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

Answer:
d) 127,000 members
Step-by-step explanation:
A = Accrued Amount (principal + interest)
P = Principal Amount of members = 23,000 initial members
r = Annual Nominal Interest Rate as a decimal = .05
t = years left to increase (2020-1985 = ) 35 years
n = number of times amount compounds per time = 1 time/year
23,000 initial members( 1 + .05/1)^1*35
23,000*(1.05)^35 = 23,000*(5.516) = 126, 868 = around 127,000 members

Which expression represents the surface area?
Answer:
2x + 1/2 sq. ft
Step-by-step explanation:
Surface area = 2(lw+wh+lh)
Given
length l = x ft
width w = 1/2 ft
height h = 1/2ft
Substitute
Surface area = 2(x(1/2)+(1/2)(1/2)+x(1/2))
Surface area = 2(x/2+1/4+x/2)
Surface area = 2(2x/2 + 1/4)
Surface area = 2(x + 1/4)
Surface area = 2x + 2/4
Surface area = 2x + 1/2 sq. ft

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

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.

What is the volume of the container?
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.

the head of a nail is circular , as shown the head of this nail has a diameter of 6 millimeters what measurment is closet to the area
Answer:
Area of nail's head = 28.26 millimeter² (Approx.)
Step-by-step explanation:
Given:
Head of nail is circular
Diameter of nail's head = 6 millimeter
Find:
Area of nail's head
Computation:
Radius of nail's head = Diameter / 2
Radius of nail's head = 6 / 2
Radius of nail's head = 3 millimeter
Area of circle = πr²
Area of nail's head = πr²
Area of nail's head = (22/7)(3)²
Area of nail's head = (22/7)(9)
Area of nail's head = (3.14)(9)
Area of nail's head = 28.26 millimeter² (Approx.)

3(2p+5)-4p+3(5-1)
Answer:
2p+27
Step-by-step explanation:
6p+15-4p+15-3
2p+27
Answer:
2p+27
Step-by-step explanation:
3(2p+5) - 4p + 3(5-1)
so now we expand the brackets...
so we have
6p + 15 - 4p + 15 - 3
and now we group like terms....
so
6p + 4p + 15 + 15 - 3
and now we do the addition and subtraction
so our final answer is
2p + 27
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
In an effort to make children’s toys safer and more tamperproof, toy packaging has become cumbersome for parents to remove in many cases. Accordingly, the director of marketing at Toys4Tots, a large toy manufacturer, wants to evaluate the effectiveness of a new packaging design that engineers claim will reduce customer complaints by more than 10 percentage points. Customer satisfaction surveys were sent to 220 parents who registered toys packaged under the old design and 220 parents who registered toys packaged under the new design. Of these, 81 parents expressed dissatisfaction with packaging of the old design, and 41 parents expressed dissatisfaction with packaging of the new design.

A company produces chairs. The weekly production follow normal
distribution with mean 200 and standard deviation 0 = 16.
Recently new production methods have been introduced. The
maneger would like to know if there has been a change in the
weekly production A sample of 50 chairs is selected. The sample
mean is 203.5 Test using 0.01 significance level.
Answer:
The calculated value Z = 1.548 < 2.326 at 0.01 level of significance
The Null Hypothesis is accepted
There is no change in the weekly production
Step-by-step explanation:
Step(i):-
Given that the mean Population(μ) = 200
Given that the standard deviation of the Population(σ) =16
Given that the mean of the sample (x⁻) = 203.5
Given that the size of the sample(n) = 50
Level of significance = 0.01
Critical value Z₀.₀₁ = 2.326
Null hypothesis : (μ) = 200
Alternative Hypothesis : (μ) ≠200
Step(ii):-
Let 'X' be a random variable in a normal distribution
Test statistic
[tex]Z = \frac{x^{-} -mean}{\frac{S.D}{\sqrt{n} } }[/tex]
[tex]Z = \frac{203.5 -200}{\frac{16}{\sqrt{50} } }[/tex]
Z = 1.548
The calculated value Z = 1.548 < 2.326 at 0.01 level of significance
The Null Hypothesis is accepted
Final answer:-
There is no change in the weekly production
