Answer:

Step-by-step explanation:

Answer:

(a) 36 points

(b) Pr(rolling a double number) ≅ 0.167

(c) Pr(a sum of 6 is rolled) ≅ 0.139

(d) Pr(a sum of 11 is rolled)  ≅ 0.056

(e) No.

Step-by-step explanation:

Sample space = {1,1  1,2  1,3  1,4  1,5  1,6  2,1  2,2  2,3  2,4  2,5  2,6  3,1  3,2  3,3  3,4  3,5  3,6  4,1   4,2  4,3  4,4  4,5  4,6  5,1  5,2  5,3  5,4  5,5  5,6  6,1  6,2  6,3  6,4  6,5  6,6}

(a) The number of points in the sample space is 36.

(b) Pr(rolling a double number) = \(\frac{6}{36}\)

                                                   = \(\frac{1}{6}\)  ≅ 0.167

(c) Pr(a sum of 6 is rolled) = \(\frac{5}{36}\) ≅ 0.139

(d) Pr(a sum of 11 is rolled) = \(\frac{2}{36}\)

                                           = \(\frac{1}{18}\) ≅ 0.056

(e) No. It is more likely to roll a sum of 6 than that a sum of 11.

Answer: 45%

Step-by-step explanation:

Discount = original price - selling price

= $9.20 - $5.06

Discount = $4.14

Discount Percent = discount x 100 / original price

= $4.14 x 100 / $9.20

= $414 / $9.20

Therefore,

Discount Percent = 45%

Step-by-step explanation:

Therefore, the missing expression in Step 1 is [-8 - 1] + (2 + 3).

In order to find the missing expression in Step 1, let's analyze the given steps and the final expression.

Step 1: ?

Step 2: -9 + 2 + 3

Step 3: -7 + 3

To find the missing expression in Step 1, we need to work backwards from Step 3 to Step 1.

In Step 3, the expression "-7 + 3" gives us a result of -4.

In Step 2, the expression "-9 + 2 + 3" gives us a result of -4.

So, the missing expression in Step 1 should also evaluate to -4 when performed correctly.

Let's check the available options:

[-10 + -1 + 2] + (2 + 3) = -11 + 2 + 5 = -4

[-8 - 1] + (2 + 3) = -9 + 5 = -4

[-10 + 1] + (2 + 3) = -9 + 5 = -4

[8 + 1] + (2 + 3) = 9 + 5 = 14

Out of the given options, only option 2, [-8 - 1] + (2 + 3), correctly evaluates to -4. Therefore, the missing expression in Step 1 is [-8 - 1] + (2 + 3).

Answer:

In mathematics, the logarithm is the inverse function to exponentiation. That means the logarithm of a given number x is the exponent to which another fixed number, the base b, must be raised, to produce that number x.

Step-by-step explanation:

It will take about 88.89 minutes for the two containers to have the same amount of solution.

Let's call the amount of time it takes for the two containers to have the same amount of solution "t" (in minutes).

During that time, bucket A will lose 12t gallons of solution, so it will have 1,600 - 12t gallons left.

Bucket B starts with 0 gallons and gains solution at a rate of 6 gallons per minute (since it is being filled at the same rate that bucket A is losing solution).

So we can set up an equation:

1,600 - 12t = 6t

Simplifying:

1,600 = 18t

divide though by 18

t = 88.89 minutes

So it will take about 88.89 minutes for the two containers to have the same amount of solution.

Step-by-step explanation:

use the slope formula

y2-y1 / x2-x1

Therefore, if Josh attends 1 group class per month, both membership plans will cost him a total of $37 per month.

In mathematics, the first 10 integers are referred to as the fundamental numbers. From 0 to 9, these foundational numbers are listed. The 0 to 9 range of basic integers includes 0 through 1, 2, 3, 4, 5, 6, 7 and 8.

Let's start by defining some variables. Let:

We can write the equations for the total cost of each plan as:

T1 = 35 + 2x

T2 = 34 + 3x

Since we know that the two plans end up costing the same total amount when Josh attends a certain number of classes in a month, we can set T1 equal to T2 and solve for x:

35 + 2x = 34 + 3x

35 = 34 + x

1 = x

So if Josh attends 1 group class per month, the two membership plans will cost the same total amount. Let's substitute x = 1 into our equations for T1 and T2 to find out what that total amount is:

T1 = 35 + 2(1) = 37

T2 = 34 + 3(1) = 37

Therefore, if Josh attends 1 group class per month, both membership plans will cost him a total of $37 per month.

There are 2000 grams of in each meal.

Step-by-step explanation:

First you divide 8 by 4 because that's how many meals he eats per day then you convert the kilograms into grams.

The weight of each meal a black bear eats is 2 kilograms.

A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.

Given,  A black bear in a zoo eats 8 kilograms of food each day.

He eats 4 equal-sized meals each day.

∴ The weight of each meal is the total kilograms of food divided by the total no. of meals which is,

= (8/4) kilograms.

With 99% confidence that the true difference lies between 0.1316 and 0.2694.

A 99% confidence interval for the difference in average SAT scores between coached and uncoached students can be constructed using the data above.

The confidence interval is calculated as (mean of coached students - mean of uncoached students) +/- (2 * standard error of the difference in means).

The mean of coached students is (0.3098 + 0.3399 + 0.219 + 0.0798) / 4 = 0.2155, and the mean of uncoached students is (0.0046 + 0.0248) / 2 = 0.0147. The standard error of the difference in means can be calculated as the square root of ((0.2155(1-0.2155)/4) + (0.0147(1-0.0147)/2)).

The confidence interval is then (0.2155 - 0.0147) +/- (2 * 0.0347) = 0.201 +/- 0.0694, or (0.1316, 0.2694). This indicates that, on average, coached students gain 0.201 points more than uncoached students, with 99% confidence that the true difference lies between 0.1316 and 0.2694.

When matched, the prompts on asymptotes would be:

The presence of a vertical asymptote at x=0 signifies that the cost of producing pills can never reach a value of 0, remaining persistently positive. Simultaneously, the horizontal asymptote at y=0 serves as a reassuring indication that the cost of producing pills cannot be negative, as it steadfastly remains at or above zero.

This crucial constraint ensures that the cost incurred in the pill production process is always a non-negative quantity. Consequently, the prompt related to the impossibility of negative costs aligns with this notion.

The solution for this system of equations is equal to 5 and 80.

Based on the information provided above, Sebastian is using a 20-kilogram bar, increasing the amount of weight he lifts by 12 pounds on each set. Therefore, the total weight, y, can be represented by this equation:

y = 12x + 20  .......equation 1.

x represents the number of set.

For his partner, using a 40-kilogram bar, increasing the amount of weight he lifts by 8 pounds on each set. Therefore, the total weight, y, can be represented by this equation:

y = 8x + 40

By equating equation 1 and equation 2, we have the following:

8x + 40 = 12x + 20

4x = 20

The measure of the central angle is 0.75 radians

An equation is an expression that can be used to show the relationship between two or more numbers and variables using mathematical operators.

The area of a figure is the amount of space it occupies in its two dimensional state.

The length of an arc with an angle of Ф is given by:

Length of arc = (Ф/360) * (π * diameter)

The diameter is 16 cm and intercepted arc length is 6 cm, hence:

Length of arc = (Ф/360) * (π * diameter)

6 = (Ф/360) * (π * 16)

Ф = 42.97°

Ф = 42.97° * π/180 = 0.75 radian
