Answer:
m<1 = 60°
m<2 = 30°
m<3 = 90°
Step-by-step explanation:
Recall some properties of Rectangle. Thus:
The four angles of a rectangle are right angles = 90° each.
Opposite sides of a rectangle are also parallel to each other.
With the knowledge of these, we can solve for angles 1, 2, and 3.
Thus:
m<1 = 60° (alternate interior angles are congruent)
m<2 + m<1 = 90° (complementary angles)
m<2 + 60° = 90° (substitution)
m<2 = 30° (substraction property of equality)
m<3 = 90° (angle of a rectangle)

Worldwide, the proportion of babies who are boys is about 0.51 . Let the random variable X represent the number of boys in five children. Find the mean and standard deviation of this random variable.
Answers
Answer:
mean = 2.55
Standard deviation = 1.118
Step-by-step explanation:
Probability of babies who are boys
P = 0.51
Then we have q = 1-p
= 1-0.51
= 0.49
We have n = 5
We calculate the mean as:
np
= 0.51x5
= 2.55
Therefore mean = 2.55
The standard deviation
= √variance
= √npq
= √0.51x5x0.49
=√1.2495
= 1.118

cross multiply
f k = 2D
divide both sides by f

Gasoline costs 1.05 euro per liter in France. What is the price in dollars per gallon?
Answers
The price in dollars per gallon is 4.02 dollars per gallons.
How to find the price of gasoline in dollars per gallon?Gasoline costs 1.05 euro per litre in France.
The first thing to do is to determine the equivalent amount of the same litre in dollar while in France.
Then, equate it the quantity of litres to gallons.
Hence,
1 euro = 1.01 dollars
1.05 euro = ?
cross multiply
price = 1.05 × 1.01
price = 1.0605 dollars
1 litres = 0.264172 gallons
Therefore,
cost = 1.0605 / 0.264172
cost = 4.01552442257 dollars per gallons
cost = 4.02 dollars per gallons

What is the value of x in the equation? 6(x +1) -5x = 8 + 2(x - 1) *
Answers
Answer:
x = 0
Step-by-step explanation:
6 ( x + 1 ) - 5x = 8 + 2 ( x - 1 )
6x + 6 - 5x = 8 + 2x - 2
-x = 0
x = 0
Answer:
x = 0
Step-by-step explanation:
First distribute both sides to simplify the equation
6(x +1) -5x = 8 + 2(x - 1) =
6x + 6 - 5x = 8 + 2x - 2
Combine like terms
x + 6 = 6 + 2x
Subtract x from both sides
6 = 6 + x
Subtract 6 from both sides

First we convert into slope-intercept form | y = mx + b
[tex]-3y=-3-x[/tex]
Move x to another side and subtract. (Whenever you move to another side, the sign/operator will be opposite. From plus to minus and from multiply to divide.)
Then move -3 to divide (-3-x)
[tex]y=\frac{-3-x}{-3}[/tex]
Separate - [tex]y=\frac{-3}{-3}-\frac{x}{-3}[/tex]
| Negative dividing Negative equal positive |
[tex]y=\frac{3}{3}-(-\frac{x}{3})[/tex] | When the denominator is negative, we can pull out from the denominator and convert into the middle of fraction. |
| Negative multiplying Negative equal positive |
[tex]y=1+\frac{x}{3}[/tex]
This is not fully slope-intercept form yet. We swap the position of 1 and x/3
[tex]y=\frac{x}{3}+1[/tex]
There we go. The slope-intercept form.
Now our job is to find the x-intercept and y-intercept. First, know what m and b represents in the equation y = mx + b first.
From y = mx + b | m represents slope | b represents the y-intercept. |
Our equation is [tex]y=\frac{x}{3}+1[/tex]
Our m or slope is 1/3 and our y-intercept is 1. So we don't need to find the y-intercept because we've already found it.
Now move to finding x-intercept.
Substitute y as we get -
[tex]0=\frac{x}{3}+1[/tex]
Now whenever there is a denominator, multiply the whole equation by the denominator itself. As our denominator in this equation is 3, so we multiply all whole equation by 3.
[tex]0(3)=\frac{x}{3}(3)+1(3)\\0=x+3 \\x=-3[/tex]
Our x-intercept is x = -3 and y-intercept is y = 1.
Check the graph out. Our answers can be only A and B considering the slope is positive. C and D choices have negative slope (m < 0).
However, the value of slope also affects the graph. If the slope has a lot of value, then the graph will head to y-axis.
But if the slope has a little value then the graph will head to x-axis instead.
After all, when converting to the slope-intercept form. We don't need to find the x-intercept right away, just one glance at the graph along with the equation and we are able to answer it.
Thus, the answer is B choice.
I know it is a long, boring explanation. But providing a quality answer is what I'm trying to do. I may not be able to explain that good or whatever.

For the experiment of rolling an ordinary pair of dice, find the probability that the sum will be less than 3 or greater than 5.
Answers
According to the given statement the probability that the sum will be less than 3 or greater than 5 = 27/36.
What is Probability?Probability is simply the likelihood of something occurring. When we are uncertain about the result of an event, we might discuss the probabilities of several outcomes—how likely they are. Statistics is the study of occurrences guided by probability.
According to the given information:When two dice are rolled, the total number of possible outcomes is 36.
sum possibilities probability(favorable/ total outcomes of the event)
2 (1,1) 1/36
3 (1,2) , (2,1) 2/36
4 (2,2), (3,1) , (1,3) 3/36
5 (4,1), (1,4),(2,3),(3,2) 4/36
6 (1,5),(5,1),(2,4),(4,2),(3,3) 5/36
7 (2,5),(5,2)(1,6),(6,1),(3,4),(4,3) 6/36
8 (2,6),(6,2), (5,3),(3,5),(4,4) 5/36
9 (3,6),(6,3),(5,4),(4,5) 4/36
10 (5,5),(4,6),(6,4) 3/36
11 (6,5),(5,6) 2/36
12 (6,6) 1/36
probability that the sum will be less than 3 or greater than 5 = probability for the sum to be 2 + probability for the sum to be 6 + probability for the sum to be 7 + probability for the sum to be 8 + probability for the sum to be 9 + probability for the sum to be 10 + probability for the sum to be 11 + probability for the sum to be 12.
= (1/36) + (5/36) + (6/36) + (5/36) + (4/36) + (3/36) + (2/36) + (1/36)
= (1 + 5 + 6 + 5 + 4 + 3 + 2 + 1)/36

According to the given statement the probability that the sum will be less than 3 or greater than 5 = 27/36.
