Find the equation of the plane through the point p=(5,5,4)p=(5,5,4) and parallel to the plane 5x+2y−z=−6.

Contractor A estimated a job would cost $54,000 to complete in 90 days.

Per day charge of Contractor A = $54,000 / 90 = $ 600 / day

Contractor B estimated he could complete the same job for $49,500 in 120 days.

Per day charge of Contractor A = $49,500 / 90 = $ 412.50 / day

Therefore, Contractor A charges $ 600 per day and contractor B charges $412.50 per day.

Hope it helps..!!

Thank You :)

There are 12 ways Jackson can order his hot cocoa by choosing from three flavors, two mug sizes, and the option of adding marshmallows. Option D is correct,

To find the total number of ways Jackson can order his hot cocoa, we need to consider all the possible combinations of choices he has.

1. Flavor: Jackson has 3 options: milk chocolate, dark chocolate, or chocolate mint flavor.

2. Mug Size: Jackson has 2 options: small or large mug.

3. Marshmallows: Jackson has 2 options: with or without marshmallows.

To find the total number of combinations, we multiply the number of options for each choice:

[tex]\[ \text{Total combinations} = \text{Number of options for flavor} \times \text{Number of options for mug size} \times \text{Number of options for marshmallows} \]\[ \text{Total combinations} = 3 \times 2 \times 2 \]\[ \text{Total combinations} = 12 \][/tex]

So, there are 12 ways Jackson can order his hot cocoa. Therefore, the correct answer is option D) 12.

On a map of Scotland, drawn to the scale of 1:325,000, 65 KM of real-world distance will be represented by 20 cm on the map.

The question pertains to the scale existing on a map. A map scale enables us to convert the measurements on the map into the corresponding real-world distances. Here, we have a map of Scotland that is drawn to the scale of 1:325,000. This signifies that 1 cm on the map equates to 325,000 cm in reality.

To ascertain how many cm on the map would represent 65 KM, we first need to convert 65 KM into cm. As we know, 1 KM is equal to 100,000 cm. Therefore, 65 KM will be equivalent to 65 * 100,000 = 6,500,000 cm.

Now, we divide the real-world cm (6,500,000 cm) by the scale (325,000), which gives us the cm on the map. Thus, 6,500,000 cm / 325,000 = 20 cm

So, on this map, 65 KM will be denoted by 20 cm.

Solution:

we are given that

You have a large container of olive oil. You have used [tex]22 \frac{1}{2}[/tex] quarts of oil.

Twenty-five percent of the olive oil remains.

we have been asked to find how many quarts of olive oil remain?

Let there were x quarts of olive oil.

It mean , we can write

[tex]x-22 \frac{1}{2}=\frac{1}{4}*x[/tex]

[tex]x-\frac{1}{4}*x=22 \frac{1}{2}[/tex]

[tex] \frac{3x}{4}=22 \frac{1}{2}[/tex]

[tex] 3x=4*22 \frac{1}{2}[/tex]

[tex] x=\frac{4}{3}* \frac{45}{2}[/tex]

[tex] x=30[/tex]

Hence quarts of olive oil remain [tex] =30-\frac{45}{2}=\frac{15}{2}=7\frac{1}{2}[/tex]

Answer:  The required sum is 504.

Step-by-step explanation:  We are given to find the sum of the following arithmetic series using the formula for the sum of an arithmetic series :

[tex]\sum_{i=1}^{18}(2i+9).[/tex]

The given arithmetic series can be written, in expanded form, as follows :

[tex]11+13+15+17+~.~.~.~+43+45.[/tex]

We know that

the sum of first n terms of an arithmetic series with first term a and common difference d is given by

[tex]S=\dfrac{n}{2}\{2a+(n-1)d\}.[/tex]

In the given series, a = 11 and d = 13 - 11 = 15 - 13 = . . . =2.

Therefore, the sum up to 18 terms will be

[tex]S_{18}=\dfrac{18}{2}\{2\times 11+(18-1)\times2\}=9(22+34)=9\times56=504.[/tex]

Thus, the required sum is 504.

