Answer:

[tex](x_1,y_1) = (0,9)[/tex]

[tex](x_2,y_2) = (6,3)[/tex]

[tex](x_3,y_3) = (6,12)[/tex]

Step-by-step explanation:

Given

x = hours spent on cardiovascular work

y = hours spent on weight training

From the first statement,

Each week: he spends at least 9 hours

This is represented as:

[tex]Total \ge 9[/tex]

[tex]x + y \ge 9[/tex]

From the second statement,

Each week: he spends a max of 12 hours on weights

This is represented as:

[tex]Weight \le 12[/tex]

[tex]y \le 12[/tex]

From the third statement,

Each week: he spends a max of 6 hours on cardio works

This is represented as:

[tex]Cardio \le 6[/tex]

[tex]x \le 6[/tex]

So, the inequalities are:

[tex]x + y \ge 9[/tex]

[tex]y \le 12[/tex]

[tex]x \le 6[/tex]

See attachment for the graph where the solution are also highlighted

From the attachment, the solutions are:

[tex](x_1,y_1) = (0,9)[/tex]

[tex](x_2,y_2) = (6,3)[/tex]

[tex](x_3,y_3) = (6,12)[/tex]

Answer:

[tex]\frac{6\\}{25}[/tex]

Answer:  15 units .

__________________________________________________

In this case, a square, the two sides of the square (forming a right triangle) are equal), and the "diagonal" forming is the hypotenuse of the right triangle.

In these cases, the measurements of the angles of the right triangle are "45, 45, 90" ; and the measurements of the sides are:  "a, a, a√2" ; in which "a√2" is the hypotenuse.

We are given:  "15√2" is the hypotenuse" ; and we are given that this is a right triangle of a square with a diagonal length (i.e. "hypotenuse" of "15√2" ; so the measure of the side of the "square" (and other two sides of the triangle formed) is:  15 units.   (i.e.,  15, 15, 15√2 ).

Answer:

2/5 remaining

Step-by-step explanation:

If a job is 35 and 3/5 was completed, 3/5 of 35 = 21

That is 35 - 21 = 14

The fraction of the job remaining to be done will then be 14/35 = 2/5

Answer:

Pretty sure it's 17 ducks.

The correct answer is based on the information given, we can estimate  by probability that there are approximately 9 ducks with red marks on the bottom out of the 150 ducks in the pool.

To estimate the number of ducks with red marks on the bottom, we can use the information given: out of 50 people playing the game, only 3 have won a small prize.

We can assume that the probability of winning a small prize is the same for each player, and that each duck is equally likely to have a red mark.

If only 3 out of 50 people have won a small prize, we can estimate that the probability of winning is approximately 3/50.

Let's denote the number of ducks with red marks as "x." The probability of winning a small prize can be represented as x/150 (since there are 150 ducks in total).

Setting up the equation:

x/150 = 3/50

To solve for x, we can cross-multiply:

50x = 3 * 150

50x = 450

Dividing both sides by 50:

x = 9

Therefore, based on the information given, we can estimate  by probability that there are approximately 9 ducks with red marks on the bottom out of the 150 ducks in the pool.

Answer:

A

Step-by-step explanation:

Part A, A. Kari, because the mean and median of her scores is, 84.5.

Part B, Jocely will see a greater increase overall as her previous average is less.

The three main methods for identifying the average value of a set of integers are mean, median, and mode.

Adding the numbers together and dividing the result by the total number of numbers in the list yields the arithmetic mean.

The middle value in a list that is arranged from smallest to greatest is called the median.

The value that appears the most frequently on the list is the mode.

From the given information, The average score of Jocelyn is,

= (86 + 87 + 95 + 72 + 78 + 80)/6.

= 83.

And Similarly, The average score Kari is,

= (88 + 78 + 93 + 81 + 75 + 91)/6.

= 84.5.

Therefore, Kari scores better overall.

If they both get 90% on their next math quiz Jocely will see a greater increase overall as her previous average is less.

Answer:

9,160,000 tons

Answer:

D

Step-by-step explanation:

hope it helps u

The statement is the quotient of 32 and 4 added to the product of fraction 1 over 2 and 16, then subtract 2 describes the expression 32 ÷ 4 + (1/2 x 16) - 2.

The given expression is "32 ÷ 4 + (1/2 x 16) - 2".

"32 ÷ 4" is the division of 32 by 4, which results in the quotient of 8. So, the first part of the expression simplifies to 8.

"(1/2 x 16)" is the product of the fraction 1/2 and 16.

Multiplying these values gives us 8.

Now, we have "8 + 8 - 2". Adding 8 and 8 gives us 16.

Subtracting 2 from 16 results in a final value of 14.

Therefore, the expression "32 ÷ 4 + (1/2 x 16) - 2" simplifies to 14.

Step-by-step explanation:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1 - 0.99}{2} = 0.005[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].

That is z with a pvalue of [tex]1 - 0.005 = 0.995[/tex], so Z = 2.58.
