Answer:
18.5
Step-by-step explanation:
You are given the opposite side, and need to find the hypotenuse, leading you to use sine.
Set it up, like so:
[tex]sin67=\frac{17}{x} \\[/tex]
Multiply everything by x, to remove it from the denominator:
[tex]x(sin67=\frac{17}{x} )\\xsin67 = 17[/tex]
Divide both sides by sin67:
[tex]x = \frac{17}{sin67} \\x = 18.46[/tex]
Round to nearest tenth:
x = 18.5
Two sides is a triangle have the following measures. Find the range of possible measures for third side.
Answer:
last one
Step-by-step explanation:
the least is 10. so 10 plus one of the number is always greater than the other number. The max is 62. 62 plus any number is greater than the othe
6 < x < 64
Therefore, option b) is correct.
Step-by-step explanation:
Given :
Two sides of the triangle -- 35 , 29
Solution :
Let y, z and x are the sides of the triangle and given that y = 35 and z = 29.
Then ,
y - z < x < y + z
35 - 29 < x < 35 + 29
6 < x < 64
Therefore, option b) is correct.

2. An advertiser wants to find convincing evidence that television viewers
remember more than 4 commercials, on average, after watching a 30 minute TV
program. They take a random sample of 100 television viewers and ask them
how many commercials they could remember after watching a 30 minute TV
program. The appropriate t-test was conducted, which resulted in a P-value of
0.15. Assuming all conditions were met, which of the following is an appropriate
conclusion?
(A) Because the P-value is less than 0.05, at the 5% significance level, there is not
convincing evidence that television viewers remember more than 4 commercials, on
average, after watching a 30 minute TV program.
(B) Because the P-value is greater than 0.05, at the 5% significance level, there is
convincing evidence that television viewers remember fewer than 4 commercials, on
average, after watching a 30 minute TV program.
(C) Because the P-value is greater than 0.01, at the 1% significance level, there is not
convincing evidence that television viewers remember more than 4 commercials, on
average, after watching a 30 minute TV program.
(D) Because the P-value is greater than 0.01, at the 1% significance level, there is
convincing evidence that television viewers remember exactly 4 commercials, on
average, after watching a 30 minute TV program.
(E) Because the P-value is less than 0.01, at the 1% significance level, there is convincing
evidence that television viewers remember fewer than 4 commercials, on average, after
watching a 30 minute TV program.

The diameter of a circle is 6
inches. What is its
approximate
area?
Answer:
A =28.26 inches^2
Step-by-step explanation:
The diameter is 6 so the radius is d/2 = 3
The area is given by
A = pi r^2
A = pi (3)^2
A = 9pi
Using 3.14 for pi
A = 9 * 3.14
A =28.26 inches^2
Answer:
~28.2743
Step-by-step explanation:
- The formula for a circle's area is: Area= pi * radius^2
1.) We know the diameter is 6, and the radius is ALWAYS half of the diameter so the radius=3.
2.) Now we square the radius and multiply it by pi, which ends up as ~28.2743 as the area.
4x2 + 4x =- 4
Find the solutions to the Quadratic equation.
Answer:
x=-3
Step-by-step explanation:
(4)(2) + 4x = -4
multiply the 4 and 2
8 + 4x = -4
subtract 8 from both sides
4x = -12
divide both sides by 4
x = -3
Answer:
x = 1/2
Step-by-step explanation:
Step 1: Isolate x's
4x² - 4x + 1 = 0
Step 2: GCF
4(x² - x + 1/4) = 0
x² - x + 1/4 = 0
Step 3: Factor
(x - 1/2)² = 0
Step 4: Solve
√(x - 1/2)² = √0
x - 1/2 = 0
x = 1/2

You have a jar of marbles with 7 red, 12 blue, 6 yellow, and 9 white. What is the probability of selecting a marble that is not red, replacing it and then one that
is white?
Answer:
The probability of selecting a marble that is not red, replacing it and then one that is white is 0.2102
Step-by-step explanation:
Number of red marbles = 7
Number of blue marbles = 12
Number of yellow marbles = 6
Number of white marbles = 9
Total marbles = 7+12+6+9=34
Probability of selecting red marble =[tex]\frac{7}{34}[/tex]
Probability of selecting no red marble = [tex]1-\frac{7}{34}=\frac{27}{34}[/tex]
Now replacing it one marble is drawn again
So, Probability of getting white marble [tex]=\frac{9}{34}[/tex]
So,the probability of selecting a marble that is not red, replacing it and then one that is white =[tex]\frac{27}{34} \times \frac{9}{34}=0.2102[/tex]
Hence the probability of selecting a marble that is not red, replacing it and then one that is white is 0.2102

Answer:
30 degrees
Step-by-step explanation:
first you have to find angle TSU which is 70 degrees
you get this my doing 180 - 110
then you add up all the angles in the triangle
so, 80 plus 70
you get 150
then you do 180 - 150 and get 30 degrees

Which is a solution to 2x + 1 = 21?
Answer:
x = 10 is your answer
- Explain -
Step 1: subtract 1 from both sides (subtraction of equality)
which will give us:
2x = 21 - 1
which equals to
2x = 20
Step 2: Divide both sides by 2
which is
2x/2 = 20/2
2/2 = 1 and 20/2 = 10
Therefore the answer is x = 10
find the solution of this system of equations
-10x-6y=0
-4x-6y=54
Should be an answer like 0,0
Answer:
(9, -15)
Step-by-step explanation:
First, label the 2 equations:
-10x -6y= 0 -----(1)
-4x -6y= 54 -----(2)
(2) -(1):
(-4x -6y) -(-10x-6y)= 54 -0
-4x -6y -(-10x) -(-6y)= 54 (expand, simplify)
-4x -6y +10x +6y= 54 (expand)
10x -4x= 54 (simplify)
6x= 54
x=54 ÷6
x= 9
susbt. x=9 into (1):
-10(9) -6y=0 (subst. x=9 into -10x-6y=0)
-90= 6y (bring y term to the other side)
6y= -90
y= -90 ÷6
y= -15
Thus, the solution is (9, -15).
The value of X is 9.
The value of y is -15.
