copy machine makes 253 copies in 5 minutrs 45 seconds . How many per minute?
Answer:
46 copies I guess
Step-by-step explanation:
253÷5.45 =46
Correct me if i wrong
Answer:
46.422
Step-by-step explanation:
The answer is 46.422 because it's asking for how many copies per minute. And since we know there are 253 copies, we will divide 253 by 5.45. When you divide those you get 46.422
Find the equation of the line having a slope of 4 and a y-intercept on (0,3)
[tex]\mathbb{FINAL\:ANSWER:}[/tex]
[tex]\huge\boxed{\sf{y=4x+3}}[/tex]
[tex]\mathbb{SOLUTION\:WITH\:STEPS:}[/tex]
Hi! Hope you are having a nice day!
We are given the slope of the line and its y-intercept.
So, let's find the equation.
The y-intercept is written in the form (0, b).
No worries! b is the y-intercept.
Thus, the y-intercept equals 3.
Now, let's find the equation of the line with a slope of 4 and a y-intercept of 3.
We can write the equation in Slope-intercept form:
y=mx+b, where m stands for the slope and b stands for the y-intercept.
Since we have both m and b, we can just plug the given values:
y=4x+3 ✓
Hope you could understand everything.

Rong Huang can buy 4 books with 2/9 of his money. He can buy another 8 such books and 2 identical bags with the rest of his money. How many such bags can he buy with the original sum of money?
Step-by-step explanation:
remember, that a/a = 1, and this is always the "whole" in such fraction scenarios.
in our case here : 9/9 or 3/3.
4 books for 2/9 of his money.
8 books for then 2× 2/9 = 4/9 of his money.
that is together
12 books for 6/9 = 2/3 of his money.
that leaves 3/9 = 1/3 of his money for the 2 identical bags.
so, 1/3 of his money for 2 bags.
how many bags for the whole (3/3) money ?
1/3 × x = 3/3
x = 3
he could have bought 3×2 = 6 bags with the original sum of money.
find the cardinality of x , if x={-n,...,-2,-1,0,1,.....n}
If the scale factor of sides is 3, then the scale factor of area is ___ and the scale factor of
volume is __
Answer:
Here is an example: if we have a rectangle that has a length 3 and a height of 4 and the scale drawing with a scale factor of 2, how many times bigger is the scale drawings area? The original shape is 3 by 4 so we multiply those to find the area of 12 square units.
Answer:
9
27
Step-by-step explanation:
the scale factor of area is 3² = 9
the scale factor of volume is 3³ = 27

Step-by-step explanation:
A local school board wants to determine the proportion of households in the district that would support starting the school year a week earlier. They ask a random sample of 100 households whether they would support starting the school year a week earlier, and 43 households responded that they would. The school board plans to construct a 95% confidence interval for the true proportion of households that would support starting the school year a week earlier. Are the conditions for inference met?
A)Yes, the conditions for inference are met.
B)No, the 10% condition is not met.
C)No, the randomness condition is not met.
D)No, the Large Counts Condition is not met.
The conditions for inference is not met in the question due to the fact that the large count condition is not met.
What is the large count condition in statistics?This is the condition in statistics that states that the numbers of the successes and the failures have to be greater than 10 for there to be a normal distribution.
Using this formula n(1-p) ≥ 10. The probabilioty is 95%, therefore it would be less than 10

why does -2 to the power of 3 produce the same answer as (-2) to the power of 3
Answer:
because it's an odd exponent
Step-by-step explanation:
-2^3 = -(2*2*2)
(-2)^3 = (-2)*(-2)*(-2)
if it was ^4 the sign would be flipped:
-2^4 = -(2*2*2*2) = -16
(-2)^4 = (-2)*(-2)*(-2)*(-2) = 16
The way to put this is that any negative base raised to an odd-numbered power, will result in a negative result, whereas any negative base raised to an even-numbered power, will result in a positive result, with the EXCEPTION of a negative base written WITHOUT grouping symbols. For instanse:
[tex]\displaystyle -1000 = -10^3 \\ -1000 = [-10]^3 \\ \\ BUT \\ \\ 10000 ≠ -10^4\:[-10000 = -10^4] \\ 10000 = [-10]^4[/tex]
I hope you know the differense now, and as always, I am joyous to assist anyone at any time.
100 POINYS AND BRIANLIST
Answer: See below
Step-by-step explanation:
Let A represent an adult who visited a therapist
Let B represent an adult who used a non-prescription antidepressant
Given:
P(A) = 0.28 P
P (B) = 0.43
P(A Intersection B) = 0.22
a) P(B ∩ A) = P (B ∩ A) / P(A) = 0.22/0.27
P(B | A) = 0.79 or 79%
b) P(A ∩ B) = P (A ∩ B) / P(B) = 0.22/0.4.3
P(A | B) = 0.51 or 51%
Answer:
(a) 44.44%
(b) 71.43%
Step-by-step explanation:
Let A = adults who visited a therapist.
Let B = adults who used antidepressants.
Therefore:
P(A) = 0.28P(B) = 0.45P(A ∩ B) = 0.20Part (a)[tex]\boxed{\begin{minipage}{5 cm}\underline{Conditional Probability formula}\\\\A given B:\\\\$\sf P(A|B)=\dfrac{P(A \cap B)}{P(B)}$\\\end{minipage}}[/tex]
To calculate the probability that an adult visited a therapist (Event A) during the past year, given that he or she used antidepressants (Event B), use the conditional probability formula for A given B:
[tex]\implies \sf P(A | B)=\dfrac{PA \cap B)}{P(B)}[/tex]

