What is the equation of the blue line?
Answer:
y = 4x - 3
Step-by-step explanation:
Find two point of the line
(0,-3) ; (1,1)
Use this formula
(y - y1)/(y2-y1) = (x-x1)/(x2-x1)
(y-(-3)/(1-(-3) = (x-0)/(1-0)
(y+3)/4 = x
y+3 = 4x
y = 4x -3
Answer:
y = 4x -3
Step-by-step explanation:
The y intercept is (0,-3)
Using another point on the line (1,1), we can find the slope
m = (y2-y1)/(x2-x1)
m = (1 - -3)/(1-0)
= (1+3)/(1-0)
= 4/1
The equation for a line in slope intercept for is
y = mx+b where m is the slope and b is the y intercept
y = 4x -3

we all know that the total of degrees is 180 so 70+70=140
180-140=40
so the answer is 40
3:
we have a figure with 4 angle so the total of degrees is 360 so the answer is 126
4:
the answer most be 50 becuse we have a Special degree witch always equal 90 if we have recatngle so
x+40=90

The measure of one angle of a right triangle is 56∘ more than the measure of the smallest angle. Find the measure of the smallest angle.
Answer:
The sum of all angels for any triangle equals 180°
so we have a right triangle which means we have an angle equals 90° ,angle equals=56°.
step by step
[tex]180 - 56 - 90 = 34[/tex]
so the angle tends to equal 34°.

A square table 4 feet on each side has two drop leaves, each a semicircle 4 feet in diameter.
Find the area of the table with and without the drop leaves.
1) With Drop Leaves (Semicircles are attached to table) =
ft. 2
2) Without Drop Leaves (Semicircles are not attached to table)
ft 2
4 ft
|4ft
Answer:
Area of table with leaf = 28.56 feet²
Area of table without leaf = 16 feet²
Step-by-step explanation:
Given:
Side of square table = 4 feet
Diameter of side leaf = 4 feet
Number of semicircle leaf = 2
Find:
Area of table without leaf
Area of table with leaf
Computation:
Area of square = Side x Side
Area of table without leaf = 4 x 4
Area of table without leaf = 16 feet²
Radius of side leaf = Diameter of side leaf / 2
Radius of side leaf = 4 / 2
Radius of side leaf = 2 feet
Area of table with leaf = Area of table without leaf + 2[πr²/2]
Area of table with leaf = 16+ 2[πr²/2]
Area of table with leaf = 16+ (3.14)(2)²
Area of table with leaf = 16+ (3.14)(4)
Area of table with leaf = 16+ 12.56
Area of table with leaf = 28.56 feet²

A fabric manufacturer believes that the proportion of orders for raw material arriving late isp= 0.6. If a random sample of 10 orders shows that 3 or fewer arrived late, the hypothesis thatp= 0.6 should be rejected in favor of the alternativep <0.6. Use the binomial distribution.(a) Find the probability of committing a type I error if the true proportion isp= 0.6.(b) Find the probability of committing a type II error for the alternative hypothesesp= 0.3,p= 0.4, andp= 0.5
Answer:
a) the probability of committing a type I error if the true proportion is p = 0.6 is 0.0548
b)
- the probability of committing a type II error for the alternative hypotheses p = 0.3 is 0.3504
- the probability of committing a type II error for the alternative hypotheses p = 0.4 is 0.6177
- the probability of committing a type II error for the alternative hypotheses p = 0.5 is 0.8281
Step-by-step explanation:
Given the data in the question;
proportion p = 0.6
sample size n = 10
binomial distribution
let x rep number of orders for raw materials arriving late in the sample.
(a) probability of committing a type I error if the true proportion is p = 0.6;
∝ = P( type I error )
= P( reject null hypothesis when p = 0.6 )
= ³∑[tex]_{x=0[/tex] b( x, n, p )
= ³∑[tex]_{x=0[/tex] b( x, 10, 0.6 )
= ³∑[tex]_{x=0[/tex] [tex]\left[\begin{array}{ccc}10\\x\\\end{array}\right][/tex][tex](0.6)^x[/tex][tex]( 1 - 0.6 )^{10-x[/tex]
∝ = 0.0548
Therefore, the probability of committing a type I error if the true proportion is p = 0.6 is 0.0548
b)
the probability of committing a type II error for the alternative hypotheses p = 0.3
β = P( type II error )
= P( accept the null hypothesis when p = 0.3 )
= ¹⁰∑[tex]_{x=4[/tex] b( x, n, p )
= ¹⁰∑[tex]_{x=4[/tex] b( x, 10, 0.3 )
= ¹⁰∑[tex]_{x=4[/tex] [tex]\left[\begin{array}{ccc}10\\x\\\end{array}\right][/tex][tex](0.3)^x[/tex][tex]( 1 - 0.3 )^{10-x[/tex]

= 1 - 0.6496
= 0.3504
Therefore, the probability of committing a type II error for the alternative hypotheses p = 0.3 is 0.3504
the probability of committing a type II error for the alternative hypotheses p = 0.4
β = P( type II error )
= P( accept the null hypothesis when p = 0.4 )
= ¹⁰∑[tex]_{x=4[/tex] b( x, n, p )
= ¹⁰∑[tex]_{x=4[/tex] b( x, 10, 0.4 )
= ¹⁰∑[tex]_{x=4[/tex] [tex]\left[\begin{array}{ccc}10\\x\\\end{array}\right][/tex][tex](0.4)^x[/tex][tex]( 1 - 0.4 )^{10-x[/tex]

