Can you please answer the question???

Answer:

Below

Step-by-step explanation:

rate X time = distance

rate  = distance / time    <=====we want minimum of this so make denominator as large as possible and numerator as small as possible

      distance = 595  KM    ( rounds up to 600 km)

        time = 8 hr 44 min  rounds down to 8 :40    you could make it 8:44.99)

595 km / (8 + 44.99/60) hr  = 68 km/hr

John can buy any amount of chocolate between 0 and 2.2 pounds (rounded to one decimal place) and still have enough money to buy the jelly beans.

John brings $15 to the candy store and buys a bag of jelly beans for $4. He plans to buy some chocolate that costs $5 per pound. Let x be the number of pounds of chocolate John could buy.

The cost of the chocolate John plans to buy is $5 per pound, so the total cost of x pounds of chocolate is 5x. John's total budget is $15, so he must have enough money to buy the jelly beans and the chocolate. Therefore, the inequality that represents this situation is:

4 + 5x ≤ 15

To solve for x, we can begin by isolating the variable on one side of the inequality. We can do this by subtracting 4 from both sides of the inequality:

5x ≤ 11

Next, we can isolate x by dividing both sides of the inequality by 5:

x ≤ 11/5

Therefore, the possible values of x, the number of pounds of chocolate John could buy, are all real numbers less than or equal to 11/5. However, since John cannot buy a negative amount of chocolate, we must also restrict x to be greater than or equal to 0. Therefore, the solution to the inequality is:

0 ≤ x ≤ 11/5

Answer:

4x * -16

Step-by-step explanation:

You use the distributive property and multiply 4 by everything in the parentheses. The 16 is negative because you keep the minus sign with the number behind it.

Answer:

k = 48.4

Step-by-step explanation:

[tex] \frac{k - 16}{6} = 5.4 \\ 6 \times \frac{(k - 16)}{6} = 5.4 \times 6 \\ k - 16 = 32.4 \\ k = 32.4 + 16 \\ k= 48.4 [/tex]

The vertex of the parabola is (0, -8).

A parabola is a plane curve which is mirror-symmetrical and is approximately U-shaped.

We have to find the vertex of the parabola y = x² - 8,

x = -b/2a

where a is the coefficient of the x² term,

b is the coefficient of the x term, and

x is the x-coordinate of the vertex.

a = 1 and b = 0, so:

x = -0/(2.1) = 0

Now let us find the y-coordinate of the vertex, we can substitute x = 0 into the equation for the parabola:

y = (0)² - 8 = -8

Hence, the vertex of the parabola is (0, -8).

Point H is located at 6 on the number line, which is 6 units to the right of the zero point.

We know that Point G is located at-18 on the number line, and that Point H is 24 further than Point G. To find the position of Point H, we need to add 24 to the position of Point G

Point H = Point G + 24

Substituting the position of Point G, we get

Point H = -18 + 24

Simplifying the expression, we get

Point H = 6

thus, Point H is located at 6 on the number line.

The correct option is "the standard error is the standard deviation of the sampling distribution." Correct option is A.

The standard error is a measure of the variability of a sampling distribution, which is the distribution of sample statistics (e.g., mean, proportion) that would be obtained from multiple random samples of the same size from the same population.

The standard error represents the standard deviation of the sampling distribution, and it provides a measure of the precision of the sample statistic in estimating the population parameter.

The standard error is not the same as the standard deviation of the sample, which is a measure of the variability of the individual observations in the sample.

The standard deviation of the sample is typically used to estimate the standard deviation of the population, while the standard error is used to estimate the variability of the sample statistic and to construct confidence intervals or perform hypothesis tests.

While the other options are related to the concept of the standard error, they are not equivalent or fully accurate descriptions of what the standard error represents.

Using an equation, the bride-to-be and her maid of honor will each have made 25 favors in 5 minutes.

An equation is a mathematical statement showing that two or more mathematical expressions are equal or equivalent.

Equations are depicted using the equal symbol (=), while mathematical expressions, which combine variables, constants, and values only use mathematical operands.