Need help with Geometry math
problem #9
Answer:
Let ABC be a triangle such that CA is produced to meet at E.
We know, an exterior angle of a Triangle is equal to non- adjacent interior angle, so
8x - 10 = x + 15 + 2x + 20
or, 8x - 3x = 35 + 10
or, 5x = 45
or, x = 9
A rectangular prism has a length of 10 in., a width of 2 in., and a height of 3 1/2 in. The prism is filled with cubes that have edge lengths of 1/2 in.How many cubes are needed to fill the rectangular prism
Solution:
Step-1: Find the volume of the rectangular prism.
Volume of rectangular prism: LBH=> Volume of rectangular prism: (10)(2)(3 1/2)=> Volume of rectangular prism: (10)(2)(3.5)=> Volume of rectangular prism: (2)(35)=> Volume of rectangular prism: 70 in³Step-2: Find the volume of the small cube.
Volume of cube: L³=> Volume of cube: (1/2)³=> Volume of cube: (1³/2³)=> Volume of cube: (1/8)Step-3: Divide.
70 ÷ 1/8 => 70 x 8=> 560 cubesThus, 560 cubes are needed to fill the rectangular prism.

Three consecutive integers have a sum of 57. Find the integers.
Answer:
18, 19, and 20.
Step-by-step explanation:
Consecutive means beside. Numbers 2 and 3 are consecutive integers. Given this question, numbers 6, 8, and 9 could possibly be the answer. However, we don't know this, so let's represent the 6 as x, 7 as x+1. 9 is x+2. We know when these are added together the sum is 57, so 3x+3 should be 57. Now, solve as a normal algebraic question.

AB of the right triangle ABC is twice the length of the leg BC. Find the number of degrees in angle ABC
Answer:
It is 45 degree angle
Step-by-step explanation:
AB is the tilted angle of the triangle
BC is the height and the vertical part of the triangle
If AB is 10 then BC is 5 and AC is possibly about 6-8
If that is so then 2 right triangles is a square
A square has 90 degree angles on any angle
Divide 90 by 2 which is 45 because a right triangle is half of a square
Therefore angle ABC is 45 degrees

You are buying carpet to cover a room that measures 42 ft by 42 ft. The carpet cost $ 25 per square yard. How much will the carpet cost?
Ok so, 42 ft. by 42 ft.
$25 per square yard
1 square yard = 9 square feet
The total square footage is 1,764 ft.
Total square yards is 196.
The total cost would be $4,900.
so basically i just need help on calculating a percentage of a number, for example 30% of 40 and stuff like that. please help asap :')
Answer:
Percentage can be calculated by dividing the value by the total value, and then multiplying the result by 100. The formula used to calculate percentage is: (value/total value)×100%.

Answer:
32 by using triangle taerem
How to do this question
Answer:
b = 5
Step-by-step explanation:
Area of the triangle = b * 12/2 = 6b
Area of the rectangle = 9 * 12 = 108
Total area = 6b + 108 = 138
6b = 138 - 108 = 30
so b = 30/6 = 5

(3-10i)(2+4i)
20 points
Answer:
46 -8i
Step-by-step explanation:
Multiplication of complex numbers is done in a fashion similar to multiplication of any binomials. The difference is that i² = -1, so some terms can be combined.
(3 -10i)(2 +4i) = 3(2 +4i) -10i(2 +4i)
= 6 +12i -20i -40i² = 6 -8i +40
= 46 -8i
