. Factoring or using the quadratic formula, we find that y = 8 or y = 3.
y=5.5+4.21307i
y=5.5−4.21307i

The volume of cracker boxes are normally distributed, with a mean of 7 oz and a standard deviation of 0.2 oz. If a box is selected at random, What is the probability of getting an amount between that is at least 7.5 oz
Answer:
0.0062 = 0.62% probability of getting an amount between that is at least 7.5 oz.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Mean of 7 oz and a standard deviation of 0.2 oz.
This means that [tex]\mu = 7, \sigma = 0.2[/tex]
What is the probability of getting an amount between that is at least 7.5 oz?
This is 1 subtracted by the pvalue of Z when X = 7.5. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{7.5 - 7}{0.2}[/tex]
[tex]Z = 2.5[/tex]
[tex]Z = 2.5[/tex] has a pvalue of 0.9938
1 - 0.9938 = 0.0062
0.0062 = 0.62% probability of getting an amount between that is at least 7.5 oz.

Answer:
HN = 102 units
LJ = 90 units
GJ = 176 units
Step-by-step explanation:
Since, point N inside the triangle is the circumcenter of the given circle,
HN = GN = NJ = Radii of the circle
Therefore, measure of HN = measure of GN = measure of JN = 102 units
By applying Pythagoras theorem in ΔNLJ,
JN² = NL² + LJ²
(102)² = (48)² + (LJ)²
(LJ)² = (102)²- (48)²
LJ = √8100
LJ = 90 units
m(GJ) = 2[m(GK)] [Since NK bisects GJ]
= 2(88)
= 176 units
Answer:
HN = 102 units
LJ = 90 units
GJ = 176 units

Alternate exterior angles are congruent.
Which angle forms a pair of alternate
exterior angles with angle 1?
Answer:
<8
Step-by-step explanation:
The alternate exterior angle property implies that the two angles must be an alternate exterior angles. Thus form the given diagram,
<3 = <6 (alternate interior angles)
<4 = <5 (alternate interior angles)
Therefore,
<1 = <8 (alternate exterior angles)
<2 = <7 (alternate exterior angles)
Thus, the angle that forms a pair of alternate exterior angle with angle 1 is angle 8.
