which of the following shows an equivalent expression to (5 times 3)times 12 if only associative property was used to transform the expression

Answers

There are no choices for this question, but the correct answer would be to re-write the exact same phrase only putting a parentheses around 3×12 instead. The associative property says that you can group your multiplication problem in any order it without changing the value. If we are only applying The associative property then the order it is written in would remain the same. Only the grouping would change.

Associative Property states

A × (B ×C)=(A×B)×C=(A×C)×B

Now, we have to find equivalent expression of

a juice can is shaped like a cylinder ]. it is 12 centimeters wide and 16 centimeters tall. find its volume to the nearest whole number . use 3.14

Answers

To find the volume of the cylinder-shaped juice can, calculate using the formula V = π r² h with the radius being half of the can's width and the given height. The volume is found to be approximately 1804 cm³ when rounded to the nearest whole number.

Calculating the Volume of a Cylinder:

To calculate the volume of a cylinder, you should use the formula V = π r² h. First, we need to determine the radius of the juice can. Since it is given that the can is 12 centimeters wide, that means the diameter is 12 centimeters, and therefore, the radius (r) is half of that, which is 6 centimeters. We also have the height (h) of the can, which is 16 centimeters. Plugging these values into the formula gives us:

V = 3.14 × 6² × 16

Now, we calculate:

V = 3.14 × 36 × 16

V = 3.14 × 576

V = 1803.84 centimeters cubed (cm³)

When we round this to the nearest whole number, the volume of the juice can is approximately 1804 cm³.

In a multiple regression analysis what would likely be the culprit of a dramatic increase in the P-value of one of the variables?

Answers

This can happen if you add another independent variable to your regression model that is strongly correlated to some other variable already in the model.
This is called multicollinearity. 
If there is a high correlation between your independent variables can lead to problems.
It can lead to increased variance of the coefficient estimates and make the estimates very sensitive to minor changes in the model.

The proof would be as follows:

Given: angle M congruent to angle X; angle N congruent to angle Y; YO congruent to NZ.

1. YZ=YO+OZ; reason: segment addition postulate (YZ is made up of YO and OZ).

2. ON=NZ+OZ; reason: segment addition postulate (ON is made up of NZ and OZ).

3. YO=NZ; reason: given.

4. ON=YO+OZ; reason: substitution (since NZ is congruent to YO, we substitute YO for NZ).

5. ON=YZ; reason: substitution (since YZ=YO+OZ, we substitute YZ for YO+OZ).

6. MNO is congruent to XYZ; reason: AAS (we have 2 sides and a non-included angle in each triangle congruent, which is the angle-angle-side theorem).

Answer:

Given is :

∠M≅∠X

∠N≅∠Y

YO≅NZ

We have to prove that ΔMNO≅ΔXYZ

Using segment addition postulate we get YZ=YO+OZ and ON=NZ+OZ and YO=NZ is already given. Using substitution of YO for NZ; we get ON=YO+OZ

Now substituting YZ for YO+OZ we get ON=YZ and also YZ=YO+OZ.

Now applying AAS we get ΔMNO is congruent to ΔXYZ because of angle-angle-side theorem as we have already proved that two sides are congruent and a non-included angle in each triangle is congruent.

What's the present value of $11,500 discounted back 5 years if the appropriate interest rate is 4.5%, compounded semiannually?

Answers

$1,500/(0.03)^10 = $1,116.14

General Idea:

We need to make use of the below formula to find the present value.

[tex] PV=\frac{FV}{(1+\frac{r}{n})^{nt}} \\ \\ Where:\\ FV \; is \; Future\; Value\; of \; money\\ r \; is\; Annual\; rate\; of\; interest\\ t\; is\; number\; of\; years\\ n\; is\; Number\; of\; periods\; based\; on\; compounding \; frequency [/tex]

Applying the Concept:

We are given the below information:

[tex] FV= \$11,500\\ \\ t=5\; years\\ \\ r=4.5 \%\\ \\ n=2\; (because\; given\; compounded\; semi-annually) [/tex]

We need to substitute the above information in the formula to find the Present value.

