Answer:
Step-by-step explanation:
answer should be 0.39
The probability that the placekicker will make 4 of his next 5 attempts from the 20-yard line is 0.39.
What is the probability?Probability in mathematics is the possibility of an event in time. In simple words how many times does that incident is happening in any given time interval?
Given:
A placekicker for a football team makes field goals 85% of the time when kicking from the 20-yard line.
Assuming that field goal attempts can be considered random events.
P = 0.85
n = 5
Standard deviation = √{5 x 0.85 x (1 - 0.85) = 0.79
The probability that the placekicker will make 4 of his next 5 attempts from the 20-yard line is,
= P (X ≥ 4)
= P (X ≥ 3.5)
= 1 - P(X < 3.5)
= 0.39
Therefore, the probability is 0.39.

A circus audience sits in rows around the performing ring. There are 9 seats in each row. How many rows will need to be set up if 513 people are expected to attend the show?
Answer:
57 rows
Step-by-step explanation:
Since each row will have a total of 9 seats, then we would simply need to divide the total number of individuals that will attend the show by 9 in order to calculate the number of rows that need to be set up around the performing ring.
513 / 9 = 57 rows
Therefore, we can see that we would need a total of 57 rows of 9 chairs each in order for there to be enough chairs to seat 513 people.

Ingrid and Harish were trying to solve the equation:
x^2-3x=x+1
Ingrid said, “First, I'll subtract x from both sides so I have x^2-4x=1. Then I can solve by completing the square. If I add 4 to each side, I can rewrite the equation as (x-2)^2=5. Harish said, “I'll isolate the x^2x term by adding 3x to both sides of the equation. Then I'll solve by taking the square root.”
Whose solution strategy would work?

Help me please please please!
Answer:
X = 12
Step-by-step explanation:
Since each angle is equivalent to each other, you can write the equation:
(9x-3) = (7x+21)
Then Simplify.
Subtract both sides by 7x
2x-3=21
Add 3 To Both Sides
2x=24
Divide by 2
X = 12
Answer:
9x-3=7x+21
9x=7x+24
2x=24
x=12
Step-by-step explanation:
(9x-3) and (7x+21) are corresponding angles that means that they are congruent. So they equal each other.

Note: The triangle next to y and x in the fraction is read: "delta y divided by delta x."
It means the difference of the y terms divided by the difference of the x terms.
Refer to the various selling prices of various homes in a community that follow the normal distribution with mu (population mean) = $276,000 and sigma (standard deviation – measure of dispersion) = $32,000. Calculate the probability that the next house in the community will sell for between $276,000 and $325,000.
Answer:
0.43715
Step-by-step explanation:
We solve using z score calculator
z = (x-μ)/σ, where
x is the raw score
μ is the population mean = $276,000
σ is the population standard deviation = 32,000
For x = $276,000
z = 276,000 - 276,000/32000
z = 0
Probability value from Z-Table:
P(x = 276000) = 0.5
For x = $325,000
z = 325,000 - 276,000/32000
z = 1.53125
Probability value from Z-Table:
P(x = 325000) = 0.93715
The probability that the next house in the community will sell for between $276,000 and $325,000 is
P(x = 325000) - P(x = 276000)
= 0.93715 - 0.5
= 0.43715
Solve 15=3n+6p, for n
Answer:
[tex]n=5-2p[/tex]

[tex]3n+6p=15[/tex]
STEP 2: Subtract 6 p from both sides of the equation.
[tex]3n=15-6p[/tex]
STEP 3: Divide each term by 3 and simplify.
[tex]n=5-2p[/tex]
What is the area of this Parallelogram?
Answer:
Opposite sides are equal in length and opposite angles are equal in measure. To find the area of a parallelogram, multiply the base by the height. The formula is: A = B * H where B is the base, H is the height, and * means multiply.

Find the EXACT value of sec (-120 degrees)
Well sec(-120) = 1/cos(-120).
We know that cos(-120) = -1/2.
So, 1/(-1/2) = -2.
This means that sec(-120) = -2.
the graph of a linear equation in two variables is _____?
Answer:
"a straight line"
Step-by-step explanation:
recall that a linear equation may be expressed as
y = mx + b, where x and y are the variables (i.e 2 variables)
we also know that if we graph the linear equation y = mx+b, we will get a straight line.
Hence a possible answer for the blank could be:
"a straight line"

Johnny has $100 in the bank and plans to deposit $15 per day. Sal has $250
in the bank and plans to withdraw $10 from the bank each day. How many days
until they have the same amount in the bank?
Answer:
6 days
Step-by-step explanation:
First we have to write an expression that represents Johnny's and Sal's banking plans.
Johnny: He has an initial value of $100 and that value will increase by $15 every day. So the expression looks like: 15x + 100, where x is the amount of days it's been.
Sal: An initial value of $250 and the value will decrease by $10 everyday. The expression looks like: -10x + 250, where x is the amount of days it's been.
To find how many days they have until they have the same amount of money in the bank, we can set the expressions equal to each other and solve for x:
15x + 100 = -10x + 250
Add 10x to both sides to isolate the x on one side of the equation:
25x + 100 = 250
Subtract 100 from both sides of the equation to isolate 25x:
25x = 150
Divide both sides by 25 to find the value of x:
x = 6
Since x represents the amount of days it's been, x = 6 means that it will take 6 days for their bank accounts to have the same amount of money in them.
Hope this helps :)
