Answer:
[tex]y = \frac{1}{6}x - 4[/tex]
[tex]y = \frac{x}{2} + 2[/tex]
[tex]y = \frac{1}{8}x[/tex]
[tex]y = \frac{1}{6}x+ \frac{2}{3}[/tex]
[tex]y = 12x - 9[/tex]
Step-by-step explanation:
Required
Represent in gradient intercept form
This means that the equation be in form: [tex]y = mx + c[/tex]
Solving (a): [tex]3y = \frac{1}{2}x - 12[/tex]
Divide through by 3
[tex]\frac{3y}{3} = \frac{1}{3*2}x - \frac{12}{3}[/tex]
[tex]y = \frac{1}{6}x - 4[/tex]
Solving (b): [tex]5x = 10y - 20[/tex]
Make y the subject
[tex]10y = 5x + 20[/tex]
Divide through by 10
[tex]y = \frac{5x}{10} + \frac{20}{10}[/tex]
[tex]y = \frac{x}{2} + 2[/tex]
Solving (c): [tex]x = 8y[/tex]
Make y the subject
[tex]8y= x[/tex]
Divide through by 8
[tex]y = \frac{1}{8}x[/tex]
Solving (d): [tex]\frac{1}{2}x = 3y - 2[/tex]
Make y the subject
[tex]3y = \frac{1}{2}x+ 2[/tex]
Divide through by 3
[tex]y = \frac{1}{2*3}x+ \frac{2}{3}[/tex]
[tex]y = \frac{1}{6}x+ \frac{2}{3}[/tex]
Solving (d): [tex]\frac{2}{3}y - 8x = -6[/tex]
Make y the subject
[tex]\frac{2}{3}y = 8x -6[/tex]
Divide through by 3/2
[tex]\frac{3}{2} * \frac{2}{3}y =\frac{3}{2} * ( 8x -6)[/tex]
[tex]y =\frac{3}{2} * ( 8x -6)[/tex]
[tex]y =\frac{3}{2} * 8x -\frac{3}{2} * 6[/tex]
[tex]y = 3 * 4x - 3 * 3[/tex]
[tex]y = 12x - 9[/tex]

Answer: 13
Step-by-step explanation:
A researcher is trying to show evidence for extra-sensory perception (ESP). She performs a test in which the subject is asked 10 yes or no question whose answer depends on information which the subject has not observed. Suppose that for each test, in the absence of ESP, the subject gets each question correct with 50% probability a) In the absence of ESP, what is the probability that a given test subject will answer at least 8 out of 10 questions correctly
Answer:
The answer is "0.0547".
Step-by-step explanation:
[tex]P(Correct) = 0.50\\\\n = 10\\\\x = 8[/tex]
Using the binomial distribution:
[tex]\to P(x,n) = n_{C}_x \times p^x \times (1-p)^{(n-1)}\\\\\to P(x \geq 8) = 1 - P( \leq 7)[/tex]
Calculating the excel formula:
[tex]=BINOM.DIST(7,10,0.50,TRUE)[/tex]
[tex]\to P(x \geq 8) = 1 - 0.9453\\\\ \to P(x \geq 8) = 0.0547[/tex]

2*5=10
Can I plz have brainliest?
Answer: The answer is B or some people say its 2, and others #2: 20 cups of grade juice, and 10 cups of apple juice.
Step-by-step explanation: Ok so if there are 4 cups of grape juice and 2 cups of apple juice the we need to multiply both of them by 5 because it says what does she need to make 5 TIMES or x the recipe so 4x5=20 for grape juice and 2x5=10 for apple juice so The answer is B or some people say its 2, and others #2: 20 cups of grade juice, and 10 cups of apple juice.

A sample of six repair records for a different type of fiber optic component was drawn. The repair costs, in dollars, were as follows. 93 97 27 79 81 87 Would it be appropriate to compute a 95% confidence interval for the population standard deviation of the costs
Answer:
The answer is "This is the right thing. There might be a surface sample which indicates that the population is not regular".
Step-by-step explanation:
When the community is ordinary or a biosensor, a normal distribution could be calculated for the dependent variable. Data shows chi-squared distributions of n-1 degrees - of - freedom about the dependent variable.
Chi-square was its precise outcome for the data set, while chi-square is a close estimate for non-normal information. So, we should also calculate CI for uncommon information. Throughout the case of an outlier, however, data refers to non because as mean tends to move in a skewed direction to the outer surface.

1) Lisa is cooking muffins. The recipe calls for 7 cups of sugar. She has already put in 2 cups. How many more cups does she need to put in?
Answer:
she needs to put in 5 more cups of sugar.
Step-by-step explanation:
in the word problem it states that shee needs 7 cups of sugar and since she already put in 2 cups, you have to subtract 2 from 7 since she already put 2 cups in, and then you get your answer which is 5 more cups.

Raul's hunting club membership costs $130 plus $45 per month. Which equation represents the cost of membership for x months?
Answer:
[tex]y = 130 + 45x[/tex]
Step-by-step explanation:
Given
[tex]Base = 130[/tex]
[tex]Monthly = 45[/tex]
Required
The cost for x months
Represent this cost with y.
So:
[tex]y = Base + Monthly * x[/tex]
[tex]y = 130 + 45 * x[/tex]
[tex]y = 130 + 45x[/tex]

Factorise the following.
Answer:
iii. (p - 7)(p - 3)
iv.(x - 8)(x + 4)
Step-by-step explanation:
iii. p² - 10p + 21
= p² - (7 + 3)p + 21
= p² -7p -3p + 21
= p(p - 7) - 3(p - 7)
= (p - 7)(p - 3)
iv. x² - 4x - 32
= x² - (8 - 4)x - 32
= x² - 8x + 4x - 32
= x(x - 8) + 4(x - 8)
= (x - 8)(x + 4)

The radius of a circular disk is given as 24 cm with a maximum error in measurement of 0.2 cm. (a) Use differentials to estimate the maximum error in the calculated area of the disk. (Round your answer to two decimal places.) cm2 (b) What is the relative error
Answer:
9.60πcm²
Step-by-step explanation:
Area of circular disk, A = πr²
Differntiate A with respect to r
dA/dr = π * (2r^(2-1)) /(2-1) + C
dA/dr = π * 2r/1
dA/dr = 2πr
dA = 2πr * dr
dA = 2πrdr
dA = maximum error ; dr= Error in measurement = 0.2 cm ; r = radius = 24cm
dA = 2π * 24 * 0.2
dA = 9.60πcm²

Answer:
The measure of angle BED is 82°
Step-by-step explanation:
The angles of a triangle, all together, equal 180°.
Angle B and D are the same and angle B is 49° so angle D is also 49°.
You add 49 to 49 which equals 98, and subtract 98 from 180 to find out what angle E is.
