Answer:
17*12 area of triangle is base*height
Answer:
Use the formula for the area of a triangle:
A = BH x 1/2
Where 'B' represents the base, 'H' the height, and multiplying by 1/2 just means dividing the product of those two lengths by 2.
What we know:
Base = 12 feetHeight = 17 feetWhich is all we need to know, so plug these values into our formula;
A = BH x 1/2
A = 12(17) x 1/2
Now just solve:-
A = 204 x 1/2
A = 204/2
A = 102, the area of this triangle is 102 ft²!

Emily is working with rolling a standard number cube (die) and flipping a quarter.
Which experiment can yield a 50% probability?
Answer:
flipping a quarter
Step-by-step explanation:
a quarter has two sides so the chance of getting one is 1/2
a dice has 6 sides so the chance of getting a certain number is 1/6
brelynn has a piece of ribbon that is 3/4 yard long. how many 1/12 yard pieces can she cut? help
The Brelynn can cut 9 pieces from the piece of ribbon that is 3/4 yard long of 1/12 yard.
What is a fraction?Fraction number consists of two parts one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
Let's assume Brelynn can cut x pieces from the piece of ribbon that is 3/4 yard long.
So from the problem:
[tex]\rm \frac{\frac{3}{4} }{x} = \frac{1}{12}[/tex]
[tex]\rm \dfrac{3}{4} = \dfrac{x}{12}[/tex]
x = 9 pieces
Thus, the Brelynn can cut 9 pieces from the piece of ribbon that is 3/4 yard long of 1/12 yard.

-2-0.5b+12=0.3b+6.2
Step-by-step explanation:
-2 -0.5b + 12 = 0.3b + 6.2
-2 + 12 - 6.2 = 0.3b + 0.5b
3.8 = 0.8b
b = 3.8/0.8
= 4.75
Answer:
4.75
Step-by-step explanation:
-2-0.5b + 12 = 0.3b + 6.2
Move all terms to the left:
-2-0.5b + 12 - (0.3b + 6.2) = 0
Add all the numbers together, and all the variables
-0.5b - (0.3b + 6.2) + 10 = 0
Get rid of parentheses
-0.5b - 0.3b - 6.2 + 10 = 0
Add all the numbers together, and all the variables
-0.8b + 3.8 = 0
Move all terms containing b to the left, all other terms to the right
-0.8b = -3.8
b= -3.8/-0.8
b= 4+0.6/0.8
b= 4.75

The mean of five numbers is 8. If one of the five numbers is removed, the mean becomes 9. What is the value of the number that was removed
Using the mean concept, it is found that the value of the number that was removed was of 4.
What is the mean?The mean of a data-set is given by the sum of all observations in the data-set divided by the number of observations.
The mean of five numbers is 8, hence, the sum of the numbers is given by:
S = 5 x 8 = 40.
If one of the five numbers is removed, the mean becomes 9, hence, the sum of the four numbers is given by:
S = 4 x 9 = 36.
The difference is:
40 - 36 = 4.
Hence, the value of the number that was removed was of 4.

The equation of a circle is shown. What is the radius? 22 + y2 - 10x + 8y + 16 = 0
Answer:
radius = 5
Step-by-step explanation:
Given
x² + y² - 10x + 8y + 16 = 0Using completing the square method
x² - 10x + 25 - 25 + y² + 8y + 16 (x + 5)² + (y + 4)² - 25 = 0(x + 5)² + (y + 4)² = 25Standard form for equation of a circle
(x - h)² + (y - k)² = r², where r is the radiusOn comparison to our equation in the question :
r² = 25radius = 5 [as distances cannot be -ve]Answer:
radius = 5
Step-by-step explanation:
Question[tex]x^2+y^2-10x+8y+16=0[/tex]
The equation of a circle is shown. What is the radius?
----------------------------------------------------------------------------------
Equation of a circle
[tex](x-a)^2+(y-b)^2=r^2[/tex]
(where (a, b) is the center and r is the radius)
Given equation:
[tex]x^2+y^2-10x+8y+16=0[/tex]
Collect like terms:
[tex]\implies x^2-10x+y^2+8y+16=0[/tex]
Subtract 16 from both sides:
[tex]\implies x^2-10x+y^2+8y=-16[/tex]
Complete the square for both variables.
Add 25 to both sides for x. Add 16 to both sides for y.
[tex]\implies x^2-10x+25+y^2+8y+16=-16+25+16[/tex]
[tex]\implies (x^2-10x+25)+(y^2+8y+16)=25[/tex]
Factor the two variables:
[tex]\implies (x-5)^2+(y+4)^2=25[/tex]
Therefore:

An equation is shown.
4c + 2c = 4c + 11/2
What value of 2c makes the equation true?
Answer:
[tex]\huge\boxed{\bf\:c = \frac{11}{4}}[/tex]
Step-by-step explanation:
[tex]4c + 2c = 4c + \frac{11}{2}[/tex]
Cancel 4c on both the sides of the equation.
[tex]2c = \frac{11}{2}[/tex]
Bring the 2 in the denominator of 11/2 to the left hand side of the equation.
[tex]2*2c = 11\\4c = 11[/tex]
Bring 4 to the right hand side if the equation.

Suppose you carry out a significance test of h0: μ = 8 versus ha: μ > 8 based on sample size n = 25 and obtain t = 2. 15. Find the p-value for this test. What conclusion can you draw at the 5% significance level? explain.
a the p-value is 0. 2. We reject h0 at the 5% significance level because the p-value 0. 02 is less than 0. 5.
b the p-value is 0. 2. We fail to reject h0 at the 5% significance level because the p-value 0. 02 is less than 0. 5.
c the p-value is 0. 48. We reject h0 at the 5% significance level because the p-value 0. 48 is greater than 0. 5.
d the p-value is 0. 48. We fail to reject h0 at the 5% significance level because the p-value 0. 48 is greater than 0. 5.
e the p-value is 0. 52. We fail to reject h0 at the 5% significance level because the p-value 0. 52 is greater than 0. 5
Using a t-distribution calculator and finding the p-value, the correct option regarding the conclusion is given by:
a) the p-value is 0.02. We reject h0 at the 5% significance level because the p-value 0.02 is less than 0.05.
What is the relation between the p-value and the conclusion?It also involves the significance level, as follows.
If the p-value is less than the significance level, we reject the null hypothesis [tex]h_0[/tex].If it is more, we do not reject.In this problem, a t-distribution calculator for a right-tailed with t = 2.15 and 25 - 1 = 24 df is used to find a p-value of 0.02.
It is less than 0.05, hence option a is correct.
