HELP. How much water is needed to fill a water tank that is 15 feet long, 8 feet wide, and 4 feet deep.
Options:

A: 60
B: 32
C: 480
D: 120

Answer:

D

Step-by-step explanation:

So if Arturo's family hires 3 painters for $50 an hour each, how much do they spend?

X= Charge for number of number of hours

Now let's say that each of the painters worked only one hour each.

That would be take a long time to add up so you multiply.

$50 x 3

In other words it's $50 + $50 + $50.

$50 x 3 = $150

Now X stands for the amount of money paid to each artist. In this case, X= $50. So we already figured out X. X is $50. It is a mistake to add the X at the end of the answer because X is already there in a numerical form. So the answer is D, $150.

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

Explanation:

One painter charges $50 an hour. If they work for x hours, then they charge a total of 50x dollars.

For instance, let's say the painter works for x = 7 hours. This means s/he charges 50*x = 50*7 = 350 dollars overall.

That's for one painter. If we involve 3 painters, then the total bill comes to 50x+50x+50x = 150x dollars

We could also say 3*50x = 150x, since 3*(cost of one painter) = total cost for three painters.

This is why choices A and B are the two answers.

Choice C would be the answer if you only hired one painter. But instead, you hired three of them, so we can rule out choice C.

Choice D only works if x = 1 is plugged into 150x to get 150*x = 150*1 = 150. However, you don't want to limit yourself to this x value only. It's better to stick with 150x instead to be more general. That way you can find the cost for say x = 2 hours which is 150*x = 150*2 = 300 dollars. I'll let you try other x values.

Answer:

B. Approximately 0.3159

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution, and the central limit theorem.

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

The mean volume of all gallon containers is 1.00 gallon with a standard deviation equal to 0.10 gallon.

This means that [tex]\mu = 1, \sigma = 0.1[/tex]

Sample of 9:

This means that [tex]n = 9, s = \frac{0.1}{\sqrt{9}}[/tex]

If the sample mean is less than 0.97 gallons, the department will fine the dairy. Based on this information, what is the probability that the dairy will get fined even when its filling process is working correctly?

This is the pvalue of Z when X = 0.97. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{0.97 - 1}{\frac{0.1}{\sqrt{9}}}[/tex]

[tex]Z = -0.9[/tex]

[tex]Z = -0.9[/tex] has a pvalue of 0.1841.

The correct answer is given by option B.

Answer:

Option C

Step-by-step explanation:

Given  

Probability of Mean value less than 0.97  

= Mean value -1/(0.1/sqrt (9))

Substituting the given values, we get -

Probability of Mean value less than 0.97  

= 0.97 -1/(0.1/sqrt (9))

= 0.97-1/(0.1/3)

= 0.1841

Hence, option C is correct

The required equation model for the condition of the number of lightbulbs in p packages is given as n = 24p.

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

Here,
There are 24 lightbulbs in a package. Let n represent the number of lightbulbs in p packages.
So according to the question,
n = 24p

Thus, the required equation model the given equation is given as n = 24p.

Answer:

The measure of angle a is of 140º.

Step-by-step explanation:

Supplementary angles:

If two angles are supplementary, their measures add to 180º.

Angle a and angle b are supplemetary angles.

This means that

<a + <b = 180º.

m angle a = (5x+25) and m angle b = (x+17)

So

[tex]5x + 25 + x + 17 = 180[/tex]

[tex]6x + 42 = 180[/tex]

[tex]6x = 138[/tex]

[tex]x = \frac{138}{6}[/tex]

[tex]x = 23[/tex]

Measure of angle a:

[tex]<a = 5x + 25 = 5(23) + 25 = 140[/tex]

The measure of angle a is of 140º.

Step-by-step explanation:

THE CORRECT ANSWER is 25 Cm³

Explanation:

Let's consider the vertical block first, having height 8cm, length 1 cm, width 2cm.

Hence the volume of that block = l.w.h = 8×2×1 = 16 cm³

Coming to the horizontal block, having height 3cm, width 3cm, & length 1 cm.

Hence the volume of that block will be = 3×3×1 = 9 cm²

The total volume of irregular figure = Volume of vertical block + horizontal block = 16+9 = 25 cm³

Answer:

Length  =  5.3852

Answer:

√29

Step-by-step explanation:

The change in x from one point to the other is 2; that in y is 5.

Use the Pythagorean Theorem to find the length of the hypotenuse (which is the desired distance):

d = √(2² + 5²) = √29

[tex]y = {x}^{2} [/tex]

Substitute the values of x to find y. Example:

[tex]when \: x = - 1 \\ y = { - 1}^{2} \\ y = 1 [/tex]

So do that for the other values of x.

Answer:

For angle of 210°, coterminal angles are; 570° and -150°.

For angle of -120°, coterminal angles are; 240° and -480°

Step-by-step explanation:

Since we are asked to angle find angle that's coterminal, we will add/ subtract 360° from each angle respectively to get that because coterminal angles are defined as those that share the same terminal side. Thus;

For angle of 210°, coterminal angles are;

>> 210° + 360° = 570°

>> 210° - 360° = - 150°

For angle of -120°, coterminal angles are;

>> - 120° + 360° = 240°

>> - 120° - 360° = - 480°
