Answer:

90.3%

Step-by-step explanation:

I think you have a typo. I'm pretty sure you meant mean score. To find the mean, we add up all the values and divide by the number of values. Let's add 92, 89, and 90. That gets us 271. Now, let's divide 271 by 3. That gets us 90.3. That means Jesse's mean score is 90.3%.

Answer:

D. $A\subset \mathbb{R}\times\mathbb{R}.$

Step-by-step explanation:

Consider the set

$A=\left\{(2,3),\ (5,1),\ (-3,-2),\ (0,3)\right\}$

This set consists of four ordered pairs.

The first numbers in these pairs are $2,\ 5,\ -3,\ 0.$ These numbers are integer numbers (not natural, because -3 is negative).

The second numbers in these pairs are $3,\ 1,\ -2,\ 3.$ These numbers are integer numbers too (not natural, because -2 is negative).

Options contain only natural and real sets, so, the first and the second numbers are real numbers and

$A\subset \mathbb{R}\times\mathbb{R}.$

Answer:

Below in bold.

Step-by-step explanation:

I'll solve a few of them to illustrate the method:

a) 5x - (3x - 1) = x - 4

The aim is to get all the 'x' terms to one sides of the '=' and the numbers to the other side:

Distribute the negative over the 3x - 1 in the parentheses:

5x - 3x + 1 = x - 4 ( Note that -* -1 = + 1)

Now subtract 1 from both sides:

5x - 3x + 1 - 1 = x - 4 - 1

5x - 3x = x - 5

Now subtract x from both sides:

5x - 3x - x = x - x - 5.

2x - x = -5

x = -5.

(b) 3/5 x + 1 = 2/5 - 3x

We first get rid of the fractions by multiplying each term by 5:

5 * 3/5 x + 1*5 = 5 * 2/5 - 5*3x

3x + 5 = 2 - 15x

3x + 15x + 5 = 2 - 15x + 15x (adding 15x to both sides)

18x + 5 = 2 Subtract 5 from both sides:

18x + 5 - 5 = 2 - 5

18x = -3

Now we divide both sides by 18:

x = -3/18 = -1/6.

g) 0.3(6 + m) = 0.4(8 - m)

0.3 * 6 + 0.3* m = 0.4*8 + 0.4 * -m ( Distributing the 0.3 and 0.4 over the parentheses)

1.8 + 0.3m = 3.2 - 0.4m ( recall that + * - = -)

1.8 - 1.8 + 0.3m = 3.2 - 1.8 - 0.4m

0.3m = 1.4 - 0.4m

0.3m + 0.4m = 1.4 - 0.4m + 0.4m

0.7m = 1.4

m = 1/4/0.7

m = 2.

I hope this helps.

Consider the first payment against a $200,000 mortgage that last for 25 years. Fixed repayments are made on a monthly basis. The

Delvig [45]

The value of d = $1088.63
fixed monthly payments made = $372

Given that :

Present value ( PV ) $200,000

Period = 25 years

Total period ( n ) = 25 * 12 = 300

also PMT is done monthly

∴ monthly interest rate = ( 716.67 / 200,000 ) * 100 = 0.358% ( r )

i) Next step : Calculate the value of PMT

using the equation below

$PMT = [\frac{PV}{\frac{1-(1+r)^{-n} }{r} } ]$ where : PV = $200,000, r = 0.358% , n = 300

input values into equation

∴ d = PMT = $1088.63

ii) Fixed monthly payments

= d - 716.67

= 1088.63 - 716.67 = $372
