Answer:

7i.

Step-by-step explanation:

Note : The given expression must be [tex]\sqrt{-49}[/tex].

We have to write this radical value in the imaginary value.

The given value can be rewritten as

[tex]\sqrt{-49}=\sqrt{49\times (-1)}[/tex]

[tex]\sqrt{-49}=\sqrt{49}\times \sqrt{-1}[/tex]    [tex][\because \sqrt{ab}=\sqrt{a}\sqrt{b}][/tex]

[tex]\sqrt{-49}=7\times i[/tex]    [tex][\because \sqrt{-1}=i][/tex]

[tex]\sqrt{-49}=7i[/tex]

Therefore, the required expression is 7i.

Answer:

C. AAS

Step-by-step explanation:

Since we are given two angles and one side, that limits our options to B or C. It can't be B, because ASA is only when the side given is in between the two angles, so it must be C.

Answer:

C; x = 900

Step-by-step explanation:

1. Write out the problem: x/15 = 60

2. Multiply each side by 15 to solve for x. This is because of inverse operations, so if you divide x by 15 you have to multiply 15 to both sides. THis way the 15 cancels out in 15(x/15).

3. Equation then becomes this: x = 15*60

4. Answer: 900

5. Substitute to see if you were right. Ask yourself: Does 900 divided by 15 equal 60. If it does, then you are correct.

Answer:

Option E is correct.

- Treatments: how the peppermint oil is dispersed

- Experimental unit: mice

- Response variable: number of mice in the dwellings

Step-by-step explanation:

The treatments in this type of statistical experiment refers to the part of the experiment that is tweaked, controlled or varied in the cases being studied. In this experiment, the method of essential oil dispersal is what is varied in the two experimental cases of this study.

Experimental Unit refers to the subject matters, who are participants in the experiment. They are the ones that the effect of the treatments is tested upon.

For this study, the experimental units are the mice subjected to either of the two methods of peppermint oil dispersal.

The response variable is how the experimental units (participants) respond to the treatments (experimental tweaks). Or how the tweaks manifest observable results in the participants of the study. For this study, the effect of the tweaks in the mice is shown in the number of mice that remain in each dwelling (where the two methods of peppermint oil dispersal have been implemented). Hence, the response variable is the number of mice in each dwelling.

Answer:

It honestly does not matter, but I'd choose the ring because I feel like it is more pleasant to look at.  

Step-by-step explanation:

We need to find the area of both shapes to compare:

3/4 of a circle:

A = 6^2pi

= 36pi

36pi(0.75) = 27pi

Ring:

A = 36pi

A2 = 3^2pi = 9pi

36pi-9pi = 27pi

As you can see, the two areas are the same.

Answer:

$118

Step-by-step explanation:

The amount Jordan will have on 1st of the February is $118

The slope or gradient of a line is a number that describes both the direction and the steepness of the line.

Given that, On February 2nd, Jordan is going on a class trip to Washington, D.C. He is saving his weekly allowance to use as spending money while on the trip. Each week, Jordan's parents give him the $8 he earned for the week,

The saving are

In 1st week = $86

In 2nd week = $94

Therefore, we can consider the coordinates as (1, 86) or (2, 94)

We know that, standard equation of a line = y = mx+c

Where, m is the slope,

We have here slope = 8

Finding for c, put x = 1 and y = 86

c = 78

Now finding the amount for 5 weeks, that means x = 5

y = 5x8+78

y = 118

Hence, The amount Jordan will have on 1st of the February is $118

Answer:

The answer is C.

Step-by-step explanation:

I took the test and got it right! Besides that, here's an explanation:

Blinding is when either the subjects (single-blind) or the subjects and researchers (double-blind) do not know what treatment they are recieving. In this case, the birds know what color treat they are getting, and the researchers do as well. Therefore, there is no blinding being done in this experiment.

If there was, the researchers and the birds wouldn't know the color of the treat, or ONLY the birds wouldn't know the color of the treat. Because this experiment is dependent on the color that the birds see, blinding would kind of contradict the whole point of the experiment.

As by, the blinding demonstrated in the experiment is not there, because the hamsters know whether they are eating a red treat or a blue treat.

As the research is defined as, in accordance with suitable epistemologies set by specific occupational group fields and academic discipline. As documentation of critical collection; and analysis and interpretation of that data/aggregation.

The birds know what color happening they are getting on, and the research worker do as well. Therefore, there is no blinding being done in this experiment. As binding is considered as, the subjects (single-blind) or the subjects and researchers (double-blind)

Therefore, The right option (C) is correct.

Answer:

The answer is 0.

Step-by-step explanation:

Let's call the answer a.

We want to find a(2004)

That's an even term. We look at the even terms:

2   2002

 4   2000

6   1998

8   1996

10   1994

12   1992

We see that the pattern for the even terms is  

"if you add n and a(n), the sum is always 2004."

