What is length of BC ?
Answer:
BC = 10
Step-by-step explanation:
Since this is an isosceles triangle
AC = BC
3x-5 = 2x
Subtract 3x from each side
3x-5-3x = 2x-3x
-5 = -x
Multiply each side by -1
5 =x
BC = 2x
=2 *5
BC =10
An inspector inspects a shipment of medications to determine the efficacy in terms of the proportion p in the shipment that failed to retain full potency after 60 days of production. Unless there is clear evidence that this proportion is less than 0.05, she will reject the shipment. To reach a decision, she will test the following a large-sample. To do so, she selects an SRS of 200 pills. Suppose that eight of the pills have failed to retain their full potency. The best point estimate for a 95% confidence interval for the true proportion of pills in the shipment that have failed to retain full potency is ___. Round your answer to three decimal places.
Answer:
The sample proportion is p = 0.04.
Step-by-step explanation:
The best point estimate for a 95% confidence interval for the true proportion of pills in the shipment that have failed to retain full potency is ...
Sample of 200 pills.
Eight have failed to retain their full potency.
So the sample proportion is:
[tex]p = \frac{8}{200} = 0.04[/tex]

Suppose that you want to save money and would like to find a savings option that earns you the most
money in interest. You have $1000 to put towards savings. After surveying several banks for savings
plans, you found these options. "A" represents the amount you will have in the bank after x years.
Option A: Your money would receive simple interest at the end of 5 years.
The formula is: A = 1000 + 1000(0.05)x
Option B: Your money will be compounded continuously.
The formula is: A = 1000(2.71828)(0.05x)
Option C: You will invest in a CD (Certificate of Deposit) compounded yearly.
o The formula is: A = 1000(1.05)*
Option D: You buy a US Savings Bond.
The savings bond costs $1000 now. When cashed in 5 years later, the amount will be
$1267. You must leave the money in the savings bond for 5 years to earn any interest.
But, you do not receive any additional interest if you leave it in longer than 5 years.

Please help I have no clue lol
Answer:
x=12
y=44
z=25
Step-by-step explanation:
Since it's an equilateral triangle, all 3 angles have to equal 60.
5x=60
x=12
y+16=60
y=44
3z-15=60
3z=75
z=25
X=8
THE DIRECTIONS ARE ON THE TOP
Answer:
y = 40
Step-by-step explanation:
For #7, we are told that y = 10 when x = 2
We are also told that 'y varies directly as x'. That means there is some constant number, k, so that
Formula --> y = kx
Since y=10 and x= 2, we substitute those numbers into the formula.
We get 10 = k × 2.
So k has to be 5, right?
k = 5
So what is y when x = 8?
Use the formula.
y=kx ---> That gives us y = k × 8. But we know k is 5.
So y = 5 × 8 = 40
y = 40
9514 1404 393
Answer:
7. y = 5x; y = 40
8. y = 1/3x; y = 8/3
Step-by-step explanation:
In the direct proportion equation y=kx, the value of k can be found as ...
k = y/x . . . . . divide both sides by x to solve for k
__
7. k = 10/2 = 5
The equation is ...
y = 5x
For x=8, the value of y is found using the equation:
y = 5(8) = 40
__
8. Same deal, different numbers.
k = 6/18 = 1/3
y = 1/3x . . . . . the equation
y = 8/3 . . . . . y for x=8

Convert to slope intercept form 4x+5y=-20
Answer:
Slope-intercept form is: y=mx+b. Where m = slope or rise/run & b = y-intercept or where the line crosses the y axis. So for 4x + 5y = 20 the slope intercept form is y = -4x/5 + 4.
Step-by-step explanation:
Answer:
y = -4/5x - 4
Step-by-step explanation:
4x + 5y = -20
-4x -4x
5y = -4x - 20
divide it all by 5
y = -4/5x - 4
Hope this helped! Have a nice day! Plz mark as brainliest!!!

g(x) = 5x - 12x2 + 3
The factor of the function will be (4x - 3) and (3x + 1). The graph of the function is shown below.
What is a factorization?It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.
The function is given below.
g(x) = 5x - 12x² + 3
Then the function can be written as
g(x) = - 12x² + 5x + 3
Then the factor of the function will be
g(x) = 0
Then we have
- 12x² + 5x + 3 = 0
12x² - 5x - 3 = 0
12x² - 9x + 4x - 3 = 0
(4x - 3)(3x + 1) = 0
x = -0.33 and 0.75
Then the graph of the equation will be given below.

pls help me answer this !!
We want our exponential function to look like
y = ab^x.
Let a = the initial y-value.
Our initial value is the first number given for f(x). So, a = 3.
Let b = the number that is needed to go from 3 to 6 to 12 to 24 to 48.
We find b by division.
So, b = the next number divided by the previous.
So, b = 6/3 = 2.
We now plug in our values into the general formula above.
y = ab^x
Answer: y = (3)(2)^x

Answer:
x = 10
Step-by-step explanation:
Angles 12x and 10x + 20 are "vertical angles," meaning that they are identical (same value). Therefore we can write the equation 12x = 10x + 20, which reduces to 2x = 20, or x = 10.
Answer:
x=10
Step-by-step explanation:
Hey There!
Those are a pair of vertical angles
Therefore they are congruent
congruent meaning identical in form
So we would setup and equation and because the angles are congruent the equation would be
12x=10x+20 and solve for x
Step 1 subtract 10x from each side
10x-10x cancels out
12x-10x=2x
now we have
2x=20
Step 2 divide each side by 2
2/2 cancels out
20/2=10
Therefore x=10

Answer:
An event can have a probability of 3/2 is not true
Step-by-step explanation:
The probability of an event happening is between 0 and 1 inclusive.
A probability of 1 means the event is certain to happen or 100%
You cannot have a probability greater than 1 so
An event can have a probability of 3/2 cannot happen
What is the slope of a line perpendicular to the line who’s equation is x-y=5 fully reduce your answer
Answer:
-1
Step-by-step explanation:
Use the slope intercept formula(y=mx+b) to find the slope of a line.
First, you will want to put everything into it's proper order, so you will get -y=-x+5.
You cannot have a negative y, so divide everything by -1 and you will get y=x-5.
1 is the slope. Now that you know that, you will want to find the reciprocal. To find the reciprocal, you will need to swap the numerator and the denominator and then swap it's sign, whether that is positive or negative..
The reciprocal of 1 is -1. -1 is the slope of the perpendicular line
