Step-by-step explanation:

Answer:

1) B. 2) A.

Step-by-step explanation:

For number 1, put 30 into the equation. (3•30-5). When solved, your answer is 85, the same as the top. They are vertical angles which makes the two equal.

For number 2, I tried to draw the triangles on paper and the one that wasn't possible was A. The side 6 would be too long to connect to 4 or 3.

Answer:

Monthly withdraw= $3,124.19

Step-by-step explanation:

Giving the following information:

Present Value (PV)= $550,000

Number of periods (n)= 22*12= 264 months

Interest rate (i)= 0.04/12= 0.0033

To calculate the monthly withdrawal, we need to use the following formula:

Monthly withdraw= (PV*i) / [1 - (1+i)^(-n)]

Monthly withdraw=  (550,000*0.0033) / [1 - (1.0033^-264)]

Monthly withdraw= $3,124.19

Answer:

Hello there! There is a 1/4 chance of getting the same result on both flips, keeping in mind that a coin only has 2 sides.

Step-by-step explanation:

There is a 1/2 chance of getting a result on one flip. So we now have to multiply that by getting the same result on another flip.

1/2 × 1/2 = 1/4

Hope this helps! :)

The probability of obtaining the same result on each coin will be 1/2.

Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences.

Then the probability is given as,

P = (Favorable event) / (Total event)

Ken flips 2 fair coins. The total events are given as,

Total event = 2 x 2

Total event = 4 {TT, HT, TH, HH}

The probability of obtaining the same result on each coin will be given as,

Favorable events = 2 {TT, HH}

P = 2 / 4

P = 1/2

The probability of obtaining the same result on each coin will be 1/2.

Answer:

52.48x ≤ 288.64

x≤5.5, x=5

Step-by-step explanation:

First off, we must find out how much money he has available after buying the bike, reflectors and gloves:

Total spent = (price of bike)+3(price of reflectors)+(price of gloves)

=233.09+3(16.38)+29.13

=311.36

600-311.36=288.64, so he has $288.64 left to spend on outfits.

The cost of x amount of outfits is found by multiplying the amount of outfits, x, by the cost per outfit, 52.48: 52.48x. Since he can only spend up to $288.64, 52.48x must be less than or equal 288.64:

52.48x ≤ 288.64

To solve, divide both sides by 52.48:

x≤5.5

(Since he cant buy half of a product, x's maximum value is 5)

Answer:

30%

Step-by-step explanation:

subtract the post-discount price from the pre-discount price

64.99 - 45.49 = 19.50

divide the answer by the original price

[tex]\frac{19.50}{64.99}[/tex] = 0.30

multiply the answer by 100

0.30 x 100 = 30%

to check:

take the original number and multiply it by the decimal form of the percentgae:

64.99 x 30% (0.30) = 19.50

take the answer and subtract it from the orginal answer

64.99 - 19.50 = 45.49

Answer:

0.7 = 70% probability they'll eat lunch at Carl's Jr. Wednesday.

Step-by-step explanation:

We have that:

Carl's Jr on Monday.

On Tuesday:

40% probability of Carl's Junior.

100 - 40 = 60% probability of Wendy's.

On Wednesday:

If on Tuesday it was on Carl's Junior, 40% probability of Carl's Junior on Wednesday.

In on Tuesday it was on Wendy's, 100 - 10 = 90% probability of Carl's Junior on Wednesday.

What is the probability they'll eat lunch at Carl's Jr. Wednesday?

[tex]p = 0.4*0.4 + 0.6*0.9 = 0.7[/tex]

0.7 = 70% probability they'll eat lunch at Carl's Jr. Wednesday.

Answer:

The equation of the line is:

[tex]y = -\frac{1}{3}x - 2[/tex]

Step-by-step explanation:

Equation of a line:

The equation of a line has the following format:

[tex]y = mx + b[/tex]

In which m is the slope and b is the y-intercept, that is, the value of y when x = 0.

(0,-2)

This means that the y-intercept is -2, that is, [tex]b = -2[/tex]. So

[tex]y = mx - 2[/tex]

Finding the slope:

When we have two points, the slope is given by the change in y divided by the change in x.

We have points  (6,-4) and (0,-2).

Change in y: -2 - (-4) = -2 + 4 = 2

Change in x: 0 - 6 = -6

Slope: [tex]m = \frac{2}{-6} = -\frac{1}{3}[/tex]

So the equation of the line is:

[tex]y = -\frac{1}{3}x - 2[/tex]

Answer:

17 : 31

Step-by-step explanation:

[tex]\frac{34}{62} =\frac{17}{31}[/tex]

Answer:

17:31

Step-by-step explanation:

We can simplify the ratio 34 : 62 by dividing both terms by the greatest common factor (GCF).

The GCF of 34 and 62 is 2.

Divide both terms by 2.

34 ÷ 2 = 17

62 ÷ 2 = 31

Therefore:

34 : 62 = 17 : 31

Step-by-step explanation:

The measure of the diagonal BD is 15 units.

A square is a quadrilateral with four equal sides. There are many objects around us that are in the shape of a square. Each square shape is identified by its equal sides and its interior angles that are equal to 90°.

Given that, the diagonals of square ABCD intersect at point E.

Here, BE = 2x + 1, and AC = 3(6x-4)

Now, AC=BD

BD=2BE

So, 3(6x-4)=2(2x+1)

18x-12=4x+2

18x-4x=2+12

14x=14

x=1

So, BD=3(6x-1)=15

Therefore, the measure of the diagonal BD is 15 units.

Answer:

23

Step-by-step explanation:

4r-10=18

4r=28

4r/4=28/4

r=7

2(7)+9=23

The first part where he mentions "The distribution is skewed right" is correct. The tail on the right hand side is pulled longer than it should be, or longer compared to the left tail. "Right skew" or "skewed right" is the same as "positively skewed". They all mean the same thing.

The portion where Maurice says "This implies that the mean is less than the median" is incorrect. This is where his error is located. The reason for the error is because it should be "The mean is greater than the median" when we have right-skewed data like this.

Here's one example to see why this is the case. Consider the distribution {1,2,3,4,5}. We can see that the median is 3 since it's directly in the center. The mean is also 3 since we add up all the values and divide by 5. Symmetric data has mean = median. Now, we'll replace the '5' with something much larger to get a large outlier. Let's say we have the set {1,2,3,4,55}. The median is still 3. The outlier doesn't pull on the median. However, the mean has changed and it is (1+2+3+4+55)/5 = 65/5 = 13. The mean went from 3 to 13. Therefore, mean > median here. The mean is affected by outliers. Think of it like the outlier is pulling on the mean in a sort of magnetic way. This outlier makes the mean larger than it should be. If the outlier is extreme enough, then it sometimes makes sense to consider the trimmed mean as opposed to the regular arithmetic mean. The trimmed mean is the mean of the main cluster of values ignoring the outlier(s).

-----------------------

To recap:

If we have right skewed data, then mean > median

As you can probably guess, if we had left-skewed data, then mean < median. In symmetric data, mean = median.

Answer:

a. 14/15

b. 1/12

Step-by-step explanation:

a) 1/3 + 3/5

so find the lowest common multiple for the denominators which is 15

then say 15 ÷ 3 = 5

then 15 ÷ 4 = 3 (you are dividing by the denominators)

say 5 × 1 (multiple by the numerators now)

= 5

= 5/15

now say 3 × 3 = 9

= 9/ 15

now it's 5/15 + 9/15

= 14/15

Jason made an error that he just added the denominators without applying any formula.

b. 11/12 - 5/6

find the lcm

= 12

11/ 12 × 1/1 = 11/12

5/6 × 2/2 = 10/12

11-10

= 1

= 1/12

Jason made a mistake that he said 12-6 instead of finding the LCD them multiplying that fractions

The errors Jason made that he did not take LCM of denominators.

In math, a denominator can be defined as the bottom number in a fraction that shows the number of equal parts an item is divided into.

Given are some calculations done by Jason,

We know that, to add two fractions, we take LCM of denominators and then divide the numerator by LCM and the add,

a) 1/3 + 3/5 = 4/8

Here, Jason have not taken LCM of denominators

Correction =

[tex]\frac{15(\frac{1}{3} )+15(\frac{3}{5}) }{15} \\= \frac{5+9}{15} \\=\frac{14}{15}[/tex]

b) 11/12 - 5/6 = 6/6 = 1

Again, the error is the same.

LCM(6, 12) = 12

Correction =

[tex]\frac{12(\frac{11}{12})+12(\frac{5}{6)} }{12} \\= \frac{11-10}{12} \\= \frac{1}{12}[/tex]