That is n + a(n) = 2004, or,

           a(n) = 2004-n when n is even

So when n = 2004, a(2004) = 2004-2004 = 0

Step-by-step explanation:

We are told in the question that

If one quart of paint is exactly enough for two coats of paint on a 9-foot by 10-foot wall

9 foot by 10 foot wall = an area of 9 × 10 = 90ft² × 2 coats of paint = 1 quart of paint

We are to find how many quarts of paint are needed

how many quarts of paint are needed to apply one coat of paint to a 10-foot by 12-foot wall .

10 × 12 = 120ft² × 1 coat of paint = x quart

Mathematically, if

One quart of paint = 90ft² × 2

x quart of paint = 120ft² × 1

Cross multiply

90ft²× 2 × x = 120ft²

x = 120/180

x = 2/3 quart of paint

Answer:

13, 15, 17

Step-by-step explanation:

Each digit must be odd, and to get consecutive odd integers, you must add using the multiple of 2:

Let the least number be "x". Set the equation:

(x) + (x + 2) + (x + 4) = 45

Isolate the variable, x. First, combine like terms:

(x + x + x) + (2 + 4) = 45

(3x) + 6 = 45

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract 6 from both sides:

3x + 6 (-6) = 45 (-6)

3x = 45 - 6

3x = 39

Divide 3 from both sides:

(3x)/3 = (39)/3

x = 39/3

x = 13

Your first number (x) is 13. Solve for the other 2 numbers:

(x) = 13

(x + 2) = 13 + 2 = 15

(x + 4) = 13 + 4 = 17

13, 15, 17 are your numbers:

Check:

13 + 15 + 17 = (13 + 15) + 17 = 28 + 17 = 45

Answer:

Part 1: Already solved.

Part 2: 1 quesadilla.

Step-by-step explanation:

Part 1: The data points given are 0, 0, 1/4, 1/2, 1/2, 1, 1, 1, 5/4, 2, and 2.

The data are already sorted from least to greatest.

Part 2: To get the interquartile range, we must know the first and third quartiles. To find those, we need to know the median of the data.

There are 11 data points, so we can cross out 5 numbers on the left and cross out 5 numbers on the right. That leaves a median of 1.

Since we know the median is 1, we can find the first quartile by finding the median of the following numbers: 0, 0, 1/4, 1/2, 1/2 (any number less than 1). There are five numbers, so cross out two numbers from the left and cross out two numbers from the right. We are left with a first quartile of 1/4.

Now that we have the first quartile, we need to find the third quartile. Since the median was actually the first "1" in the data set, the third quartile will be the median of the numbers to the right of that "1": 1, 1, 5/4, 2, 2. Cross out the leftmost two numbers, and cross out the rightmost two numbers. We are left with a third quartile of 5/4.

Now that we have both the third and first quartiles, we can find the interquartile range! The IQR is calculated by finding the third quartile minus the first quartile. 5/4 - 1/4 = 4/4 = 1.

So, your interquartile range is 1 quesadilla.

Answer:

Daylilies cost $11 and shrubs cost $11

Step-by-step explanation:

Let's call the cost of daylilies as x and the cost of shrubs as y. We can write:

9x + 4y = 143 -- Equation 1

14x + 4y = 198 -- Equation 2

5x = 55 -- Subtract Equation 1 from Equation 2

x = 11 -- Divide by 5

9 * 11 + 4y = 143 -- Substitute x = 11 into Equation 1

4y = 44 -- Subtract 99

y = 11 -- Divide by 4

Answer:

75°

Step-by-step explanation:

Since the 2 angles are supplementary and TC is a perpendicular bisector, we know that m∠ATC is 90°

All we need to do is simply subtract 15° from 90° to find m∠ATB:

90 - 15 = 75°

Answer:

Solution,

Let m<ATB be X

[tex]x + 15 + 90 = 180[/tex]

(sum of angle in straight line)

[tex]x + 105 = 180[/tex]

subtract 105 on both sides

[tex]x + 105 - 105 = 180 - 105 \\ x = 180 - 105 \\ x = 75[/tex]

Hope this helps ...

Good luck on your assignment..

Start with the given:

Circle -3, square -6, and square 12.

Start with solving the circle that connects square -6 and square -12.

Since the two circles the surround the square are to be multiplied, divide the square value by one of the circle value.

In this case,

-6 ÷ -3 = 2

So now you have circle 2 and square 12. To solve the other square on the right, do the same technique done in the first part.

12 ÷ 2 = 6

Now multiply 6 and -3 to make the product in the square position.

6 × -3 = -18

So the answers:

Left Circle = 2

Right Circle = 6

Right Square = -18

Answer:

See below

Step-by-step explanation:

It would be like:

=> -3 * 2 = -6