The sum of the arithmetic series ∑₁¹⁸(2i + 9) using the arithmetic series formula is 504.

To find what is the sum of the arithmetic series ∑₁¹⁸(2i + 9) below using the formula for the sum of an arithmetic series, we proceed as follows

The formula for the sum of therms of an arithmetic series is given by

Sₙ = n/2(a + Tₙ) where

Now, since we have that arithmetic series, ∑₁¹⁸(2i + 9), the nth terms is U = 2i + 9

Now, the first term is when i = 1.

So, U₁ = a = 2(1) + 9

= 2 + 9

= 11

Also, the last term is when i = 18

So, U₁₈ = T₁₈ = 2(18) + 9

= 36 + 9

= 45

So, the sum of terms Sₙ is when n = 18

S₁₈ = 18/2(11 + 45)

= 9(56)

= 504

The correct answer is  [tex]\frac{9}{8}[/tex] is greater than 2 halves.

To compare 9/8ths and 2 halves, we need to convert them to equivalent fractions with the same denominator, and then compare their numerators.

[tex]\text{Step 1: Convert 2 halves to an equivalent fraction with the denominator of 8}[/tex]

[tex]2\text{ halves} = 2 \times \left(\frac{4}{8}\right) = \frac{8}{8}[/tex]

[tex]\text{Step 2: Compare the numerators of }\frac{9}{8}\text{ and }\frac{8}{8}[/tex]

[tex]\text{Since }9 > 8\text{, therefore, }\frac{9}{8} > \frac{8}{8}[/tex]

Therefore, [tex]\frac{9}{8}[/tex] is greater than 2 halves.

Using z-score formula, the probability that a male's head breadth is less than 6.2 inches, would be approximately 57.9261%.

When you have multiple samples and want to describe the standard deviation of those sample means (the standard error), you would use this z score formula:

[tex]z=\frac{x-\mu}{\sigma}[/tex]

This z-score will tell you how many standard errors there are between the sample mean and the population mean.

We have been given that men have head breadths that are normally distributed with a mean of 6.0 inches and a standard deviation of 1.0 inches. We are asked to find the probability that a man's breadth is less than 6.2 inches.

First of all, we will find z-score corresponding to sample score of 6.2 as:

[tex]z=\frac{x-\mu}{\sigma}[/tex]

where,

z = Z-score,

x = Sample score,

[tex]\mu[/tex] = Mean,

[tex]\sigma[/tex] = Standard deviation.

Upon substituting our given values in z-score formula, we will get:

[tex]z=\frac{6.2-6.0}{1.0}[/tex]

[tex]z=\frac{0.2}{1.0}[/tex]

z = 0.2

Now, we need to find the probability that a z-score is less than 0.2.

Using normal distribution table, we will get:

P(z < 0.2) = 0.57926

0.579261 ≈ 57.9261 %

Therefore, the probability that a male's head breadth is less than 6.2 inches, would be approximately 57.9261%.

Answer:

A,C,D,E

Step-by-step explanation:

An equation is formed of two equal expressions. The correct options are 1, 3, 4, and 5.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given that One student sold 5 small boxes and 13 large boxes for $232. Another student sold 12 small boxes and 7 large boxes for $218. Also, x represents the price of the small boxes and y represents the price of the large boxes. Therefore,

The equation for the first student can be written as,

5x + 13y = 232

The equation for the second student can be written as,

12x + 7y = 218

Now, the multiplication that can be done to eliminate the variables are,

1.) The first equation can be multiplied by –12 and the second equation by 5 to eliminate x.

3.) The first equation can be multiplied by –7 and the second equation by 13 to eliminate y.

4.) The first equation can be multiplied by 7 and the second equation by –13 to eliminate y.

5.) The first equation can be multiplied by 12 and the second equation by –5 to eliminate x.

Hence, the correct options are 1, 3, 4, and 5.
