Find the value of x.
Answers
Answer:
x = 62°
Step-by-step explanation:
the top-most angle in the top isosceles triangle must be 73° also
the third angle of the top isosceles triangle is (180 - 73 + 73) which is 34°
the left portion of the right angle must be 56°
you can find by using this equation: x + x + 56 = 180
2x = 124
x = 62

Two similar polygons are shown below. Find the value of x and y.
Answers
Answer:
x = 3
y = 12
Step-by-step explanation:
(2x+1) / 3 = (4x+9) / 9
cross-multiply:
18x + 9 = 12x + 27
6x = 18
x = 3
3/4 = 9/y

4. A comprehensive study conducted by the National Institute of Child Health and Human Development tracked more than 1,000 children from an early age through elementary school (New York Times, November 1, 2005). The study concluded that children who spent more time than 30 hours a week in child care before entering school tended to score higher in math and reading when they were in the third grade. The researchers cautioned that the findings should not be a cause for alarm because the differences were found to be small. Explain how the difference between the math and reading score for the child care group and the overall mean for third graders could be small but the researchers could still reach the conclusion that the mean for the child care group is significantly higher than the overall mean.

The price of a calculator is increased by 99 % and now is $ 883.56 . Find the original price.
Answers
Answer:
$444
Step-by-step explanation:
1.99 * x = 883.56 [The price has increased by 99%, so you multiply it by 1 + 0.99]
x = 444
Answer:
The original price of the calculator was $444
Step-by-step explanation:
So follow this equation
1.99x=883.56
1.99 becuase 99 percent is the .99 and since the original price with no change of all is worth 100 percent With no sales or increases, we add the 99 percent this time becuase it increased by 99%.
X is for the original price of the calculator
If you still don’t undertsand it works like this.
100% is basically 1.00 becuase you move the decimal place 2 times to the left for percentages. And if you multiply the original price by 100 percent, its basically 1x which will end up with x. Same thing. But when you increase a price, you add to the 1.00 like in this case 99% increase which is adding .99 to 1.00. If it decreases same thing except you subtract from that 1.00 But the percent. this saves a whole nother step Which makes percentage questions liek these much quicker and easier.
Alright so the eqaution is 1.99x=883.56
Solve by isolating x by dividing 1.99 on both sides
You’d get 444=x
$444 is the original price

60 POINTS! PLEASE ANSWER, NO SPAM
Answers
Answer:
1. D= 46 degrees
2. X= 50 degrees
3. X= 180-118 = 62 degrees
4. X = 90-75 = 15 degrees.
Step-by-step explanation:
Answer:
Going by the order from the first row left to right and then second row left to right
1) D=46
2) x=62
3) x=50
4) x=15
5) b=40
Step-by-step explanation:
So for the first column for the first question its a complementary angle which means 2 or more angles added up to from a 90 degrees angle. We got 44 degrees already and an unknown angle which will lead to 90-44= 46 and that 46 degrees is your answer. D will be equal to 46.
For the second question on the first column, you have 2 angles forming a straight line. This is a s upplementary angle which means 2 or more angles added up to from 180 degrees. You have 1 angle already which is 118 and to find the other angle, 180-118 which will be 62. X will equal to 62
For the thrid question which is the first question on the SECOND column, you have another supplementary angle. You have 130 and 180-130=50 and X will equal to 50.
For the 4th question you have a complementary and one angle is 75. You do 90-75 and get 15. X will equal to 15.
The last question which is the huge rectangle on the right, you have 2 intersecting lines. We know one side is 40. Well the only thing that makes sense here is B=40 since its vertical to the one angle given. Vertical angles are equal so therfore the answer is b=40

A fair tossed 10 times . Find the probability of obtaining (i) exactly four heads (ii) 3 heads and 7 tails (iii) at least one head
Answers
Answer:
0.205 ; 0.117 ; 0.999
Step-by-step explanation:
Using binomial probability distribution :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
Probability of success, p = 0.5
P(x = 4) = 10C4 * 0.5^4 * 0.5^6
P(X = 4) = 0.205078125
B.) 3 heads and 7 tails
P(X = 7) = 10C7 * 0.5^7 * 0.5^3
P(X = 7) = 120 * 0.0009765625
P(X = 7) = 0.117
P(atleast one head)
P(x greater than equal to 1) = p(x =1) +... P(x = 10)
Using a binomial probability calculator :
P(x greater than equal to 1) = 0.999

Write a quadratic function whose zeros are 12 and 2 .
Answers
Answer:
The quadratic function is: [tex](x-2)(x-12)=0[/tex] and can be written as: [tex]x^2-14x+24=0[/tex]
Step-by-step explanation:
A quadratic function can typically be written in multiple forms, among which includes: (x-a)*(x-b)=0 where a, b can be any number
This quadratic function is solved for a and b, which represents the zeroes (or can be called roots) of the equation.
Given that the zeroes are already given, all that's need to write the quadratic function is to substitute a and b with the given zeroes:
Note: It doesn't matter which zeroes are substituted for a and b
(x-a)*(x-b)=0
(x-2)*(x-12)=0
Now, we can leave it in this form or expand the equation (often called the FOIL method):
(x-2)*(x-12)=0 Multiply each term with the other terms
[tex]x^2-2x-12x+24=0[/tex] Simplify by combining like terms
[tex]x^2-14x+24=0[/tex]
Thus, the quadratic function for zeroes 12 and 2 is: [tex]x^2-14x+24=0[/tex]

Congruent: Choose one of the vertical angle pairs I listed above
Step-by-step explanation:
Vertical angles are diagonally across for each other and equal the same angle. You would get a better explanation if you looked up pictures.
Linear angles are two angles on a straight line that are divided by another line. Again, you would get a better explanation by looking at a visual
Congruent angles are equal to each other, and because there are no angle measures here, you would go with a vertical angle pair.

Answers
Answer:
x = 6
Step-by-step explanation:
Tip: You want to isolate the x-variable on one side of the equation to find its value.
1) First, get rid of the radical signs on both sides of the equation by squaring both sides. This should leave you with 5x-7 = 3x+5.
2) Get the x-variables on one side by subtracting 3x from both sides, so the equation should be 2x-7=5.
3) Solve for x by adding 7 to both sides, so that your equation looks like this: 2x = 12.
4) Divide both sides by 2 and you will get x = 6. You can verify 6 as the x-value by plugging 6 back into the original equation.
I hope that helps! :)
