Supervisor: "you took 500 calls in 30 days." representative: "that means i took an average of __________ calls per day. i'm pretty pleased with that."
Answer:
an average of around 16 calls per day
Step-by-step explanation:
Simply divide 500 by 30 and that comes out to 16.66666
But because you cannot take half a call you just use 16 as your answer!

Step-by-step explanation:
the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ 4 , ∠ 5 , ∠ 6 are exterior angles of the triangle
-------------------------------------------
(14)
∠ 1 and ∠ 4 are adjacent angles and sum to 180° , then
∠ 1 = 180° - 58° = 122°
∠ 2 + ∠ 3 = ∠ 4
∠ 2 + 32° = 58° ( subtract 32° from both sides )
∠ 2 = 26°
∠ 5 = ∠ 1 + ∠ 3 = 122° + 32° = 154°
∠ 6 = ∠ 1 + ∠ 2 = 122° + 26° = 148°
(15)
∠ 4 = ∠ 2 + ∠ 3 = 11° + 143° = 154°
∠ 1 = 180° - ∠ 4 = 180° - 154° = 26°
∠ 5 = ∠ 1 + ∠ 3 = 26° + 143° = 169°
∠ 6 = ∠ 1 + ∠ 2 = 26° + 11° = 37°

Lucy is designing a new board game, and is trying to figure out all the possible outcomes. How many different possible outcomes are there if she rolls a fair die in the shape of a pyramid that has four sides labeled 1 to 4, spins a spinner with 5 equal-sized sections labeled Monday, Tuesday, Wednesday, Thursday, Friday, and spins a spinner with four equal-sized sections labeled Red, Green, Blue, Orange?
The total possible outcomes are there if she rolls a fair die in the shape of a pyramid that has four sides labeled 1 to 4, spins a spinner with 5 equal-sized sections is 20.
What is permutation and combination?A permutation can be defined as the number of ways a set can be arranged, order matters but in combination the order does not matter.
We have:
Total number of outcomes for pyramid = 4
Total number of outcomes for spinner = 5
Total outcomes = 4×5 (multiplication rule of counting)
= 20
Thus, the total possible outcomes are there if she rolls a fair die in the shape of a pyramid that has four sides labeled 1 to 4, spins a spinner with 5 equal-sized sections is 20.

Answer:
V = 162 ft³
Step-by-step explanation:
given 2 similar figures with ratio of sides a : b , then
ratio of volumes is a³ : b³
here ratio of sides = 3 : 1 , then
ratio of volumes = 3³ : 1³ = 27 : 1
this means that the volume of figure A is 27 times the volume of figure B
volume (V) of figure A is then
V = 27 × 6 = 162 ft³
What is the probability that the average of four babies' weights will be within 1. 2 pounds of the mean; will be between 6. 8 and 9. 2 pounds?
The probability that the average of four babies' weights will be within 1. 2 pounds of the mean; will be between 6. 8 and 9. 2 pounds is 0.74.
What is the probability?Probability is the branch of mathematics, which discusses the occurrence of a random experiment.
The average of four babies' weights will be within 1. 2 pounds of the mean; will be between 6. 8 and 9. 2 pounds.
The standard error of the sample will be:

The probability that the average of four babies P(4 babies will be between 8.4 - 9.6 pounds) is;
[tex]\rm P(6.8\leq X\leq 9.2)= \left( \dfrac{6.8-8}{0.6}\leq X\leq \dfrac{9.2-8}{0.6} \right )\\\\\rm P(6.8\leq X\leq 9.2)= \left( \dfrac{-1.2}{0.6}\leq X\leq \dfrac{1.2}{0.6} \right )\\\\\rm P(6.8\leq X\leq 9.2)= \left( -2\leq X\leq 2 \right )\\\\\rm P(6.8\leq X\leq 9.2)= P(Z\leq -2)-P(Z\leq 2)\\\\ P(6.8\leq X\leq 9.2)=0.97-0.22\\\\ P(6.8\leq X\leq 9.2)=0.74[/tex]

Determine the approximate ordered pair for f(x) = g(x).
There is a screenshot that I have attached and here are the options that you can answer:
(3, 12)
(3, 18)
(12, 3)
(18, 3)
The approximate ordered pair is the coordinate where both functions graph intercect
That's can be found only by observing graph.
As we observe we find that
The coordinate at where f(x)=g(x) is (3,18)
It means that
at this the values of both the functions are equal
i.e
f(3)=g(3)=18Answer:
b) (3, 18)
Step-by-step explanation:
f(x) = g(x) at the point where the two lines intersect.
From inspection of the graph, we can see that the x-value of the point of intersection is between 0 and 10. Therefore, from the options given, it must be x = 3 (since 12 > 10 and 18 > 10).
From inspection of the graph, we can see that the y-value of the point of intersection is between 10 and 20, but it's nearest to 20 than it is 10. Therefore, from the options given, it must be y = 18.
Therefore, the approximate ordered pair is (3, 18)

Answer:
B. 5/8
Step-by-step explanation:
To find this you will want to find what the 2 denominators have in common. In this instance if you multiply 4 by 2 you will get 8. Once you find what you can do to get the same denominators you will multiply the numerator with the same number as the denominator. So 4x2 and 1x2 gives us 2/8 as our new fraction. After this adding fractions is much simplier. It's as simple as adding the numerators together and keeping the denominator as the same. 3/8 + 2/8 = 5/8.

what is 73 divided by 8 equal in remainder???
Answer:
9 remainder 1
Step-by-step explanation:
Not sure but uh... 73/8=9 remainder 1.
Is this what you are looking for?
73 divided by 8 equals 9 with a remainder of 1.
To find the quotient and remainder when dividing 73 by 8, we perform long division.
Here's how it works:
We start by dividing the first digit of the dividend (7) by the divisor (8). Since 7 is smaller than 8, the quotient will be 0, and the remainder will be 7.
We bring down the next digit from the dividend, which is 3, making the new number 73.
Now, we divide 73 by 8. The largest multiple of 8 that fits into 73 is 9 (8 times 9 equals 72). So, the quotient becomes 9.
We subtract 72 (8 times 9) from 73, resulting in a remainder of 1.
Therefore, 73 divided by 8 equals 9 with a remainder of 1.

Answer:
A) f(x) = |x|
B) f(x) = -|x+3| + 3
Step-by-step explanation:
Absolute value functions
The general form of an absolute value function is f(x) = a|x-b| +c
a indicates the 'amplitude' or multiplier
b indicates horizontal shift
c indicates vertical shift
The turning point of f(x) = |x| is (0, 0)
a = y/x when b = 0 and c = 0
A) f(x) = |x|
Since the turning point is still (0, 0) there is no horizontal nor vertical shift, meaning b = 0 and c = 0
We have the point (2, 2), thus a = 2/2 = 1
f(x) = a|x-b| + c
f(x) = |x|
B) f(x) = -|x+3| + 3
The turning point is at (-3, 3) b = -3 and c = +3
We have the point (3, -3), thus a = y/x = -3/3 = -1
f(x) = a|x-b| + c
f(x) = (-1) (|x-(-3)|) + (+3)
f(x) = -|x+3| + 3
