On a blueprint, a wall that is 45 feet long is 6 inches long. How long should a girder appear on the blueprint if the girder is actually 30 feet long?
Answer:
4 inches
Step-by-step explanation:
1 foot = 12 inches
45 feet --- 6 inches
From this we can conclude that the scale of the Blueprint is:
1 foot in actual = 1/90 foot on blueprint
If the girder is actually 30 feet long, then
30 feet --- (1/90*30*12) inches
30 feet --- 4 inches

a baseball team has 13 players; how many possible batting orders can the coach make if there are 9 players in the batting lineup ?
A. 514,874
B. 235,368
C. 259,459,200
D. 879,523
Final answer:
The number of possible batting orders a coach can make with 13 players for 9 positions is found by calculating [tex]^{13}P_9[/tex], which equals 518,918,400. Thus, the correct answer is C. 259,459,200.
Explanation:
To determine how many possible batting orders a baseball coach can make with 13 players to fill 9 positions, we use the concept of permutations since the order in which the players are arranged matters. The formula for permutations of n items taken r at a time is [tex]^{n}P_r[/tex] = n! / (n - r)!, where the exclamation point indicates a factorial. In this case, we have 13 players and want to find out the number of ways to arrange 9 of them, so we calculate-
[tex]^{13}P_9[/tex]= 13! / (13 - 9)!.
We can simplify this by calculating the factorials: 13! = 13 × 12 × 11 × 10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 and 4! = 4 × 3 × 2 × 1, so [tex]^{13}P_9[/tex] = 13! / 4!.
Instead of multiplying out both factorials completely, we can cancel out the common terms: (13 × 12 × 11 × 10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1) / (4 × 3 × 2 × 1) = (13 × 12 × 11 × 10 × 9 × 8 × 7 × 6 × 5) / 1.
Calculating the above gives us 13 × 12 × 11 × 10 × 9 × 8 × 7 × 6 × 5 = 518,918,400 ways to arrange the batting order. Therefore, the correct answer to how many possible batting orders can be made is C. 259,459,200.

A juice company produces 8,064 cartons of juice in 21 days. Each day, they produced the same number of cartons and delivered those cartons to 16 area coffee shops. The cartons were delivered in cases of six cartons per case, and each coffee shop received an equal number of cases in each delivery. How many cases were delivered to each coffee shop each day?
Answer:
[tex]4\ cases[/tex]
Step-by-step explanation:
Step 1
Divide the total cartons of juice that the company produces in [tex]21[/tex] days by the total days
so
[tex]\frac{8,064}{21}\frac{cartons}{days}=384\frac{cartons}{day}[/tex]
Step 2
Divide the total cartons of juice that the company produces in one day by the total coffee shops
so
[tex]\frac{384}{16}\frac{cartons}{coffee-shop}=24\frac{cartons}{coffee-shop}[/tex]
Step 3
Divide the total cartons of juice that the company delivered per day to each coffee shop by six (number of cartons per case)
so
[tex]\frac{24}{6}=4\ cases[/tex]

Use synthetic division to solve (x^3-x^2-17x-15)/(x-5)
Answer: [tex]1x^2+4x+3[/tex]
Step-by-step explanation: Given expression (x^3-x^2-17x-15)/(x-5).
We need to divide it x^3-x^2-17x-15 by x-5 using synthetic division .
In order to solve by synthetic division, we would write all the coefficients of given divisor polynomial:
And we divide them by 5 using synthetic division method.

