can you please help me to understand.

Answer:

X=8

z=80

Step-by-step explanation:

Okay to find X you gotta find the other angle.

The other angle is 100 which is also vertical To (6x+52)

Vertical angles are equal or congruent so you cna make an eqaution to equal it

6x+52=100

Solve it like a normal equation

x=8

To find Z you gotta realize that 4 angles equal 360 degrees.

We knwo the two vertical angles, 100 and 100. Z is vertical to no name angle so its equal so it can also be Z. Z+Z=2z

Now If you add em all up you should get 360

2z+100+100=360

2z+200=360

Solve from here

z=80

Answer:

0.375 = 37.5% probability that two of the coins will land ‘heads’ up

Step-by-step explanation:

For each coin, there are only two possible outcomes. Either it lands heads, or it lands tails. The probability of a coin landing heads is independent of any other coin. This means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

Four well-balanced coins.

This means that [tex]n = 4, p = 0.5[/tex]

What are the odds that two of the coins will land ‘heads’ up?

This is P(X = 2).

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 2) = C_{4,2}.(0.5)^{2}.(0.5)^{2} = 0.375[/tex]

0.375 = 37.5% probability that two of the coins will land ‘heads’ up

Answer:

t=[tex]\sqrt{\frac{38}{g} }[/tex]

Step-by-step explanation:

19=(1/2)gt²

(multiply both sides by 2)

38=gt²

(divide both sides by g)

t²=(38/g)

(square root both sides)

t=[tex]\sqrt{\frac{38}{g} }[/tex]

Step-by-step explanation:

The number of times that josh rolled each number is given so the mean or average of the dice rolls​ is 3.6.

Probability is a branch of mathematics that deals with the study of random events or outcomes.

It is concerned with determining the likelihood of an event or outcome occurring in a given situation.

The probability of an event is a number between 0 and 1, with 0 indicating that the event is impossible and 1 indicating that the event is certain.

The average of dice roll is:

Average = 1/100 (15 x 1 + 18 x 2 + 14 x 3 + 16 x 4 + 19 x 5 +18 x 6)

Average = 1/100 (15 + 36 + 42 + 64 + 95 + 108)

Average = 1/100 x 36

Average = 3.6

Thus, the answer is 3.6.

The area of a composite shape is the sum of the areas of its individual shapes

The area of the composite shape is 215.20 square feet.

From the figures, we have the following shapes

The area (A) of a semicircle is:

[tex]\mathbf{A = \frac{\pi d^2}{8}}[/tex]

So, the area of the composite shape is:

[tex]\mathbf{A = \frac{\pi (d_1^2 + d_2^2)}{8}}[/tex]

This gives

[tex]\mathbf{A = \frac{\pi (22^2 + 8^2)}{8}}[/tex]

[tex]\mathbf{A = \frac{\pi (548)}{8}}[/tex]

[tex]\mathbf{A = 68.5\pi}[/tex]

[tex]\mathbf{A = 215.20}[/tex]

Hence, the area of the composite shape is 215.20 square feet.

first blank is "Permutation", i dont know what the second blank is but its not 17550

Step-by-step explanation:

This is an example of a permutation. There are 421,200 possible arrangements of first through fourth place winners.

"A permutation is an arrangement of objects in a definite order. The members or elements of sets are arranged here in a sequence or linear order."

We need to arrange 27 swimmers for 4 positions

Hence, the numbers are 27P4

= [tex]\frac{27!}{(27-4)!}[/tex]

[tex]=\frac{27.26.25.24.23!}{23!}[/tex]

[tex]=421,200[/tex]

Hence, the given situation is an example of permutation with 421,200 possible arrangements.

Answer:

Perimeter = 16 feet

Total Surface Area = 24 sq ft.

Step-by-step explanation:

Let's assume that each square is equal to 1 foot. Using this we can estimate the perimeter and area as the following. For perimeter, we simply add all the squares distances surrounding the shaded object.

Perimeter = 16 feet (4 feet for the top and bottom and 2 feet every diagonal)

For the area, we need to calculate the area of the square in the middle and then the area of the two triangles.

Square = L * W

Square = 4 * 4

Square = 16 sq ft

Triangle = 0.5 * Base * Height

Triangle = 0.5 * 4 * 2

Triangle = 4 sq ft

Both triangles = 4 sq ft * 2 = 8 sq ft.

Now we add both area totals:

Total Surface Area = 16 + 8

Total Surface Area = 24 sq ft.
