Please help me solve for Z
The correct value of z in this figure is 190⁰
The image given in this question is of a circle. To solve it, let's calculate it as an equation of the first degree.
– First, let's: add the data that are on the circle and equate the equality as 360⁰, which is the value of the degree of a circle.
145 + 24 + z = 360⁰
– Now, let's: add the natural terms to each other. And finally, we'll isolate z and subtract 360⁰ by the number that's left.
145 + 24 + z = 360⁰
170 + z = 360⁰
z = 360⁰ - 170
z = 190⁰
So, the value of z, will be 190⁰
Mickey tosses a coin 50 times and records 27 heads. Based on these results, what is the probability if
Mickey tosses the same coin three more times, she will get three tails?
a) 112,833: 125,000
b) 23:50
c) 69:50
d) 12,167: 125,000
The probability of getting three tails in three tosses When Mickey tosses a coin 50 times and records 27 heads is 12,167:125,000.
What is probability of an event?It is the ratio in an event of the number of favorable outcome to the total number of outcome of that event.
As the probability of an event can not be more than the number 1. Thus, he probability of failure of a event is equal to the difference of the 1 to the success of the event.
Mickey tosses a coin 50 times and records 27 heads. Thus, the probability of getting a head is,
[tex]P=\dfrac{27}{50}\\[/tex]
The probability of not getting a head or getting a tail is,
[tex]P^{-1}=1-\dfrac{27}{50}\\P^{-1}=\dfrac{50-27}{50}\\P^{-1}=\dfrac{23}{50}[/tex]
Now, Mickey tosses the same coin three more times. The probability of getting three tails in these tosses are,
[tex]P_{3t}=\dfrac{23}{50}\times\dfrac{23}{50}\times\dfrac{23}{50}\\P_{3t}=\dfrac{12167}{125000}[/tex]
Thus, the probability of getting three tails in three tosses When Mickey tosses a coin 50 times and records 27 heads is 12,167:125,000.

What is the common difference between successive terms in the sequence? 2, 8, 14, 20, 26,. –6 –4 4 6.
Answer:
The common difference is the difference between any two consecutive terms in an arithmetic sequence.
The formula which is used to find the common difference in AP is
d = an - an-1
Here the common difference is
d = a2 - a1 = 8 - 2 = 6
d = a3 - a2 = 14 - 8 = 6
d = a4 - a3 = 20 - 14 = 6
d = a5 - a4 = 26 - 20 = 6
2, 8, 14, 20, 26 … = 2, (2 + 6), (8 + 6), (14 + 6), (20+ 6) …
Therefore, the common difference is 6.

what is an isosceles triangle?An isosceles triangle is a type of triangle with base angles equal and opposite sides equal.
Analysis:
Since GF = EF
∠FGE = ∠FEG = (x - 18)°( base angles of an isosceles triangle are equal)
∠FGE + ∠FEG + ∠GFE = 180°( sum of angles in a triangle)
(x - 18)° + (x-18)° + 66 = 180
2x -36 + 66 = 180°
2x + 30 = 150
2x = 180 - 30
2x = 150°
x = 150/2 = 75°
In conclusion, the value of x in the diagram is 75°

Choose the histogram that has the smallest variance.
The histogram first represents the smallest variance option first is correct.
What is a histogram?It is defined as the depiction of numerical data in a graph using a bar with no space. The histogram depicts the approximate distribution of the data.
We have four histograms shown in the picture.
As we know in a histogram, the curves that resemble hills show groupings of statistics that are close collectively, leading to low variation.
Whenever the taller bars are farther away from the mean in a histogram, the variability is greater, and when the taller bars are closer to the mean, the variability is less.
In the histogram first, there is very less variability.
Thus, the histogram first represents the smallest variance option first is correct.

19. Solve for the angle x.
sin²(2x) = 1
Answer: Е
Step-by-step explanation:
▪︎ a^2 - b^2 = (a-b)(a+b)
sin^2(2x) = 1
sin^2(2x) - 1 = 0
(sin2x - 1)(sin2x + 1) = 0
sin2x - 1 = 0 or sin2x + 1 = 0
sin2x - 1 = 0
sin2x = 1
2x = 90° + 360°n
x = 45° + 180°n
▪︎180° means half of the unit circle, therefore,
x = 45° + 360°n and
x = 45° + 180° + 360°n = 225° + 360°n
sin2x + 1 = 0
sin2x = -1
2x = 270° + 360°n
x = 135° + 180°n
therefore,
x = 135° + 360°n and
x = 135° + 180° + 360°n = 315° + 360°n

the names of 2 students at random as team leaders for
a volleyball game. how many different pairs of team
leaders could she choose?
Considering the definition of combination, she could choose 190 different pairs of team.
What is combinationCombinations of m elements taken from n to n (m≥n) are called all the possible groupings that can be made with the m elements in such a way that not all the elements enter; the order does not matter and the elements are not repeated.
To calculate the number of combinations, the following formula is applied:
[tex]C=\frac{m!}{n!(m-n)!}[/tex]
The term "n!" is called the "factorial of n" and is the multiplication of all numbers from "n" to 1.
Different pairs of team leadersMs. lewis has 20 students in her p.e. class. She puts each student's name in a hat and will select the names of 2 students at random as team leaders for a volleyball game.

a.240 grams
b.244 grams
c.250 grams
d.256 grams
Answer:
Step-by-step explanation:
Remark
An amount no 9 people could consume. 114 kg is a huge amount of cooked rice. I' going to give a solution that says the rice is 114 grams of rice and see what happens.

rice = 114 grams
veggies = 500 grams
meat = 410 grams
Solution
Add the givens

500
410