Data were collected on monthly sales revenues (in $1000s) and monthly advertising expenditures ($100s) for a sample of drug stores. the regression line relating revenues (y) to advertising expenditure (x) is estimated to be modifyingabove y with caret equals negative 48.3 plus 9.00 xy=−48.3+9.00x. what is the interpretation of the slope?
Answer:
The interpretation of the slope is that for each $1000 you spend, your revenue increases by $900.
Step-by-step explanation:
We have that:
The revenue y is a function of the advertising expediture x, and the relationship is given by the following function:
y = -48.3 + 9x.
However, since y is in thousands and x in hundreds, i am going to rewrite
y = -48.3 + 0.9x
This means that if you spend no money in advertising, you lose -48.3 thousands of dollars. However, for each $1000 you spend, your revenue increases by $900.
So the interpretation of the slope is that for each $1000 you spend, your revenue increases by $900.
You randomly select one card from a standard deck. event a is selecting a fivea five. determine the number of outcomes in event
a. then decide whether the event is a simple event or not.
In a standard deck of cards, there are a total number of 52 different card. From those 52 cards, 4 cards are numbered as five. Therefore the probability of selecting a card of five is:
Probability = 4 / 52 = 1 / 13
Assuming that no replacement is made, so the probability changes with each draw, since the total number of cards decreases from 52 to 51 to 50 and so on. Therefore this is not a simple event.
Raquel throws darts at a coordinate grid centered at the origin. Her goal is to create a line of darts. Her darts actually hit the coordinate grid at (–5, 0), (1, –3), (4, 5), (–8, –6), (0, 2), and (9, 6). Which equation best approximates the line of best fit of the darts? y = 0.6x + 0.6 y = 0.1x + 0.8 y = 0.8x + 0.1 y = 0.5x + 0.6
Solution:
The points at which Raquel Darts hit the coordinate grid having center at the origin are (–5, 0), (1, –3), (4, 5), (–8, –6), (0, 2), and (9, 6).
As we can see that not all points are collinear.
As line of best fit is the the line which passes through some points , may be not through the single point, or all the points.
Plotting all the options on coordinate grid i.e on a scatter plot and then determining , the line of best fit of the darts is
y= 0.6 x + 0.6 →→Option (A), the reason being it passes through a point (9,6).
Use the distributive property to create an equivalent expression to 54+18x
Answer:
An equivalent expression to 54+18x, using the distributive property is 18(3+x)
Step-by-step explanation:
In the problem we have the binomial (54+18x), and we are asked to use the distributive property, this means that we can find a factor wich is distributed in both terms of the binomial.
We know that any number, or in this case any polinomial (or binomial), can be multiplied times 1 and will stay the same number, and we only need to write this 1 in a way that could resolve our problem, in particular we can say that
[tex]1=\frac{18}{18}[/tex]
then we can distribute the denominator, so we calculate:
[tex](54+18x)=1(54+18x)=\frac{18}{18}(54+18x)=18(\frac{54}{18}+\frac{18x}{18})=18(3+x)[/tex]
And the equivalent expression to (54+18x) is 18(3+x).

78 million converted in scientific notation
The correct answer is:
7.8 × 10⁷
Explanation:
To write a number in scientific notation, we want the decimal behind the first non-zero digit in the number. The first non-zero digit in 78 is 7; this means we want 7.8. In order to have the decimal point behind the 7, we need to move the decimal 7 places. This is the exponent of 10 in our scientific notation, which gives us
7.8 × 10⁷

A line passes through the points (–1, –5) and (4, 5). The point (a, 1) is also on the line.
The value of "a" is 2.
To find the value of "a," we can use the formula for the equation of a line, which is y = mx + b.
First, we need to find the slope, represented by "m," using the given points (-1, -5) and (4, 5). The slope formula is (y2 - y1) / (x2 - x1).
Substituting the coordinates, we have:
m = (5 - (-5)) / (4 - (-1))
m = 10 / 5
m = 2
Now that we have the slope, we can substitute it into the equation of the line with the point (a, 1):
1 = 2a + b
To solve for "a," we need to find the value of "b." We can substitute one of the given points into the equation and solve for "b."
Using (-1, -5):
-5 = 2(-1) + b
-5 = -2 + b
b = -3
Now we can substitute the values of "b" and "a" into the equation:
1 = 2a - 3
To isolate "a," we add 3 to both sides:
1 + 3 = 2a
4 = 2a
Dividing both sides by 2, we find:
2 = a
Therefore, the value of "a" is 2.

The sampling distribution of the proportion follows the normal distribution when the values np and nq are greater than or equal to
The sampling distribution of the proportion follows the normal distribution when the values np and nq are greater than or equal to 5.
Explanation:For the sampling distribution of the proportion to follow a normal distribution, the values np and nq must both be greater than or equal to 5.
For example, if you are performing a hypothesis test of a single population proportion, the conditions np >= 5 and nq >= 5 must be met to approximate the binomial distribution by the normal distribution.
Remember that np represents the number of successes in the sample and nq represents the number of failures in the sample.
