Please help what does A equal
Answer:
26°
Step-by-step explanation:
∠a and the 154° angle are both supplementary, so their sum is equal to 180°.
[tex]a+154=180[/tex]
[tex]a=26[/tex]
So, m∠a=26°.

Refer to the accompanying data table, which shows the amounts of nicotine (mg per cigarette) in king-size cigarettes, 100-mm menthol cigarettes, and 100-mm nonmenthol cigarettes. The king-size cigarettes are nonfiltered, while the 100-mm menthol cigarettes and the 100-mm nonmenthol cigarettes are filtered. Use a 0.05 significance level to test the claim that the three categories of cigarettes yield the same mean amount of nicotine. Given that only the king-size cigarettes are not filtered, do the filters appear to make a difference?
Answer:
So i'm going to assume that the rest of the question is the same as my homework.
It says to determine the null and alternative hypothesis
H0 is mean1=mean2=mean3
H1 is at least one of the three population mean is different from the others
It says find the F test stat
You need some form of a TI-84 plus calculator. From there, you take the data from the King-Size nicotine (mg) in List 1. 100mm-Menthol in List 2. 100-mm nonmenthol in List 3. From there you go to STAT then hit TEST then scroll all the way to the bottom where it says AVOVA. Click enter, from there you see ANOVA(, from there you have to tell it where the lists are. after ANOVA(, put L1, L2,L3 (assuming that's where you put your data into) so when all said and done in your calculator, it should look something like this: ANOVA(L1, L2, L3) then hit enter. The first line where it says F=, that's your test stat.
Find the P value:
You find the P value in the same menu as your test stat. It should be the number right below your test stat. P=
What is the conclusion for this hypothesis ?
Since our P value is less then alpha, we reject the null hypothesis (H0). From there we can conclude that there IS SUFFICIENT evidence to warrant rejection of the claim that the three categories of cigarettes yield the same mean amount of nicotine
Do the filters appear to make a difference?
Given that the king-size cigarettes have the largest mean, it appears that the filters do make a difference
Step-by-step explanation:
The king-size cigarettes have the largest mean, it appears that the filters do make a difference.
How to form the hypotheses?There are two hypotheses. First one is called null hypothesis and it is chosen such that it predicts nullity or no change in a thing. It is usually the hypothesis against which we do the test.
The hypothesis which we put against null hypothesis is alternate hypothesis.
Null hypothesis is the one which researchers try to disprove.
H1 is at least one of the three population mean is different from the others.
To find the P value in the same menu as your test stat. It should be the number right below your test stat.
The conclusion for this hypothesis, Since our P value is less then alpha, we reject the null hypothesis (H0).
From there we can conclude that there is a sufficient evidence to warrant rejection of the claim that the three categories of cigarettes yield the same mean amount of nicotine.
The king-size cigarettes have the largest mean, it appears that the filters do make a difference.

V

Answer: 70, 130
Step-by-step explanation:
In the given normal distribution with a mean of 100 and standard distribution of 15, 95% of values will fall between 70 and 130 using the Empirical rule of 95%.
Step-by-step explanation:
A normal distribution with a mean of 100 and a standard distribution of 15 is given.
We will find where 95% of data fall in the given normal distribution.
What is the Empirical rule of 95%?It states that in a normal distribution approximately 95% of observations fall within two standard deviations from the mean on both sides of the normal curve.
The mean in a normal distribution is the center of the normal curve.
The standard deviation in a normal distribution is the distance from the mean to the required point on either side.
We have,
Mean = 100
Standard deviation = 15
Applying the 95% rule we get,
On the right side of the normal curve
Mean + 2 x standard deviation = 100 + 2x 15 = 100 + 30 = 130.
On the left side of the normal curve,
Mean - 2 x standard deviation = 100 - 2x15 = 100 - 30 = 70.
Thus, we see that by using the Empirical rule of 95%, 95% values will fall between 70 and 130.

What is the value of x in the figure?
(4x + 2)
150°
Answer:
x=37
Step-by-step explanation:
By Vertical Angles Theorem (VAT), (4x+2) is equal to 150º, so then you just subtract 2 from both sides of the equation 4x+2 = 150, to make it 4x = 148, and then divide both sides by 4 to isolate x, and then you get x=37.

On discovering that her family had a 70% risk of heart attack, Erin took treadmill test to check her own potential of having a heart attack. The
doctors told her that the reliability of the stress test is 67%. What is the probability that Erin will not have a heart attack and the test predicts that
she will?

© B. 0.201
© C. 0.231
0.469
Answer:
A. 0.099
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened.
[tex]P(A \cap B)[/tex] is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: She does not have a heart attack.
Event B: tests predicts that she will have a heart attack
The doctors told her that the reliability of the stress test is 67%.
This means that there is a 100 - 67 = 33% of not having a heart attack if the test predicts she will have a heart attack, so:
[tex]P(B|A) = 0.33[/tex]
70% risk of heart attack
So 100 - 70 = 30% probability of not having a heart attack, which means that [tex]P(A) = 0.3[/tex]
What is the probability that Erin will not have a heart attack and the test predicts that she will?
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
[tex]P(A \cap B) = P(B|A)*P(A) = 0.33*0.3 = 0.099[/tex]
The correct answer is given by option A.

The figure shown is created by joining three rectangles. Enter the area of the figure, in square centimeters. Round to the nearest hundredth.
Answer:
235
Step-by-step explanation:
first, separate the floor into 3 different rectangles to calculate the area and then add them together.
area of rec=L*B
rec 1: 9*12.5=112.5
rec 2: (13.5-5.5)*(19.5-9-7)=28
rec 3:7*13.5=94.5
Then:
112.5+28+94.5=235
Which function has a constant rate of change equal to -3?
The given function with a constant rate of change that equals -3 is: 2y = -6x + 10.
What is Constant Rate of Change?The constant rate of change of a function = change in y / change in x. Given an equation of a function in slope-intercept form, y = mx + b, the constant rate of change is represented as m.
1. Constant rate of change of the function on the table using two pairs of values, (0, 2) and (1, 5) is:
(5 - 2)/(1 - 0) = 3/1
Constant rate of change = 3.
2. Constant rate of change of the function of the set of ordered pairs using two pairs of values, (4, 4) and (2, 2) is:
(4 - 2)/(4 - 2) = 2/2
Constant rate of change = 1.
3. Constant rate of change of the graphed function using two points on the line, (1, 1) and (0, 3) is:
(3 - 1)/(0 - 1) = 2/-1
Constant rate of change = -2.
4. Constant rate of change of the function 2y = -6x + 10:
Rewrite the equation in slope-intercept form
2y/2 = -6x/2 + 10/2
y = -3x + 5
Constant rate of change = -3.
Therefore, the function with a constant rate of change is: 4. 2y = -6x + 10
