Answer:

A to C is [tex]37.51\ ft[/tex]

Step-by-step explanation:

We are given an angle and the base length. Recall:

[tex]tan(x) = \frac{opposite}{adjacent}[/tex]

Add the values:

[tex]tan(15) = \frac{x}{140}[/tex]

Solve for x:

[tex]tan(15) = \frac{x}{140}\\tan(15) * 140 = x\\37.51 = x[/tex]

Answer:

a: 88.5

b: 91

c: 91, 93

d: 88.5 AKA: the mean value.

Step-by-step explanation:

For answer D: A mean is defined as the mathematical average of the set of two or more data values which makes is perfect for calculating an overall grade by averaging all unit points together.

Answers:

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

Explanation:

Part (a)

To get the mean, first we add up the scores

89+91+94+93+93+67+90+91 = 708

Then we divide over 8 since there are 8 scores total

708/8 = 88.5

The mean is 88.5

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

Part (b)

To get the median, we first need to sort the values from smallest to largest.

That sorted set looks like: {67,89,90,91,91,93,93,94}

Now cross off the first and last values to get this smaller subset: {89,90,91,91,93,93}

Repeat the last set of steps to cross off the first and last items to get {90,91,91,93}

Do this one more time to get {91,91}. The midpoint of these two values is 91, so it's the median of the entire original set.

The median is 91.

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

Part (c)

The mode is {91, 93}

In other words, we have two modes and they are 91 and 93. It's perfectly possible to have more than one mode. The mode is the most frequent item(s). In this case, both 91 and 93 show up exactly twice which is the most of any other value.

As you can see, the mode isn't particularly useful as a single measure of center since we have two values instead of 1.

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

Part (d)

As mentioned in the previous section, the mode isn't useful in this case. So we can rule it out. We can also rule out the mean because the value 67 is far from the group of other values (which is basically like the main cluster). We consider 67 an outlier.

The outlier pulls on the mean to be smaller than it should be. The median is a better measure of center since it's not affected by outliers.

As a real world example, consider home prices. The median price is used because of very expensive multimillion dollar mansions that greatly skew the mean to be larger than it should be.

Answer:

The Answer is C.

Step-by-step explanation:

f(x) = cos x , g(x) = cos(x - π/4)

Equation: f(x) = a * cos (x - h) + k

Since the equation only has h = π/4, it means that it shift right.

Answer:

(a) r = -0.947928522

(b) strong, negative

Step-by-step explanation:

The Product Moment Correlation Coefficient (r) measures the strength of the linear correlation between two variables.

The PMCC is always between +1 and -1.

The closer the value of r is to +1 or -1, the stronger the correlation between the two variables.

Inputting the data from the table into a calculator and using the statistical function:

r = -0.947928522

As the value of r is close to -1, the best description for the correlation would be strong, negative

Answer:

860

Step-by-step explanation:

Just add 840 and 20 together   lol

[tex]\qquad \textit{Amount for Exponential Decay} \\\\ A=P(1 - r)^t\qquad \begin{cases} A=\textit{current amount}\dotfill &\$12000\\ P=\textit{initial amount}\dotfill &\$30000\\ r=rate\to 25\%\to \frac{25}{100}\dotfill &0.25\\ t=years\\ \end{cases}[/tex]

[tex]12000=30000(1 - 0.25)^{t}\implies \cfrac{12000}{30000}=(1 - 0.25)^{t}\implies \cfrac{2}{5}=0.75^t \\\\\\ \log\left( \cfrac{2}{5} \right)=\log(0.75^t)\implies \log\left( \cfrac{2}{5} \right)=t\log(0.75) \\\\\\ \cfrac{~~\log\left( \frac{2}{5} \right)~~}{\log(0.75)}=t\implies 3\approx t[/tex]

Answer:

The price of a medium pizza with 3 toppings is $15.

Step-by-step explanation:

If "t" represents the number of toppings, you will use the expression "9+2t" and plug in 3 for t (since there are 3 toppings)

So it will look like:

9+2(3)

Then you're gonna use PEMDAS, multiply 2*3

9+6

And then you get an answer of $15

Answer:

h=6

Step-by-step explanation:

To find the volume of a right angle prism-

Find area of cross-section, in this case an isoscles triangle so we know that both of the parallel lines are 3ft

To find the area of the cross-section, do:

3 x 3 = 9

9 ÷ 2 = 4.5 (Area of cross-section)

Since we don't know the length of h, we need do:

27^3 ÷ 4.5 = 6

Therefore 6 is h

Hope I explained it okay:)

Answer:

75

Step-by-step explanation:

because the formula of finding the area of a triangle is base times height divided by 2 so thatshow you get the answer, multiply 10by15 and then divide by 2

Answer:

The answer would be 75 ft ^2

Step-by-step explanation:

Step 1. Do 15x10 (which equals 150)
Step 2. Divide by 2 to get the answer of 75
Step 3. Label to get 75 ft ^2

Step-by-step explanation:

Answer:

45 in 6 hours

Step-by-step explanation:

3 inches in 2 minutes

So every hour, it can do 90 inches (since we multiply 2 times 30, we have to multiply 3 times 30)

So next we need to find out how much it goes in 6 hours, so we take 6 x 90.  That gives us 540.  

Lastly, we take 540 and divide it by 12 (since there are 12 inches in a foot) and that gives us 45 feet in 6 hours.

Answer:

540 feet

Step-by-step explanation:

Convert hours to minutes - 6 * 60 = 360 minutes

3 inches in 2 minutes = 1.5 inches in 1 minute (I did this just to make the next steps easier)

Figure out the number of feet moved in 6 hours - 1.5 * 360 = 540 feet

Answer: 0.06

Step-by-step explanation:

Since we only care about winning the inflatable crayon, it is unimportant whether nothing is won or a small stuffed animal is won, just that the outcome is determined by subtracting all of the possible outcomes given from the probability of winning nothing and the probability of winning a stuffed animal. Given that the total probability of all outcomes of the event is 1, we can conclude that the probability of winning an inflatable crayon is:

[tex]P(\text{not winning inflatable crayon}) = P(\text{All Outcomes}) - P(\text{winning nothing})[/tex]

[tex]- P(\text{winning a small stuffed animal)}[/tex]
