Answer:

\(792\ \text{pounds}\)

Step-by-step explanation:

\(x_1=70\) cubic feet of fertilizer is used in \(y_1=770\) pounds of strawberries

\(x_2=90\) cubic feet of fertilizer is used in \(y_2=990\) pounds of strawberries

\(x=72\) cubic feet of fertilizer is used

Linear interpolation is applied

\(y=y_1+\dfrac{(x-x_1)(y_2-y_1)}{x_2-x_1}\\\Rightarrow y=770+\dfrac{(72-70)(990-770)}{90-70}\\\Rightarrow y=792\ \text{pounds}\)

72 cubic feet of fertilizer will yield \(792\ \text{pounds}\) of strawberries.

The time take to fill the pool will be 494 hours.

Inlet pipe fills in  38 hours = 1 pool

Inlet pipe fills in 1 hours = 1/38

Drain pipe empty in 39 hours = 1 pool

Drain pipe empty in 1 hour = 1/39

If both pipes are opened together then in pool fills in 1 hour =  1/38 - 1/39

= 1/1482

Therefore, 1/1482 fills in 1 hour.

. Therefore, 1/3 will be:

= 1/3 × 1482

Step-by-step explanation:

\(-\frac{1}{6}b = 3\)

first get rid of the fraction by multiplying both sides by 6

\(-\frac{1}{6} b * 6 = 3 * 6\\-b = 18\)

multiply both sides by -1 to find out what b is

Answer:

(10, 5π/3)

Step-by-step explanation:

To convert rectangular coordinates (5, -5√3) to polar form, we can use the following formulas:

r = √(x^2 + y^2)

θ = arctan(y/x)

Substituting the given values, we get:

r = √(5^2 + (-5√3)^2) = √(25 + 75) = √100 = 10

θ = arctan((-5√3)/5) = arctan(-√3) = -π/3

Note that the value of θ is in the fourth quadrant, which corresponds to a negative angle. However, we need to express the angle θ in the range 0 ≤ θ < 2π. To do this, we can add 2π to the angle if it is negative:

θ = -π/3 + 2π = (5π/3)

Therefore, the rectangular coordinates (5, -5√3) in polar form are (10, 5π/3).

6 ft = 6 ft

Since 6ft is equal to 6ft...

If piece of cake has area of 100 in² and sweeps angle of 50°, then the radius of the cake is 15.13 inches.

The area of the piece of cake is given as 100 square inches and

The piece of cake sweeps out an angle of 50 degrees, we have to find the radius of the cake;

We know that "Area" of a sector of a circle is given as : A = (θ/360)πr²,

where A = area of the sector, θ is = angle swept by sector, and r is radius of circle,

We know that area of "piece-of-cake" is = 100 square inches and

The "angle-swept' by the piece is = 50 degrees.

Substituting the values in area of sector formula,

We get,

⇒ 100 = (50/360)πr²,

⇒ r² = (100 × 360)/(50π)

⇒ r ≈ 15.13,

Therefore, the radius of the cake is approximately 15.13 inches.

a. The researcher should expect each person to get 17 guesses correct under the null hypothesis that the person is guessing.

b. Person A has a smaller p-value because the person's number of successes is further to the hypothesized number of successes.

At the null hypothesis, it is tested if the person is guessing, that is, if the proportion is of 0.5, hence:

\(H_0: p = 0.5\)

At the alternative hypothesis, it is tested if there is enough evidence to conclude that the person is not guessing, that is, if the proportion is different than 0.5, hence:

\(H_0: p \neq 0.5\)

Considering the tested proportion of 0.5, the expected number of correct guesses on the 34 trials is of:

0.5 x 34 = 17 correct guesses.

The test statistic is given by the equation presented as follows:

\(z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}\)

In which:

The parameters that are the same for each person are given as follows:

\(p = 0.5, n = 34\)

The sample proportions are given as follows:

Then the test statistics are given as follows:

Person A is farther from the mean due to the higher test statistical, hence it has a smaller p-value.

Therefore , the solution of the given problem of variable comes out to be quantities (x) of both bracelets and necklaces (y).

A quality who can be assessed and expression assigned different values is called a variable. Variables include things like height, age, wages, province of birth, scholastic standing, and type of housing.

Here,

Assume that y is the number of necklaces made, and x is the number of bracelets produced.

Next, we can formulate the formulae in the following system:

=> 7x + 24y = 172 (the total amount of gold used was 172 grams)

=> y = x + 2 (there were 2 more necklaces made than bracelets)

The total quantity of gold used is shown in the first equation as the sum of the gold used in bracelets

=> (7x) and the gold used in necklaces (x). (24y).

Since there are y necklaces and x bracelets, we can write

=>  y = x + 2 to represent the amount of necklaces.

a set of formulae that can be used to calculate the production quantities (x) of both bracelets and necklaces (y).

Given statement solution is :- It  would cost $680 to install tile in the dining room and $315 to install carpet in the bedroom.

To find the cost of installing tile in the dining room and carpet in the bedroom, we need to calculate the areas of both rooms first.

Given:

Every 2 centimeters on the floor plan represents 1 meter of the house.

Dining Room:

On the floor plan, the dining room is 8 cm by 10 cm.

Converting this to meters, the dimensions of the dining room are 8 cm / 2 = 4 meters by 10 cm / 2 = 5 meters.

The area of the dining room is 4 meters * 5 meters = 20 square meters.

Bedroom:

On the floor plan, the bedroom is 6 cm by 10 cm.

Converting this to meters, the dimensions of the bedroom are 6 cm / 2 = 3 meters by 10 cm / 2 = 5 meters.

The area of the bedroom is 3 meters * 5 meters = 15 square meters.

Now, let's calculate the costs.

Cost of Tile:

The cost of installing tile is $34 per square meter.

The area of the dining room is 20 square meters.

Therefore, the cost of installing tile in the dining room is 20 square meters * $34/square meter = $680.

Cost of Carpet:

The cost of installing carpet is $21 per square meter.

The area of the bedroom is 15 square meters.

Therefore, the cost of installing carpet in the bedroom is 15 square meters * $21/square meter = $315.

Therefore, it would cost $680 to install tile in the dining room and $315 to install carpet in the bedroom.

ANSWER:

They have $1,100 altogether.

EXPLANATION:

- Originally, Mike had $500, while Joel had $600. That adds up to $1,100, and it makes Joel have $100 more than Mike.

- Half of Joel’s $600 is $300, which he gave to Mike. That makes Joel now have $300 himself.

- Adding $300 to Mike’s $500 is $800, which means Mike now has $800.

- $800 (Mike’s new amount) minus $300 (Joel’s new amount) is $500, which works because Mike now has $500 more than Joel.

-$300 + $800 is, of course, still $1,100.
