blank minus 1/2 equls to 3/4
Answer:
5/4
Step-by-step explanation:
We can start but setting the blank as x.
x - 1/2 = 3/4
we can put a common denominator on both of the.
2, 4
4, 8
4 is a common denominator.
1/2 times 2/2 = 2/4
x - 2/4 = 3/4
add on both sides.
x = 5/4
Answer:
5/4
Step-by-step explanation:
____ - 1/2= 3/4
____= 3/4+1/2
= 3+2/4 ( LCM of 2,4 is 4)
5/4
Check
5/4-1/2=3/4

What value is an x worth
Answer:
The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol.

4. Assume that the chances of a basketball player hitting a 3-pointer shot is 0.4 and the probability of hitting a free-throw is 0.65. Assume that in a given game the player shoots 10 free throws and 10 3-point shots. Treat each shot is an independent trial and calculate the probability that the player will make exactly 3 3-pointers and 5-free throws.
Answer:
0.0334 = 3.34% probability that the player will make exactly 3 3-pointers and 5-free throws.
Step-by-step explanation:
For each 3-pointer shot, there are only two possible outcomes. Either the player makes it, or the player does not. The same is valid for free throws. This means that both the number of 3-pointers and free throws made are given by binomial distributions.
Since 3-pointers and free throws are independent, first we find the probability of making exactly 3 3-pointers out of 10, then the probability of making exactly 5 free throws out of 10, and then the probability that the player will make exactly 3 3-pointers and 5-free throws is the multiplication of these probabilities.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
Probability of making 3 3-pointers out of 10:
The chances of a basketball player hitting a 3-pointer shot is 0.4, which means that [tex]p = 0.4[/tex]. So this is [tex]P(X = 3)[/tex] when [tex]n = 10[/tex].
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 3) = C_{10,3}.(0.4)^{3}.(0.6)^{7} = 0.21499[/tex]
Probability of making 5 free throws out of 10:
The probability of hitting a free-throw is 0.65, which means that [tex]p = 0.65[/tex]. The probability is [tex]P(X = 5)[/tex] when [tex]n = 10[/tex].
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 3) = C_{10,5}.(0.65)^{5}.(0.35)^{5} = 0.15357[/tex]
Calculate the probability that the player will make exactly 3 3-pointers and 5-free throws.
0.21499*0.15537 = 0.0334
0.0334 = 3.34% probability that the player will make exactly 3 3-pointers and 5-free throws.

If the radius of the base of the cone, r, is 8/3 units and the height, h, is 13 units, what is the volume of the cone?
Answer:
Step-by-step explanation:
r = 8/3 units
h = 13 units
Volume of cone = (1/3) πr²h
[tex]= \frac{1}{3}* 3.14 * \frac{8}{3}* \frac{8}{3}*13\\\\= 96.76 cubic units[/tex]
If the radius of the base of the cone, r, is [tex] \frac{8}{3} [/tex] units and the height, h, is 13 units, what is the volume of the cone ?
Answer:-Given:-[tex] \bullet [/tex] Radius of the base of the cone (r) is [tex] \frac{8}{3} [/tex] units.
[tex] \bullet [/tex] Height (h) of the cone is 13 units.
To Find:-Volume of the cone.
Solution:-We know,
Formula of volume of cone is [tex] \frac{1}{3} [/tex] πr²h
So, volume of the cone = [tex] \frac{1}{3} [/tex] × [tex] \frac{22}{7} [/tex] × [tex] (\frac{8}{3})² [/tex] × 13
= [tex] \frac{1}{3} [/tex] × [tex] \frac{22}{7} [/tex] × [tex] \frac{8}{3} [/tex] × [tex] \frac{8}{3} [/tex] × 13
= [tex] \frac{22 \: × \: 8 \: × \: 8 \: × \: 13}{3 \: × \: 7 \: × \: 3 \: × \: 3} [/tex]
= [tex] \frac{18304}{189} [/tex]
= 96.85 cubic units.
Volume of the cone is 96.85 cubic units. [Answer]which fraction would complete the pattern? 1/4, 2/8, ___, 4/12
Find f(-9) when f(x) = |x|- 6.
Answer: f(x) = 3
Step-by-step explanation:
f(x) = |-9| - 6
f(x) = 9 - 6
f(x) = 3
Answer:
3
Step-by-step explanation:
F(x)= f(-9) meaning x is -9.
When -9 is in absolute value is negative it turns into positive because anytime it it absolute it will turn any number postitive. so the equation turns into 9-6=f(x) which is 3.

Ten less than 5 times the value of a number is equal to 10 times the quantity of
12 more than one-fourth of the number. If a is the number, what is the value of a?
Answer:
The value of a is 52.
Step-by-step explanation:
Ten less than 5 times the value of a number
5a - 10
is equal to 10 times the quantity of 12 more than one-fourth of the number.
This means that:
[tex]5a - 10 = 10(12 + \frac{a}{4})[/tex]
If a is the number, what is the value of a?
Solving the equation:
[tex]5a - 10 = 120 + 2.5a[/tex]
[tex]2.5a = 130[/tex]
[tex]a = \frac{130}{2.5}[/tex]
[tex]a = 52[/tex]
The value of a is 52.

The line L: 4x - 5y + 20 = 0 cuts the x - axis at A and cuts the y - axis at B. find the equation of a line perpendicular to L and passing through the origin.

Answer:
x-intercept: (-5, 0)y-intercept: (0, 4)perpendicular: 5x +4y = 0Step-by-step explanation:
Each of the intercepts is found by setting the other variable to zero and solving for the intercept value.
x-intercept
4x -5·0 +20 = 0
x +20/4 = 0 . . . . . divide by the coefficient of x
x = -5 . . . . . . . . . . add -5
The x-intercept point is (-5, 0).
__
y-intercept
4·0 -5y +20 = 0
y +20/-5 = 0 . . . . . divide by the coefficient of y
y = 4 . . . . . . . . . . . add 4
The y-intercept point is (0, 4).
__
The perpendicular line is found by swapping the x- and y-coefficients, negating one of them. You want the leading coefficient positive, so the equation becomes ...
5x +4y = (some constant)
The constant is chosen according to the point you want on the line. For a line through the origin, the constant is zero.
5x +4y = 0 . . . . perpendicular line
Landon has a points card for a movie theater. He receives 70 rewards points just for signing up. He earns 5.5 points for each visit to the movie theater. He needs 125 points for a free movie ticket. How many visits must Landon make to earn a free movie ticket?
Answer:
10 times
Step-by-step explanation:
125-70 bonus points =55 points left.
55 divided by 5.5 per visit = 10 times to get a free movie ticket.
To verify it is correct:
10 visits x 5.5 points each = 55 points total
55 + 70 bonus points = 125 for a free ticket.
Answer:
10
Step-by-step explanation:
Let x= number of visits
5.5x+70=
125
subtract -70 from 70 and 125
5.5x= 55
divide both sides by 5.5
x=10
