How can you decide which operation to use to solve a problem?
Answers
Answer:
it you're asking for like an equation like "4x +3 = 15 " then you do the opposite of what the equation is doing. Basically undoing the problem to get back to the roots of it. like for the example i provided you would subtract 3 from both sides, because it was added originally. then you would divide both sides by 4 because originally you were multiplying.

100p=1887p move variable to the left change sign
100p-1887p collect like terms

For a study of adolescents' disclosure of their dating and romantic relationships, a sample of 224 high school students was surveyed. One of the variables of interest was the level of disclosure to an adolescent's mother (measured on a 5-point scale, where 1 = "never tell" and 5 ="always tell"). The sampled high school students had a mean disclosure score of 3.38 and a standard deviation of 0.98. The researchers hypothesize that the true mean disclosure score of all adolescents will exceed 3. Do you believe the researchers?
Conduct a formal test of hypothesis using α = 0.05. Set
Answers
Answer:
The decision rule is
Reject the null hypothesis
The conclusion is
There sufficient evidence that the true mean disclosure score of all adolescents will exceed 3
Step-by-step explanation:
From the question we are told that
The sample is n = 224
The sample mean is [tex]\= x = 3.38[/tex]
The standard deviation is [tex]s = 0.98[/tex]
The population mean is [tex]\mu = 3[/tex]
The level of significance is [tex]\alpha = 0.05[/tex]
The null hypothesis is [tex]H_o : \mu = 3[/tex]
The alternative hypothesis is [tex]H_a : \mu > 3[/tex]
Generally the test statistics is mathematically represented as
[tex]z = \frac{ \= x - \mu }{ \frac{s}{ \sqrt{n} } }[/tex]
=> [tex]z = \frac{ 3.38 - 3 }{ \frac{0.98 }{ \sqrt{224} } }[/tex]
=> [tex]z = 5.80[/tex]
From the z table the area under the normal curve to the right corresponding to 5.80 is
[tex]p-value = 0[/tex]
From the value obtained we that [tex]p-value < \alpha[/tex] , hence
The decision rule is
Reject the null hypothesis
The conclusion is
There sufficient evidence that the true mean disclosure score of all adolescents will exceed 3
What statistical procedure would a college admissions office use if they wanted to know if doing physical exercises can help the same group of students improve their GPA
Answers
Answer: ANOVA
Step-by-step explanation:
The statistical procedure that a college admissions office would use if they wanted to know if doing physical exercises can help the same group of students improve their GPA is the ANOVA.
Analysis of variance is used to know whether the means there's a significant difference between two or more groups. Different sample means will be compared in order to checks the effect of the factors involved. Based on the question above, the null hypothesis will be that physical activity doesn't have a significant relationship with the GPA of the college students.

Let the parts be 2x, 3x and 5x.
Sum= 25000
Therefore,2x+3x+5x=25000
10x=25000
x=25000/10
x=2500
Therefore, parts:-
1. 2×2500=5000
2. 3×2500=7500
3. 5×2500=12500
Answer:
5000, 7500, 12500
Step-by-step explanation:
[tex]2 + 3 + 5 = 10[/tex]
[tex]25000[/tex] ÷ [tex]10[/tex] = [tex]2500[/tex]
[tex]2500[/tex] × [tex]2 = 5000[/tex]
[tex]2500[/tex] × [tex]3 = 7500[/tex]
[tex]2500[/tex] × [tex]5 = 12500[/tex]
[tex]\therefore[/tex] [tex]25000[/tex] will split into [tex]5000[/tex], [tex]7500[/tex], and [tex]12500[/tex].
To check if the answer is correct, you can add the values up and see if they sum up to [tex]25000[/tex]:
[tex]5000 + 7500 + 12500 = 25000[/tex]

On a coordinate grid, point P is at (1, 7) and point R is at (−2, −3). Points Q and S are a reflection of both points across the x-axis. What are the coordinates of Q and S? (1 point) Q(−1, 7), S(2, −3) Q(−1, −7), S(2, 3) Q(−1, 7), S(−2, 3) Q(1, −7), S(−2, 3)
Answers
9514 1404 393
Answer:
(d) Q(1, −7), S(−2, 3)
Step-by-step explanation:
Reflection across the x-axis negates the y-coordinate:
(x, y) ⇒ (x, -y) . . . . reflection across the x-axis
Then we have ...
P(1, 7) ⇒ Q(1, -7)
R(-2, -3) ⇒ S(-2, 3)
These coordinates match the last choice.

a, independent. b. exhaustive. C.mutually exclusive. d. continuous.
Answers
Answer:
Mutually exclusive
Step-by-step explanation:
Mutually exclusive events exist if only one of the events can occur on any one trial.
Events are considered to be mutually exclusive if only one of them can occur on any given trial.
So, option c. mutually exclusive is correct.
Define event.An event is a defined collection of outcomes of a random experiment in probability theory. Because the sample space is the collection of all possible outcomes to a random experiment, another definition of event is any subset of a sample space.
If two events cannot occur at the same moment, they are mutually exclusive or discontinuous.
Events are considered to be mutually exclusive if only one of them can occur on any given trial. So, option c. mutually exclusive is correct.

A polynomial function has x-intercepts at -2, 1/2, and 2 and a relative maximum at x = -1.
Which graph matches the description of this function?
Answers
Answer: A :)
Step-by-step explanation:
The function goes through -2, 1/2, and 2, maximum goes through x= -1
By using the information about the x-intercepts and the relative maximum, we can see that the correct option is A.
How to find the correct graph of the polynomial?
First, we know that we have a relative maximum at x = -1, this means that we have a "mountain" at x = -1.
The only two graphs with that feature are A and B.
Now we also know that the x-intercepts are:
-2, 1/2, and 2.
Where the x-intercepts are the values of x at which the graph intercepts the x-axis. There you can see that we have one negative and two positives, from that, we can conclude that the only correct option can be A (because B has two negatives and one positive x-intercepts).
Finally, we conclude that the correct option is A.

Answers
Answer:16
Step-by-step explanation:
The measure of the angle m<G is 118 degrees
The sum of an interior angle of a triangle is 180 degrees
Given the following angles of a triangle:
m∠G=(8x+14)
m∠H=(3x-6)
m∠I=(x+16)
Since the sum of angle is 180 degrees, hence;
m∠G + m∠H + m∠I = 180
8x + 14 + 3x - 6 + x + 16 = 180
12x + 24 = 180
12x = 180 - 24
12x = 156
x = 156/12
x = 13
Get the measure of angle m<G
m<G = 8x + 14
m<G = 8(13) + 14
m<G = 104 + 14
m<G = 118 degrees
Hence the measure of the angle m<G is 118 degrees

Step-by-step explanation:
Let n represent the number of nickels Bob has. Then 18-n is the number of dimes, and the total value (in cents) is ...
5n +10(18-n) = 115
-5n +180 = 115 . . . simplify
65 = 5n . . . . . add 5n-115
13 = n . . . . . . . divide by 5
Bob has 13 nickels.
