[tex] 99.12[/tex] is the answer.

Step-by-step Explanation:

To find- Probability area bound by 93% or 0.93.

Steps-

0.5 lies to the lie of the mean value.

→ 0.93 - 0.5 = 0.43 lies to the right of the mean.

Now find the corresponding "z" value for 0.43

It is 1.48.

Use this value to determine the requix value.

You have to use the formula -

[tex]z = x - μσ[/tex]

Solve it for [tex]x[/tex]:-

[tex]x = z \times σ + μ[/tex]

Where;

[tex]x = ? \\ z = 1.48 \\ σ = 0.62 \\ μ = 98.20[/tex]

Now put these values in the

formula;

[tex]x = (1.48 \times 0.62) + 98.20[/tex]

[tex] = > 0.9176+98.20[/tex]

[tex] = > 99.1176[/tex]

[tex] = > 99.12[/tex]

Hence, the temperature that separates

top 7% from the bottom 93%

is 99.12.

Answer:

The temperature that separates the top 7% with the bottom 93% is 99.12 degrees.

Step-by-step explanation:

(x - 98.2) / 0.62 = 1.48

x - 98.2 = 0.9176

x = 99.12 degrees

5.7 is the answer I had the same question in my test

Answer: 171/4, and 14.25

Step-by-step explanation:

We can solve this by first finding the area of each piece of fabric. Area is width multiplied by height, so:

3 * (4+3/4) = 57/4

We can multiply our answer by 3 again to find the total area.

57/4 * 3 = 171/4

To find the fabric as a decimal, we can first put it as a mixed fraction

[tex]14\frac{1}{4}[/tex]

This becomes 14.25

Answer: A

Step-by-step explanation:

C lies below g(x) and f(x), so we need [tex]f(x) \leq 3x+4[/tex] and [tex]g(x) \leq -\frac{1}{2}x-5[/tex].

Answer:

I'm not sure what the question was but I've worked out all the three types of trees

Step-by-step explanation:

⅓ + ⅕ = 8/15 because:

×5 ×3

5/15 + 3/15 = 8/15

therefore 7/15 is fig trees

90÷15 =6

6×5 = 30 apple trees

6×3 = 18 lemon trees

6×7 = 42 fig trees

Answer:

48

Step-by-step explanation:

We must first find what is 75% of 64 (x), in order to find what this number is 120% of (y).

To find percentages, we can use the formula[tex]\frac{is}{of}=\frac{p percent}{100}[/tex], and we cross multiply and divide to find either the is value, of value, or the percent.

Thus, we have[tex]\frac{x}{64}=\frac{75}{100}\\ \\ 100x=(64*75)\\\\\frac{(100x=(64*75))}{100} \\\\x=48[/tex]

Now we want to find what 48 is 120% of:

[tex]\frac{48}{y}=\frac{120}{100} \\\\ 120y=(48*100)\\\\[/tex]

[tex]\frac{(120y=(48*100)}{120} \\\\y=40[/tex]

Answers:

See the diagram below.

======================================

Explanation:

Let's say we replaced 3x with y for now.

3x+1 is the same as y+1

So we have y+1 = 10

To isolate y, we undo the addition and subtract 1 from both sides.

That means -1 will go in the first two boxes.

---------------------------------------

After that step is done, we have y = 9 which is the same as 3x  = 9 after replacing y with 3x.

3x means "3 times x".

To undo the multiplication, we divide both sides by 3.

Therefore, boxes 3 and 4 will have "3" each.

----------------------------------------

Box 5 has 3 as well because 9/3 = 3.

The final answer is x = 3.

As a check,

3x+1 = 10

3*3+1 = 10

9+1 = 10

10 = 10

It works out.

Refer to the diagram below.

Answer:

40%

Step-by-step explanation:

Total amount is 15

6 out of the 15 amount are apples

Thus, 6/15 x 100 = 40%

Or

You could ask yourself, what number do I multiply by 15 to get to 100?

Then, multiply the top (numerator) by it.

The value of the numerator will give you the final % (percentage) due to percentage being out of 100.

Hope this helps!

Step-by-step explanation:

The only integer divisors of 2 are 1 and 2. (2 is a prime number, divisible only by 1 and itself.) When listed according to the instructions, they can be positive or negative:

  2 = (-2×-1) = (1×2)

Pairs of integer factors are (-2, -1) and (1, 2).

Answer: See below

Step-by-step explanation:

A) [tex]-x+2y < -4[/tex]

[tex]-x+2y-2y < -4-2y[/tex]

[tex]-x < -4-2y[/tex]

Multiply both sides by -1 and reverse the inequality:

[tex]\left(-x\right)\left(-1\right) > -4\left(-1\right)-2y\left(-1\right)[/tex]

[tex]x > 4+2y[/tex]

B) [tex]2x+3y > 6[/tex]

[tex]2x+3y-3y > 6-3y[/tex]

[tex]2x > 6-3y[/tex]

[tex]\frac{2x}{2} > \frac{6}{2}-\frac{3y}{2}[/tex]

[tex]x > \frac{6-3y}{2}\\x > 3-\frac{3y}{2}[/tex]

Answer:

d = 0

Step-by-step explanation:

1d+2d=3d−4d

Combine 1d and 2d to get 3d.

3d=3d−4d

Combine 3d and −4d to get −d.

3d=−d

-

Add d to both sides.

3d+d=0

Combine 3d and d to get 4d.

4d=0

-

Product of two numbers is equal to 0 if at least one of them is 0. Since 4 is not equal to 0, d must be equal to 0.

d = 0

Answer:

d = 0

Step-by-step explanation:

1d + 2d = 3d - 4d

d + 2d = 3d - 4d

combine:

d + 2d = 3d

3d - 4d = -d

equals - 3d = -d

add d to both sides

3d + d = -d + d

Simplify :

4d = 0

Divide both sides of the equation by the same term:

4d/4 = 0/4

d = 0/4

so the answer is d = 4

Step-by-step explanation:

160/-5 = -32

Using confidence interval concepts, it is found that the interval estimate is (0.274, 0.364), and it means that we are x% sure(considering the confidence level) that the proportion of all voters in the city that plan to vote for the Democratic candidate is between these two values.

It is given by the sample proportion plus/minus the margin of error, and a x% confidence interval means that we are x% sure the population proportion is in the interval.

134 of 420 randomly chosen likely voters indicated that they planned to vote for the Democratic candidate, hence:

p = 134/420 = 0.319

The margin of error for the statistic is 0.045, hence:

0.319 - 0.045 = 0.274

0.319 + 0.045 = 0.364

The interval estimate is (0.274, 0.364), and it means that we are x% sure(considering the confidence level) that the proportion of all voters in the city that plan to vote for the Democratic candidate is between these two values.