= 1 - 0.3823
= 0.6177
Therefore, the probability of committing a type II error for the alternative hypotheses p = 0.4 is 0.6177
the probability of committing a type II error for the alternative hypotheses p = 0.5
β = P( type II error )
= P( accept the null hypothesis when p = 0.5 )
= ¹⁰∑[tex]_{x=4[/tex] b( x, n, p )
= ¹⁰∑[tex]_{x=4[/tex] b( x, 10, 0.5 )
= ¹⁰∑[tex]_{x=4[/tex] [tex]\left[\begin{array}{ccc}10\\x\\\end{array}\right][/tex][tex](0.5)^x[/tex][tex]( 1 - 0.5 )^{10-x[/tex]

= 1 - 0.1719
= 0.8281
Therefore, the probability of committing a type II error for the alternative hypotheses p = 0.5 is 0.8281
The probability of committing a type I is 0.0548, type II error for p = 0.3 is 0.3504, type II error for p = 0.4 is 0.6177, type II error for s p = 0.5 is 0.8281.

Answer:
the area is 207
Step-by-step explanation:
The equation to solve the area of a cylinder is A=2πrh+2πr^2
The radius is the length from the outside to the center, 6 is the diameter so we could half that to get the radius, 3 and height is 8
A=2*3.14*3*8+2*3.14*3^2
A=6.28*3*8+6.28*9
A=18.84*8+56.52
A=150.72+56.52
A=207.24
207.24 rounded to the nearest whole number is 207 so your area is 207

One pipe can fill a tank in 4 hours. A second pipe also requires 4 hours, but a third
needs three hours. How long will it take to fill the tank if all three pipes are open?
Answer:
Step-by-step explanation:
We will use the idea here that the first 2 pipes can get 1/4 of the job done in an hour, and that the third pipe can get 1/3 of the job done in an hour. We need to know then the number of hours it will take to fill the tank if all 3 work together. The equation looks like this:
[tex]\frac{1}{4}+ \frac{1}{4}+ \frac{1}{3}= \frac{1}{x}[/tex] Now we find a common denominator and solve for x. The common denominator is 12x. Multiplying everything by 12 x gives us
3x + 3x + 4x = 12 and
10x = 12 so
x = 1.2 hours
Answer:
1.2 hours
Step-by-step explanation:
we need to see how much each pipes does in the same amount of time
The least common multiple of 3 hours and 4 hours is 12 hours
In 12 hours:
Pipe 1 at 4 hours to fill a tank fills 3 tanks
Pipe 2 at 4 hours to fill a tank fills 3 tanks
Pipe 3 at 3 hours to fill a tank fills 4 tanks
All three pipes can fill 10 tanks in 12 hours
12 hours/10 tanks = 1.2 hours to fill one tank
-------------------------
Doing just the math
1/4 + 1/4 + 1/3 = x
3/12 + 3/12 + 4/12 = 10tanks/12 hours
12hours/10tanks = 1.2 hours

17x6
66x6
66x5
Answer:
A = 66×6 cm²
Step-by-step explanation:
Given that,
The width of a rectangular garden, w = (6x2) cm
The length of a rectangular garden, l = (11x2) cm
We need to find the area of Ms. Alberta’s garden. The area of a rectangular garden is given by :
A = LW
Put all the values,
A = (6x2) × (11x3)
= (11×6)(2×3)
= 66×6 cm²
Hence, the area of the Ms. Alberta’s garden is 66×6 cm².

To compare the effectiveness of two treatments, researchers conducted a well-designed experiment using a randomized block design in which the subjects were blocked by age-group (under 40 years and 40 years or older). Which of the following must be true about the randomized block design of the experiment?
(A) The number of subjects in each block is different.
(B) Treatments are randomly assigned to subjects within each block.
(C) The design cannot have a control group because subjects are blocked by age-group.
(D) The experiment uses a matched-pairs design, where subjects from one block are paired with subjects from the other block.
(E) The subjects in one block receive one treatment, and the subjects in the other block receive the other treatment.
Answer:
(B) Treatments are randomly assigned to subjects within each block.
Step-by-step explanation:
In the case when the comparison of the treatments should be done so the researcher want to conducted the experiment where the subjects were blocked by the age group so here the option b is considered as in this the treatments would be allocated on the randomly basis to the subject with respective to the each and every block
Rest of the options are wrong as the number of subjects are same, the design have the control and there is same replication of the number

Find the equation of the linear function represented by the table below in slope-
intercept form.
9514 1404 393
Answer:
y = -4x -2
Step-by-step explanation:
The slope is given by the formula ...
m = (y2 -y1)/(x2 -x1)
m = (-10 -10)/(2 -(-3)) = -20/5 = -4
__
The y-intercept is given by ...
b = y1 -m(x1)
b = 10 -(-4)(-3) = 10 -12 = -2
Then the slope-intercept equation is ...
y = mx +b
y = -4x -2
In ΔWXY, the measure of ∠Y=90°, YX = 40, XW = 41, and WY = 9. What ratio represents the cosine of ∠W?
Answer:
[tex]\cos{W} = \frac{9}{41}[/tex]
Step-by-step explanation:
Cosine of an angle:
The cosine of an angle, in a right triangle, is the length of the side adjacent to this angle divided by the hypotenuse.
Length of the largest side:
The length of the largest side is 41, that is, the hypotenuse is 41. The hypotenuse is XW.
WY = 9.
This means that the length of the adjacent side to angle W is 9.
What ratio represents the cosine of ∠W?
Adjacent side has length 9, hypotenuse has length 41. So
[tex]\cos{W} = \frac{9}{41}[/tex]
