What is 42−6×4(12) to the third power?

Answers

Answer 1

Answer:

Step-by-step explanation:

First, we need to evaluate the expression inside the parenthesis: 4(12) = 4 * 12 = 48.

Next, we can simplify the expression: 42 - 6 * 48 = 42 - 288 = -246.

Finally, we raise the result to the third power: (-246)^3 = (-246) * (-246) * (-246) = -158,048.

So, the result is -158,048.

The baker made a batch of chocolate chip, oatmeal raisin, and sugar cookies. If P(chocolate chip) = 0.50, interpret the likelihood of randomly selecting a chocolate chip cookie from the batch.

A. Equally likely and unlikely
B. Likely
C. Unlikely
D. This value is not possible to represent probability of a chance event.

Answers

The probability that it is likely that a randomly selected cookie from the batch will be a chocolate chip cookie.

What is probability?

Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

If P(chocolate chip) = 0.50, it means that the probability of randomly selecting a chocolate chip cookie from the batch is 0.50 or 50%.

Interpreting this probability, we can say that it is likely that a randomly selected cookie from the batch will be a chocolate chip cookie since the probability is relatively high.

Therefore, the correct answer would be an option (B) Likely.

Lamar and Allie are organizing a car wash to raise money to buy new hockey sticks for their school's hockey team. The number of hockey sticks they will be able to purchase for the team depends on the number of cars they wash.

s = the number of hockey sticks Lamar and Allie will be able to purchase
c = the number of cars Lamar and Allie wash

Which of the variables is independent and which is dependent?

Answers

The independent variable of the question is c:the number of cars Lamar and Allie wash while the dependent variable is s: the number of hockey sticks Lamar and Allie will be able to purchase

How to find the independent and dependent variables?

The independent variable is defined as the variable that you change and control in your experiment. The dependent variable is defined as the variable that you don't have control over and is affected by the way that the independent variable reacts.

The parameters given are;

s = the number of hockey sticks Lamar and Allie will be able to purchase

Best buy is having a 15% off sale on all brands of computers. Jerome buys a computer regularly priced at $2250. How much does jerome save on the computer? if the sales tax is 7. 5%what is the amount of tax on the computer? how much is the total cost for the computer? what would be the total price for the computer not on sale?

Answers

Jerome saves 337.5$ on the computer.

Jerome buys the computer for 1912.5$.

The total cost of the computer is 2056$ including sales tax.

The total price of the computer not on sale is 2418.75$.

The discount is 15% of the original price:

0.15 x $2250 = $337.50.

If the sales tax is 7.5%,

The price of the computer after the discount is $2250 - $337.50 = $1912.50.

The amount of tax on the computer is 7.5% of $1912.50:

0.075 x $1912.50 = $143.44.

The total cost for the computer is the discounted price plus the tax: $1912.50 + $143.44 = $2055.94.

The total price for the computer not on sale would be the original price plus the tax:

$2250 + $169.13 = $2419.13 (where tax is 7.5% of $2250).

In February, Dawn's monthly allowance and Evelyn's monthly allowance were in the ratio 5: 8. In March, Mother increased Dawn's monthly allowance by 20% and decreased Evelyn's monthly allowance. Dawn and Evelyn then had the same amount of allowance. What was the percentage decrease in Evelyn's allowance in March?

Answers

Answer:

25%

Step-by-step explanation:

Let Dawn’s monthly allowance be 5x. Let Evelyn’s monthly allowance then be 8x.

Percentage increase by 20% is the same as multiplying a number by 1.2

To find the percentage decrease of Evelyn’s monthly allowance, we can equate their allowances after the change of their initial allowance.

1.2 * 5x = k/100 * 8x

k represents the percentage

6x = 8xk/100

Cancel the x’s from both sides

6 = 8k/100

600 = 8k

k = 75

Therefore since 75% of Evelyn’s monthly allowance is equal to Dawn’s increased monthly allowance, this means Evelyn’s monthly allowance was decreased by 25%.

Answers

Mei concluded that

We are 90% confident that the true proportion of times the die would land on the number 4 is between 0.398 and 0.562. Since this includes 0.5, the die appears to be fair.

It is based on a statistical analysis of the data collected by Mei.

