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

Step-by-step explanation:
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

Step-by-step explanation:
A circle circumscribed over a right triangle is the same as a circle circumscribed over a rectangle built from the extension of the right triangle.
That tells us that the hypotenuse is the diameter of the circle in that case.
Here, we can see a triangle that has the hypotenuse as the diameter of the circumscribed circle. We can infer that the triangle is a right triangle.

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.

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.)

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

The boxplot required to answer the question has been attached below
Answer:
E
Step-by-step explanation:
The maximum value on a box plot can be obtained by taking the value at the end of the whisker positioned to the right of the box in the boxplot. From the boxplotvgiven above, the maximum value provided by the endpoint of the right hand side whisker is 48. The 48 point mark is labeled as E in the plot.
Hence, the letter depicting the maximum value position on the box plot is the letter E
All corners are right angles.

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
