How can you decide which operation to use to solve a problem?

Answers

Answer 1

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.

, and \text{m}\angle I = (x+16)^{\circ}m∠I=(x+16)

. Find \text{m}\angle G.m∠G.

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

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

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.

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

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.

b. domain: {-6, 0, 6), range: {-3, 0, 3}
c. domain: {3, 0, 3), range: {6, 0, 6}
d. domain: {6,0, 6), range: {3, 0,3}​

Answers

Answer:

The domain: {-3, 0, 3}

The range: {-6, 0, 6}

Therefore, option (a) is correct.

Step-by-step explanation:

Given the table

x    -3      0      3

y     -6     0      6

Determining the Domain:

We know that the domain of a relation is the set of all the x-values of the set X. In other words, the domain of relation consists of all the input values.

Therefore, the domain: {-3, 0, 3}

Determining the Range:

We know that the range of a relation is the set of all the y-values of the set Y. In other words, the range of relation includes all the output values.

Therefore, the range: {-6, 0, 6}

Therefore, we conclude that option (a) is correct.

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]:
