Same Sides

When the sides are the same then the triangles are congruent. because they all have exactly the same sides. because the two triangles do not have exactly the same sides.

Answer:

b. 2/15

c. 7/15

Step-by-step explanation:

total frequency = 45

X 0 1 2 3 4 5 6 7

P(x) 1/45 7/45 2/45 1/15 4/45 1/9 2/15 7/45

b. P(≥4) = 18/45 = 2/5

c. P(<3) = 21/45 = 7/15

Answer:

$ 80 000

Step-by-step explanation:

provident fund -- x

Wife -- 1/2 of x

Son -- 1/4 of x

Two brothers -- x - (x/2 - x/4)

Therefore, x - (x/2 - x/4) / 2 = 10 000

x = 80 000

Therefore, the amount of provident fund is $ 80 000

Thenks and mark me brainliest :)

Answer:

Here's the answer! The mean will increase and the median will stay the same.

Step-by-step explanation:

The mean is the average, so if you have larger numbers, the mean will go up, since 6,000 was changed to 7,000 the mean will increase.

For the median, the median is the number in the middle so the other numbers don't really matter, because 7,000 would be the last number in the data set, (it will be last because to find the median you have to order the numbers in least to greatest) it won't change anything because, only the number in the middle numbers

Unrelated to the question but if you need to find the median and the data set has an even amount of numbers, take the 2 numbers in the "middle" and add them together and then divide them by 2.

Example: 3, 8, 17, 23

add 8 and 17 together, divide by 2, you will get 12.5

hence the median is 12.5 of the data set in the example.

Tip: if you have a larger data set, (more numbers, i'm not talking about the value of a number) try crossing out one number from each side, repeat until you get to the middle then you have your median, if there's an even amount of numbers, remember, add then divide by 2!

Hope this helps!

Dang I really took the time to type all that-

If this does help, I'd appreciate getting brainliest.

Have nice day!

Answer:

[tex]Length =5[/tex]

[tex]Width = 2[/tex]

Step-by-step explanation:

Given

[tex]Length =x[/tex]

[tex]Width = x -3[/tex]

[tex]Area = 10[/tex]

[tex]x(x-3) =10[/tex]

See comment for missing part of the question

Required

Complete the expression to determine the dimension of a rectangle

We have:

[tex]x(x-3) =10[/tex]

Open bracket

[tex]x^2 -3x = 10[/tex]

Equate to 0

[tex]x^2 -3x - 10 =0[/tex]

Expand

[tex]x^2 + 2x - 5x - 10 = 0[/tex]

Factorize

[tex]x(x + 2) - 5(x + 2) = 0[/tex]

Factor out x + 2

[tex](x - 5)(x + 2) = 0[/tex]

Solve for x

[tex]x - 5 = 0[/tex] or [tex]x + 2 = 0[/tex]

[tex]x = 5[/tex] or [tex]x = -2[/tex]

The value of x cannot be negative

So:

[tex]x = 5[/tex]

Recall that:

[tex]Length = x[/tex]

[tex]Width = x - 3[/tex]

So:

[tex]Length =5[/tex]

[tex]Width = 2[/tex] ---- i.e. 5 - 3

(5,-∞) this means any number which not include 5 and -∞

Answer:

75 students

Step-by-step explanation:

From the table, we can calculate the total number of students surveyed by Michael:

Total student surveyed = 13 + 15 + 32 = 60 students

We can see that out of the 60 students, 15 students played exactly one sport. Hence:

Proportion of students playing exactly one sport = 15 / 60 = 0.25

Based on the result of the survey, if they are 300 students, number of students playing exactly one sport is:

Number of students playing exactly one sport = proportion * total students = 0.25 * 300 students = 75 students

Answer:

261.8 in^3

Step-by-step explanation:

The volume of a right circular cone is  [tex]V=\frac{1}{3} \pi r^2h[/tex].

r is the radius of the circular base (r = 5 in this problem), and h is the height (h = 10 in this problem.

[tex]V=\frac{1}{3} \pi (5^2)(10)=\frac{1}{3}(250\pi) \approx 261.8\text{ in}^3[/tex]

Answer:

[tex] \displaystyle23.125 \: \text{pounds}[/tex]

Step-by-step explanation:

we are given that,

in order to figure out the weight of the larger bicycle we can consider using equation

let the weight of the larger bicycle be L

according to the second condition

we acquire

[tex] \displaystyle L = 18.5 \times 1\frac{1}{4} [/tex]

to simplify the mixed fraction to improper fraction we can use the formula given by

[tex] \displaystyle \rm c\frac{a}{b} \xrightarrow{ \text{improper fraction}} \frac{b \times c + a}{b} [/tex]

by using the formula we get

[tex] \displaystyle L = 18.5 \times \frac{5}{4} [/tex]

simplify multiplication:

[tex] \displaystyle L =\frac{92.5}{4} [/tex]

simplify division:

[tex] \displaystyle L =23.125[/tex]

hence,

the larger bicycle weighs 23.125 pounds

Answer:

x = -7/5

or x = -1.4

Step-by-step explanation:

2/10 - 4/5 = -3/5

-3/5 * 7 = -21/5
