Can You Explain To Me How To Do These Multiplications Please?

Answers

Answer 1
3•2•1 = 6 - if you break it down it could be done in any way:
(3•2)= 6•1= 6
(2•1)= 2•3= 6
(1•3) = 3•2 = 6

2•3•5 = 30 - same thing as before
(2•3) = 6•5 = 30
(3•5) = 15•2 = 30
(2•5) = 10•3 = 30

4•2•7 = 56 -
(4•2) = 8•7 = 56
(7•4) = 28•2 = 56
(7•2) = 14•4 = 56

3•3•2 = 18 -
(3•3) = 9•2 = 18
(3•2) = 6•3 = 18

Typically you would go from left to right, but any way gets you to the same place. You just multiply the first two numbers then multiply the product of the final value

Rob paid $50.15 for two pairs of jeans, which include a 15% discount.
What was the price of one pair of jeans before the discount was added?

Answers

Answer:

$29.50

Step-by-step explanation:

The price that Rob paid includes a 15% discount.  This means that Rob paid 85% of the original price.

100% - 15% = 85%

Divide the price Rob paid by the percentage the price is of the total.

85% = 0.85

50.15/0.85 = 59

Now, divide the total price by 2 so that you can find the price of one pair of jeans.

59/2 = 29.50

The price of one pair of jeans is $29.50

HL  (Hypotenuse-Leg)

x = 13

Step-by-step explanation:

hypotenuse GJ is shared by both triangles.

∠H and ∠K are right angles so they are right triangles.

leg HG = leg KG

so HL theorem

x + 5 = 8

x = 13

RHS Theorem

(Right angle, hypotenuse and side theorem)

By this theorem GK = GH ,

=> x + 5 = 8

Determine which equation has the same solutions as the given equation.

B.
(x − 5)2 = 36
C.
(x − 5)2 = 21
D.
(x − 10)2 = 21

Answers

I just want to mention that the question is wrongly written!

it's meant to be  x² − 10x − 11 = 0 and not x2 − 10x − 11 = 0

and so the other equations!

Answer:

The answer is B: (x − 5)² = 36

Step-by-step explanation:

by solving the equations using the quadratic formula we found:

the solutions for x² − 10x − 11 = 0 | x = 11, -1

the solutions for A | x = 16, 4

the solutions for B | x = 11, -1

the solutions for C | x = [tex]\sqrt{21} +5[/tex], [tex]-\sqrt{21}+5[/tex]

the solutions for D | x = [tex]\sqrt{21}+10, -\sqrt{21}+10[/tex]

the given equation: x² − 10x − 11 = 0 and the equation B: (x − 5)² = 36 have the same solutions

Therfore B is the correct answer

n(n - 1)(n + 1) + 6n = n^3 + 5n
n(n^2 - 1) + 6n = n^3 + 5n
n^3 - n + 6n = n^3 + 5n
n^3 + 5n = n^3 + 5n (proven)

Hello the reference related to your question is missing attached below is the reference

answer : p ( x - y ≥ 1 ) = 0.0019

Step-by-step explanation:

Assuming 'X' and 'Y' are independent random samples

X : mean value = [tex]U_{1}[/tex] , variance = 0.4 /10 = 0.04

Y : mean value = [tex]U_{2}[/tex] , variance = 0.8/10 = 0.08

since the values are independent

V [ X - Y ] = V [ X ] + V [Y ] = 0.04 + 0.08 = 0.12

Determine the probability that the sample mean for species A exceeds the sample mean for species B by at least 1 unit

P ( x - y ≥ 1 ) = 0.0019

On a coordinate plane, 4 points are plotted. The points are (0, 375), (1, 75), (2, 15), (3, 3).

Answers

Answer: On a coordinate plane, 4 points are plotted. The points are (1, 375), (2, 225), (3, 135), (4, 81).

Step-by-step explanation:

We have the relation:

f(x + 1) = (3/5)*f(x)

such that the first term is 375

Then:

f(1) = 375.

Using the above relation, we have that:

f(1 + 1) = f(2) = (3/5)*f(1) = (3/5)*375 = 225

Then we have the pair (2, 225)

The next term is:

f(2 + 1) = f(3) = (3/5)*f(2) = (3/5)*225 = 135

Then we have the pair (3, 135)

the next term is:

f(3 + 1) = f(4) = (3/5)*f(3) = (3/5)*135 = 81

Then we have the pair (3, 81)

Then the correct option is the first one; On a coordinate plane, 4 points are plotted. The points are (1, 375), (2, 225), (3, 135), (4, 81).

What is Histogram?

A histogram is a graphical depiction of continuous or discrete data. In a histogram, the frequency is represented by the area of a bar. Frequency density, which is proportional to frequency, is plotted on the y-axis, and intervals representing the range of values are plotted on the x-axis.

From the Histogram we have

For 0 -30 minutes - 5 users wait

31- 60 minutes- 4 users wait

61- 90 minutes- 9 users wait

91- 120 minutes- 2 users wait

120- 150 - 4 users wait

So, the number of users waited more than a hour but not more than 2 hours

= 9 + 2

= 11 users