The proportion of times the die landed on the number 4 is calculated as 48/100 = 0.48.

Using a statistical method called a confidence interval, we can estimate the range of values that the true proportion of times the die would land on the number 4 is likely to fall within, with 90% confidence.

The confidence interval calculated for this data is 0.398 to 0.562.

Since this interval includes the value of 0.5 (which would be the proportion of times a fair die would land on the number 4), By using statistical method we cannot reject the hypothesis that the die is fair.

Hence,

By using statistical method, we can conclude that the die would land on the number 4 is between 0.398 and 0.562 as 0.5 the die appears to be fair.

Sarah's cell phone company charges her $35 a month for phone service plus $0.25 for
every text message. How many text messages does Sarah send in one month if her bill
was $99?

Answers

Answer:

256 text

Step-by-step explanation:

Let's call the number of text messages Sarah sends in a month as "x".
So, the total cost of the text messages is $0.25 * x.

The total cost of the phone service and text messages is $35 + $0.25 * x = $99.

So, $35 + $0.25 * x = $99.

Subtracting $35 from both sides, we have:$0.25 * x = $99 - $35 = $64

Dividing both sides by $0.25, we have:x = 256

So, Sarah sent 256 text messages in one month.

Answers

Answer:

x = 2 and y = -4

Step-by-step explanation:

To solve using substitution, we define one unknown variable in terms of another and sub this into a second equation with both.

We are told y=2x-8 and -3x+4y=-22, so let's sub '2x-8' in for y in -3x+4y=-22:

-3x+4y=-22

-3x+4(2x-8)=-22

-3x+8x-32=-22

5x=10

x=2

If x=2 and y=2x-8, let's sub 2 in for x to find y:

y=2x-8

y=2(2)-8=4-8=-4

Swing arcs on both sides to intersect the first two arcs created.
Swing an arc that intersects the segment.
Swing arcs that intersect a point that is not on the segment.
Swing an arc that intersects the opposite endpoint.

Answers

When bisecting a segment using a compass, Sasha's next step would be to swing an arc that intersects the segment. Correct option is B.

To bisect a segment, Sasha needs to find the midpoint of the segment. The compass can help her achieve this by creating two arcs with the same radius from each endpoint of the segment. The intersection of these arcs will be the midpoint of the segment.

Sasha's first step is to place the compass on one endpoint of the segment and open it to a width larger than the length of the segment. Then, she places the compass on the other endpoint and draws an arc that intersects the first arc.

The next step is to swing an arc with the same radius from the other endpoint of the segment, again intersecting the first arc. The intersection of these two arcs will give the midpoint of the segment, which can be marked with a straightedge.

Therefore, Sasha's next step in bisecting a segment using a compass is to swing an arc that intersects the segment.

sufficient and necessary? 1 point possible (graded) suppose that we have some loss function that may or may not have multiple critical points. we have found a critical point such that f''(w)>0 , so that we know that it is a minimum. what can we say about it being a global minimum?

Answers

In order to determine whether a critical point of a loss function is a global minimum, it is necessary to consider the second derivative of the function.

If the second derivative is positive at the critical point, then we can say with certainty that the critical point is a local minimum. However, this does not necessarily mean that it is a function function. This is because there may be other local minima at points which the second derivative is negative, and in this case, the critical point must be compared to these points to determine if it is indeed the global minimum.

In order to assess whether a local minimum is a global minimum, we must first identify any other local minima. This can be done by locating the points at which the first derivative of the function is equal to zero and then evaluating the second derivative of the function at these points. If the second derivative is negative at any of the points, then we have identified a local minimum. Then, we can compare the value of the loss function at the points function as local minima to the value of the loss function at the critical point. If the value of the loss function at the critical point is lower than the value of the loss function at the other local minima, then the critical point is the global minimum. If the values are equal, then the critical point is a global minimum if and only if it is the only local minimum.Overall, identifying whether a critical point of a loss function is a global minimum requires both sufficiency and necessity. It is necessary to evaluate the second derivative of the function at the critical point in order to determine whether it is a local minimum, and it is also necessary to identify any other local minima and compare the value of the loss function at the critical point to the value of the function at the other local minima in order to determine whether the critical point is the global minimum.
