Answer:

(9,2) and (-6,2).

Step-by-step explanation:

Rectangular Coordinates

The lower vertices of a rectangular welcome sign in Mr. Brettler's gym are (9,-3) and (-6,-3).

Note these two vertices are 3 units below the x-axis. We know the sign is 5-foot tall, so the y-coordinates of the two upper vertices should be -3+5=2.

The upper vertices of the sign on the grid are (9,2) and (-6,2).

Step-by-step explanation:

If student has a container with a volume of 2.5 liters. She estimates the volume to be 2.4 liters. Then by 4% the student's estimate off

percentage, a relative value indicating hundredth parts of any quantity.

Given,

The container of a student has a volume of 2.5 liters.

She estimates the volume to be 2.4 liters

We need to find the percent of  student's estimate off.

To find this we have to find the difference of 2.5 and 2.4

2.5-2.4=0.1

Now divide zero point one divided by two point five

0.1/2.5

0.04

Multiply with hundred

0.04×100=4%

Hence 4 % is the students estimate off

Answer:

The correct answer is "[tex]x=\frac{1}{4}[/tex]" and "[tex]y=-\frac{1}{2}[/tex]"

Step-by-step explanation:

As we know,

y = -2x ...(equation 1)

y = 2x-1 ...(equation 2)

On putting the value of "equation 1" in the "equation 2", we get

⇒ [tex]y=2x-1[/tex]

⇒ [tex]-2x=2x-1[/tex]

On adding "2x" both sides, we get

⇒ [tex]-2x+2x=2x-1+2x[/tex]

⇒ [tex]0=4x-1[/tex]

⇒ [tex]4x=1[/tex]

⇒  [tex]x=\frac{1}{4}[/tex]

Now,

On putting the value of "x" in equation 1, we get

⇒ [tex]y=-2x[/tex]

⇒ [tex]y=-2\times \frac{1}{4}[/tex]

⇒ [tex]y=-\frac{1}{2}[/tex]

The answer is below

Step-by-step explanation:

Coterminal angles are angles with the same terminal side at standard position (angles with the initial side on the positive x-axis).  Coterminal angles may have different magnitude but they would have equal sides and vertices.

Coterminal angles can either be positive or negative. The positive coterminal is gotten by adding 2π rad or 360° while the negative coterminal is gotten by subtracting 2π rad or 360°.

a)

Positive coterminal angle = [tex]\frac{5\pi}{4}+2\pi=\frac{13\pi}{4} \ rad[/tex]

Negative coterminal angle = [tex]\frac{5\pi}{4}-2\pi=\frac{-3\pi}{4} \ rad[/tex]

b)

Positive coterminal angle = [tex]\frac{-9\pi}{4}+2\pi=\frac{-\pi}{4}+2\pi=\frac{7\pi}{4} \ rad[/tex]

Negative coterminal angle = [tex]\frac{-9\pi}{4}-2\pi=\frac{-17 \pi}{4} \ rad[/tex]

Answer:

Number of black counters = 5

Step-by-step explanation:

Let,

x be the total number of counters

Number of red counters = [tex]\frac{1}{3}x[/tex]

Number of black counters = [tex]\frac{1}{6}x[/tex]

Number of green counters = 15

Now,

Red counters + Black counters + Green counters = Total counters

[tex]\frac{1}{3}x+\frac{1}{6}x+15=x\\\\\frac{2x+x+90}{6}=x\\\\3x+90 = 6x\\90 = 6x-3x \\90 = 3x\\3x = 90[/tex]

Dividing both sides by 3

[tex]\frac{3x}{3}=\frac{90}{3}\\x=30[/tex]

Number of black counters = [tex]\frac{1}{6}*30[/tex] = 5

Hence,

Number of black counters = 5

Answer: 17.3 in 2

Step-by-step explanation

The approximate area of the shaded sector is 34.6 in2.

Surface area are derived for some standard shapes like circle, triangle, parallelogram, rectangle, trapezoid, etc.

When some shape comes which isn't standard figure, then we find its area by slicing it (virtually, like by drawing lines) in standard shapes. Then we calculate those composing shapes' area and sum them all.

Thus, we have:

[tex]\text{Area of composite figure} = \sum (\text{Area of composing figures})[/tex]

That ∑ sign shows "sum"

We are given that;

Angle = 145°

Now,

The area of a sector of a circle is given by the formula A = (θ/360)πr2, where θ is the central angle in degrees and r is the radius of the circle. In this case, θ = 145° and r = 7 in.

Plugging these values into the formula, we get: A = (145/360)π(7)^2. Simplifying, we get: A = 0.4028π(49). Using a calculator, we get: A ≈ 34.6 in2.

Therefore, by the area the answer will be 34.6 in2.

Answer:

a) The 99% confidence interval of the population average of drug dosage dispensed is between 23.1 mg and 25.1 mg.

b) It means that we are 99% sure that the true mean dosage for all the population is between 23.1 mg and 25.1 mg.

Step-by-step explanation:

We have the standard deviation for the sample, so we use the t-distribution to solve this question.

a)

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 25 - 1 = 24

99% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 24 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.99}{2} = 0.995[/tex]. So we have T = 2.797

The margin of error is:

[tex]M = T\frac{s}{\sqrt{n}} = 2.797\frac{1.8}{\sqrt{25}} = 1[/tex]

In which s is the standard deviation of the sample and n is the size of the sample.

The lower end of the interval is the sample mean subtracted by M. So it is 24.1 - 1 = 23.1 mg

The upper end of the interval is the sample mean added to M. So it is 24.1 + 1 = 25.1 mg

The 99% confidence interval of the population average of drug dosage dispensed is between 23.1 mg and 25.1 mg.

b)

The interval means that we are 99% sure that the true mean dosage for all the population is between 23.1 mg and 25.1 mg.

Answer:

Explanation below, despite missing details in question.

Step-by-step explanation:

The function isn't given but we know it's labelled "f".

The inverse of a function (likewise the inverse of any other quantity) is simply the function turned up-side-down.

To invert a function, you switch the places of both numerator and denominator. Example:

f = [tex]\frac{x}{y}[/tex]

the inverse of the function above is y/x

If the function is not in fraction form or doesn't have a visible denominator, take the denominator to be 1.

The denominator of every number or function is 1, so you'll be correct doing this.

If  f = 2n +5  then the inverse of f will be  [tex]\frac{1}{2n + 5}[/tex]

NOTE: Inverse of f  ≡ 1/f  ≡  [tex]f^{-1}[/tex]