[tex] PV=\frac{11500}{(1+\frac{0.045}{2})^{2 \times 5}} =\frac{11500}{(1+0.0225)^{10}} =\frac{11500}{1.0225^{10}} \\ \\ PV \approx \$9206 [/tex]

CONCLUSION:

The present value of $11,500 discounted back 5 years if the appropriate interest rate is 4.5%, compounded semiannually is approximately 9206 dollars

Angle D is a vertical angle to F. The measure of D is 53° . What is the measure of F?

Answers

The measure of F is 53°
Final answer:

Angle F will have the same measure as angle D, which is 53°, because they are vertical angles and thus congruent.

Explanation:

The question asks about the measure of angle F given that it is a vertical angle to angle D, which measures 53°. In geometry, vertical angles (also known as opposite angles) are pairs of non-adjacent angles formed when two lines intersect. Vertical angles are congruent, which means they have the same measure. Therefore, since angle D is 53°, angle F, being its vertical angle, will also have a measure of 53°.

Angle D and angle F are vertical angles, which means they are congruent. If angle D measures 53°, then angle F will also measure 53°. This is because vertical angles are equal in measure.

What is the probability of flipping a coin six times in a row and getting three heads and three tails?

Answers

3/1 and 3/1 for both

Final answer:

The probability of flipping a coin six times and getting exactly three heads and three tails is calculated using the binomial formula and is found to be 31.25%.

Explanation:

The probability of flipping a coin six times and getting exactly three heads and three tails can be calculated using the binomial probability formula, which is P(x; n, p) = (n choose x) * p^x * (1-p)^(n-x), where 'n' is the number of trials, 'x' is the number of successes, and 'p' is the probability of success on any given trial.

In this instance, since we are flipping a fair coin, the probability 'p' of getting heads (success) on any single flip is 0.5. We want to find the likelihood of getting 'x' = 3 heads out of 'n' = 6 flips. Therefore, the equation becomes:

P(3; 6, 0.5) = (6 choose 3) * 0.5^3 * 0.5^(6-3)

The combination (6 choose 3) calculates the number of ways to choose 3 successes (heads) from 6 trials, which is 20. Plugging these values into the equation gives:

P(3; 6, 0.5) = 20 * (0.5^3) * (0.5^3) = 20 * (0.125) * (0.125) = 20 * 0.015625

This results in a probability of 0.3125, or 31.25%.

Therefore, the chance of flipping a coin six times and getting three heads and three tails is 31.25%.

The volume v of a right circular cone of radius r and height h is given by v = 1/3 pi r^2 h. suppose that the height decreases from 20 in to 19.95 in and the radius increases from 4 in to 4.05 in. compare the change in volume of the cone with an approximation of this change using a total differential.

Answers

V = (π/3)*r^2*h
dV = (π/3)*(2r*h*dr +r^2*dh)

The approximate change in volume is

.. = (π/3)*(8 - 0.8) = 7.2(π/3) . . . . . in^3

The actual change in volume is
.. (π/3)*(4.05^2*19.95 -4^2*20) = 7.229875(π/3) . . . . . in^3

The actual change in volume is slightly more than the linear approximation would suggest.

Suppose you have two credit cards. The first has a balance of $410 and a credit limit of $1,000. The second has a balance of $510 and a credit limit of $1,000. What is your overall credit utilization? 36% 56% 46% 16% 26%

Answers

The question asked for overall credit utilization, so instead of considering individual credit cards for computation, I will use the credit limits of two cards as if it is just one credit card. That will give me a total limit of $2000.

In the same way, I will add the balances of each card for a total of $920 and get the percentage of remaining balance:

(sum of balances of two cards) ÷ (sum of credit limits of two cards)

($410 + $510) ÷ ($1000 + $1000) =  0.46 or 46%

Note:

But I have an argument because isn't it that credit utilization is the "percentage used" of the credit limit and for that, I have to subtract 46% from 100% which is 54% and that is not an included in the option

 
Your have a balance of $410 on one card and $510 on the other. Together (add) this is a balance of $920. Your total credit limit is $2000 (add the limits of each card).

That means you use [tex] \frac{920}{2000} [/tex]. Percent means "out of 100" so we wish to write this fraction with 100 in the denominator (the bottom). We do this by dividing the top (numerator) and bottom (denominator) by the same number. Here we use 20. That gives us [tex]\frac{920}{2000}= \frac{46}{100} =46%[/tex]
