Answer:
= -1/2
Step-by-step explanation:
We can use the slope formula
m = (y2-y1)/(x2-x1)
= (11-10)/(8-10)
= 1/-2
= -1/2
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]

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.

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.

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]

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.

Written in terms of pi how many times greater is the area than the circumference
Answer:
If its radius is 9 cm, it’s circumference would be two times radius times pi equal to 18 pi. Also its area is pi R squared which is equal to 81 pi. Circumference = 18 pi Area = 81 pi Area is 4.5 times greater than the circumference. The answer is C.
Answer:
Those two quantities are incommensurate, you can't compare them. The circumference is a length and the area is an area. There is no way to compare the two.
Now if you're talking about the formula Area = circumference squared over 4 times Pi, and if you're just going to go with the numerical values of Area and circumference, then there is an answer.

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)

Gina buys a car for $13,500. The value is expected to depreciate by 15% per year.
Write an exponential function to model the value of the car. When will the value
fall below $3000?
Answer:
the value will fall below $3000 in the 7 th year because :
Step-by-step explanation:
15% of 13500 is 2025
On subtracting 2025 from 13500 every time we can see that the value keeps dropping.
So, we will get $3375 in year 6 and in year 7 we will get $1350 by subtracting 2025 from 3375.
Hence we will get 1350 at the 7th year.
After 6.79 years, the car's value will drop below $3,000.
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
To Calculate the percent of a number , divide the number by whole number and multiply by 100.
Now, The following is a representation of the exponential function to model the car's value:
V(t) = 13500 (1 - 0.15)ⁿ
V(t) = 13500(0.85)ⁿ
Here, V(t) denotes the car's worth at time n in years, and 0.85 denotes the annual depreciation rate of 15%.
Hence, The following equation can be put up to determine when the car's value will drop below $3,000:
13500(0.85)ⁿ = 3000
As we solve for n, we obtain:
n = (log(3000/13500)/log(0.85))
n = 6.79
So, after roughly 6.79 years, the car's value will drop below $3,000.

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

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]

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]

A consulting firm has bid on two projects, A and B. The probability of landing A is 0.70. The probability of landing B is 0.60. The probability of landing both is 0.50.
What is the probability of landing A given it lands B?
Given:
The probability of landing A is 0.70.
The probability of landing B is 0.60.
The probability of landing both is 0.50.
To find:
The probability of landing A given it lands B.
Solution:
We have,
[tex]P(A) = 0.70[/tex]
[tex]P(B) = 0.60[/tex]
[tex]P(A\cap B) = 0.50[/tex]
The probability of landing A given it lands B is
[tex]P\left(\dfrac{A}{B}\right)=\dfrac{P(A\cap B)}{P(B)}[/tex]
[tex]P\left(\dfrac{A}{B}\right)=\dfrac{0.50}{0.60}[/tex]
[tex]P\left(\dfrac{A}{B}\right)=\dfrac{5}{6}[/tex]
[tex]P\left(\dfrac{A}{B}\right)=0.8333...[/tex]
[tex]P\left(\dfrac{A}{B}\right)\approx 0.83[/tex]
Therefore, the probability of landing A given it lands B is about 0.83.