The total number of wedding favors assembled by the bride-to-be = 15

The bride's assembling rate per minute = 2 favors

The maid of honor's assembling rate per minute = 5 favors

Let x = the number of minutes used

Let the number of favors assembled by the bride = 15 + 2x

Let the total number of favors assembled by the maid of honor = 5x

For the two to assemble the same number of favors, 15 + 2x = 5x

15 = 3x

5 = x

Thus, in 5 minutes the bride-to-be and her maid of honor will have assembled 25 favors each.

Sidney will use 54 cups of soda for 17 cups of ice cream, So the answer is 54 cups.

What is the ratio?

A ratio is a relationship between two things when it is expressed in numbers or amounts. For example, if there are ten boys and thirty girls in a room, the ratio of boys to girls is 1:3, or one to three.

We can start by noticing that the ratio of cups of ice cream to cups of soda used to make the floats is always 1:3.

To find out how much soda Sidney will use for 17 cups of ice cream, we can set up a proportion:

3.5/10.5 = 8/24 = 12.5/37.5 = 17/x

Solving for x, we can cross-multiply:

3.5x = 10.5 * 17

x = 54

Therefore, Sidney will use 54 cups of soda for 17 cups of ice cream, So the answer is 54 cups.

The probability that the first n coupons which you collect do not form a complete set is (c^n - (c-1)^n) / c^n.

To find the probability that the first n coupons collected do not form a complete set, we need to count the number of ways in which the first n coupons can be collected so that they do not form a complete set and divide it by the total number of ways in which n coupons can be collected, which is c^n.

Let S be the set of all possible complete sets of coupons. The number of ways in which the first n coupons can form a complete set is the number of ways to choose any one of the complete sets in S, multiplied by the number of ways to order the coupons within that set. There are (c choose n) ways to choose n coupons out of c, and for each complete set of n coupons, there are n! ways to order them. Therefore, the number of ways to choose n coupons that form a complete set is (c choose n) * n!.

The total number of ways to choose n coupons out of c is c^n.

So, the probability that the first n coupons collected do not form a complete set is:

P = 1 - [(c choose n) * n! / c^n]

Alternatively, we can count the number of ways in which the first n coupons can be collected so that they do form a complete set. There are (c-1)^n ways to choose n coupons out of c-1 types of coupons, and for each set of n coupons, there is exactly one way to add the missing coupon to form a complete set. Therefore, the number of ways to choose n coupons that form a complete set is c^n - (c-1)^n.

So, the probability that the first n coupons collected do not form a complete set is:

P = (c^n - (c-1)^n) / c^n

The value of x for the similar triangles is equal to 13.

We have the triangles to be similar, this implies that the length 8 of the smaller triangle is similar to the length x - 1 of the larger triangle

and the length 10 of the smaller triangle is similar to the length x + 2 of the larger triangle

so;

10/(x + 2) = 8/(x - 1)

10(x - 1) = 8(x + 2) {cross multiplication}

The linear equation for A and B will be A=1000+35t and B=700+55t where t=no. of years and A will be same as B in 15 years.

What exactly is a linear equation?

The equation is referred to as linear when a variable's maximum power is 1. A one-degree equation is another name for it. A linear equation in one variable has the conventional form Ax + B = 0. This equation has three variables: x, A, and B. A is a coefficient. A linear equation in which there are only two variables typically takes the form Ax + By = C. In addition to the constant C, there are three other constants: the variables x and y, the coefficients A and B, and the variables.

Now,

As given that High School A currently has 1000 students and is projected to grow by 35 students each year. High School B currently has 700 students and is projected to grow by 55 students each year.

Let A represent the number of students in High School A in t years, and

Let B represent the number of students in High School B after t years.

Then A=initial students+35*no. of years and B=initial students+55*no. of years i.e. A=1000+35t and B=700+55t  

and for A=B

1000+35t=700+55t

55t-35t=1000-700

20t=300

t=15

hence,
