Jill records the temperature outside every hour for 4 hours. She finds that the temperature dropped by the same amount each hour. After 4 hours, she finds that the temperature dropped a total of 20∘F. She writes this number sentence.
(−20)÷4=−5
What does the number sentence mean?
1. The total drop in temperature, −20∘F, divided by 4 hours equals −5∘F per hour. The temperature dropped 5∘F each hour.
2. The total number of drops, 20, divided by 4 hours equals 5 times per hour. The temperature dropped 5 times per hour.
3. The total drop in temperature, −20∘F, divided by 4∘F in the first hour, equals −5 drops. The temperature dropped 5 times.
4. The total number of hours, 20, divided by 4∘F equals 5 hours. The temperature dropped once every 5 hours.

The correct option is a)58500.

The number of different registration number possible when the repetition is not allowed is 58500.

Selections are another name for combinations. Combinations are the selection of items from a given set of items.

Now, according to the given question;

The total number of digits mentioned on the number plate is 4.

The first place is to be filled by letter.

We know that there are total 26 letter. So, there are total 26 possible ways in which the place is filled.

Now, the second place is also to be filled by the letter, but now the letter left are 25. Thus, possible fillings is by 25 letter.

The third position is to be filled by number; there are 10 number (0 - 9) by which the position can be filled.

The fourth position is also to be filled by the number; but now the numbers left are 9.

Thus, the total combination is;

= 26×25×10×9

= 58500

Therefore, there are 58500 possible ways in which the number plate can be formed.

3 full shifts of 3/4 hour and 1 half shift of 3/4 hour

Shift work is an employment strategy intended to utilize or give service during each of the seven days of the week's full 24 hours. The day is often divided into shifts, predetermined times when various groups of workers carry out their tasks.

Total work hours = 2.625 hours

Each shift = 0.75 hr

Number of shifts = Total work hours / Each shift

                            = 2.625 / 0.75

                            = 3.5

Therefore, He worked three full shifts of three hours each and one half-shift of three hours.

Levi must score 220 in Exam B in order to do equivalently well as he did in Exam A

The given parameters are:

Exam A

Score = 710

Mean = 700

Standard deviation = 25

Exam B

Mean = 200

Standard deviation = 50

The z-score is calculated as

z = (Score - Mean)/Standard deviation

For exam A, we have

z = (710 - 700)/25

z = 0.4

For exam B, we have

z = (Score - 200)/50

Substitute z = 0.4 in z = (Score - 200)/50

0.4 = (Score - 200)/50

This gives

Score - 200 = 20

Add 200 to both sides

Score = 220

Hence, Levi must score 220 in Exam B in order to do equivalently well as he did in Exam A

The slope of equation  y = -5/6 x + 4 is -5/6 and the slope-intercept form of -5/6x+4 is y = -5/6 x + 4

The slope of a function y = f(x) is given by a formula

slope = y2-y1 / x2- x1

where ( x1 , y1) and (x2, y2) are coordinates of any two points on the line of graph representing y = f(x)

Or we can simply use the slope-intercept form

y = mx+ c

where m is the slope of the given equation and c is the constant

so, in  the given equation y = -5/6 x + 4

slope of the equation is -5/6

Hence, The slope of equation  y = -5/6 x + 4 simply is -5/6 and the slope intercept form of -5/6x+4 is y = -5/6 x + 4

When you know the slope of the line to be investigated and the point given is also the y intercept, you can utilize the slope intercept formula y = mx + b. (0, b). The y value of the y intercept point is represented by b in the formula.

The truth value of the conditional statement is false

How to determine the truth value of the conditional statement?

The conditional statement is given as

“If a number is greater than -500, then the number is greater than 500.”

The above conditional statement is false

This is because not all numbers greater than -500 are greater than 500

for example 450 is greater than -500, but less than 500 that is the number between -500 and 500 will not satisfy the above statement.

The given parameters are

C = (1, 6)

m : n = 3 : 1

So, the coordinate of point E is

E = 1/(m + n) * (mx2 + nx1, my2 + ny1)

So, we have:

E = 1/(3 + 1) * (3 * -3 + 1 * 1, 3 * -4 + 1 * 6)

Angles on a straight line must add up to 180 so angle BCA is 180-132=48

Because the triangle BAC is an isosoles angle BCA and ABC must be the same so 48

We can now use the angle on a straight line rule to figure out angle DBA 180-48=132

We know that triangle DBA is an isosoles trianlge so and x and DAB must be the same and both be x, and we know that angles in a triangle add up to 180 so the equation can be written as:

180=2x+132

The constant percent rate of change is of 4%

Using compound interest, it is found that the constant percent rate of change is of 4%.

The formula for an amount of money invested into compound interest is given by:

[tex]A(t) = A(0)(1+r)^{t}[/tex]

In which:

A(t) is the amount after t years.

A(0) is the initial amount.

r is the constant percent rate of change.

t is the time.

The function is:

[tex]g(x)=300(1.04)^{x}[/tex]

Thus, for the constant percent rate of change:

1+r = 1.04;

r = 0.04;

0.04 × 100% = 4%

The constant percent rate of change is of 4%.

3230 Kilograms of the soil supplement are required for the entire Vineyard.

Some units that need to be recalled are as follows:

1 km = 1000 m

1 km^2 = 1000000 m^2

1 km^2 = 247 acres

1 kg = 1000 g

Let's tackle the problem now:

A vineyard has 145 acres of Chardonnay grapes.

145 acres = [tex]\frac{145}{247}[/tex]× 1 km^2

145 acres = 145/247 km^2

145 acres ~ 0.587 km^2

A particular soil supplement requires 5.50 grams for every square meter of vineyard

1m^2 → 5.50 gram

1 km^2 = 10^6 →5.50 x 10^6 gram

1 km^2 →5.50 x 10^6 x 10^-3 kg

1 km^2 →5.50 x 10^3 kg

145 acres = 145/247 km^2 →145/247 x 5.50 x 10^3 kg

145 acres → 797500/247 kg

145 acres → 3230 kg

It required 797500/247 kg ~ 3230 kg of the soil supplement for the entire Vineyard.
