Put ( ) around input only.

Insert (-1) for m.

Step-by-step explanation:

You only put parenthesis around just and only the input. So you are replacing m with (-1) and leaving everything else just the same.

m² - m³ - m⁴

(-1)² - (-1)³ - (-1)⁴

Answer:

Step-by-step explanation:

If a number is squared and then divided by 15, the resulting expression can be written as (x^2)/15, where x is the number. For example, if the number is 5, then the expression can be written as (5^2)/15 = 25/15. In general, the value of the expression (x^2)/15 will be the square of the number x divided by 15.

Step-by-step explanation:

At least 9 means more than 9 and includes 9

x ≥ 9     and    [9,  +∞)

At most 9 means numbers less than 9

x≤9       and  (-∞, 9]

more than 9 means bigger than 9 but not including 9

x > 9     and    (9,  +∞)

fewer than 9 means less than 9 but not including 9

x<9       and  (-∞, 9)

strictly between 7 and 9   means between 7 and 9 but not including

7<x<9      and    (7,9)       (This is the only one I'm unsure of.  Strictly, not sure if it includes or doesn't include, usually it just says include or doesn't include)

between 7 and 7 inclusive.   means it's just =7  There's no boundaries

x=7

no more than 7 means less than 7 and includes 7

x ≤ 7   and   (-∞, 7]

The value of y from the give expression is 1

Give the following expression

\(\frac{3y^{-4}}{5} = \frac{3}{5y^{-4}}\)

Cross multiply the given expression

\(3y^{-4}\times 5y^{-4}= 5 \times 3\\15y^{-8}=15\\\)

Divide both sides by 15

\(y^{-8}=1\\\frac{1}{y^8} =1\\y^8=1\\y=1\)

A) Let X be the amount of time it takes Capt. Rigg to land a plane from announcement to touch down. We know that X has a uniform distribution from 0 to 25 minutes. The probability that it takes at least 5 minutes to land the plane is equal to the probability that X is greater than or equal to 5:

P(X ≥ 5) = (25-5)/(25-0) = 20/25 = 0.8

So the probability that, for a randomly selected flight, it takes Capt. Rigg at least 5 minutes to land the plane after the announcement is 0.8.

b) Since X has a continuous uniform distribution, the probability that it takes exactly 15 minutes to land a plane is 0.

It is false that the probability of an individual from this population will have a weight greater than 72 pounds is 0.31 instead it is 0.70

According to the question,

Weight of population follows normal distribution

Mean of population : u = 75 pounds

Population Standard deviation : σ = 5.9 pounds

We have to Check if the probability an individual from this population will have a weight greater than 72 pounds is 0.31

Probability that weight is greater than 72 = P( x > 72)

Subtracting by 75 both sides and then dividing by 5.9

=> P( x - 75 / 5.9 > 72 - 75 / 5.9)

Using Z-statistics,

=> P( z > -3/5.9)

=> P( z > -0.508)

=> 1 - P(z < -0.50)

Using Probability distribution table for z,

=> 1 -  0.305

=> 0.70

Which is not equal to 0.31

Hence, It is false that Probability that weight is greater than 72 is 0.31

The system of equations whose solution is (-12, 10) is the third one:

5x + 5y = -10

x - y = -22

Here we have multiple systems of equations, and we want to see which one has a solution with x = -12 and y = 10.

To check that, we just need to evaluate both equations in these values and check if both are true.

Particularly, if we look at the third system:

5x + 5y = -10

x - y = -22

Evaluating both of these we will get:

5*-12 + 5*10 = -10

-60 + 50 = -10

-10 = -10

x - y = -22

-12 - 10 = -22

-22 = -22

So both equations are true when evaluated in x = -12 and y = 10, so that is the correct option.

The graph of the rational equation is solved and f ( x ) = 1/ ( x + 2 ) ( x - 5 )

Given data ,

Let the function be represented as f ( x )

Now , the value of f ( x ) is

f ( x ) = 1/ ( x + 2 ) ( x - 5 )

The function will have increasingly large values as the denominator approaches zero. When x -2, the denominator is positive and the function tends to the upside. When x -2 x 5, the function is negative. When x 5, the function becomes positive once more.

Hence , the rational function is f ( x ) = 1/ ( x + 2 ) ( x - 5 )

Step-by-step explanation:    Finding the distance between any two integers is obtained by;

Taking the absolute value of the difference between the two integer values.

For instance :

Point A = - 10

Point B = 5

The distance between the two integer points is :

Difference = Point A - Point B = - 10 - 5 = - 15

Absolute value = |-15| = 15

Therefore, This procedure works for any pair of integer distances.

Answer:Find the difference between two integers by adding the additive inverse. The distance is the absolute value of the difference. Check the distance by plotting the original two integers on a number line and counting the units between them.

6.6 °C

Step-by-step explanation:

Alabama temperature in Celsius:

F= 1.8C + 32

Put F = 112 in the above equation

112 = 1.8C + 32

112 - 32 = 1.8C

80 = 1.8C

80/1.8 =C

C = 44.4°C

Difference = 44.4 - 37.8 = 6.6 °C

The following form has two parallel sides, and, in accordance with the provided assertion, its area is 21 cm².

Area is the entire amount of space occupied by a flattened (2-D) surface or form of an item. The area of a planar figure is the space that its perimeter encloses. The quantity of unit rectangles that completely encircle a closed figure's surface is its area. Square units such as cm² and m² are used to measure area.

The ratio will also be 1/2 * (bases 1 + base 2) * length since it is a trapezium.

So, 1/2 * ( 9+5) * 3

   = 1/2 * 14 * 3

Step-by-step explanation:

She cant buy anything over $15, but she can buy something thats $15 :))

Answer:

Bridget has $5.55.

Step-by-step explanation:

First let's find how much money Bridget needs to buy 5 vases. To do this, multiply the cost per vase by the amount of vases she wants to buy:

2 * 5 = 10

It would cost $10 to buy 5 vases.

Bridget needs $4.45 in order to buy 5 vases. So, to find how much money she already has, subtract the amount of money she needs from the total cost of the 5 vases:

10 - 4.45 = 5.55

Bridget has $5.55.

Answer:

$ 5.55

Step-by-step explanation:

Find the price of 5 vases

Cost of 5 vases = 5 * 2 = $ 10

She needs $4.45 to buy 5 vases. If we subtract this 4.45 from $10, the result will be the money she has already with her

Money Bridget has = 10 - 4.45

                               = $ 5.55

According to the information, we can infer that Mazibane must pay R3640 into the account on 30 June to have no debt.

To calculate the amount Mazibane must pay on 30 June to have no debt in the account, we need to consider the initial debt, the interest, and the previous payment.

Initial Debt:

Interest Calculation:

Previous Payment:

To determine the remaining debt on 1 June, we subtract the payment from the initial debt:

From 1 June to 30 June, a period of one month, interest is charged on the remaining debt.

To calculate the interest for one month, we use the formula:

where the principal is the remaining debt, the rate is the monthly interest rate (16%/12), and the time is the number of months (1).

To find the total debt on 30 June, we add the remaining debt on 1 June and the interest for one month:

To have no debt on 30 June, Mazibane must pay the total debt amount:

Calculating the interest and summing up the values, we find that Mazibane must pay approximately R3640 into the account on 30 June to have no debt.
