Answer:
D. $1,136.79
Step-by-step explanation:
In this example, we want to learn what the original price of the computer would be if the price is $1,205, and this includes a 6% sales tax. This means that this price is 106% of the original price (100% is the price, while 6% is the tax). Therefore:
1205 * 1.06 = 1136.79
Answer:
87
Step-by-step explanation:
A negative times a negative always equals a positive, and 10 times anything is just moving the decimal point to the right once, so 8.7 becomes 87.0
Answer: B
Step-by-step explanation:
(f/g) means to divide f(x) by g(x).
To find the domain, you set the domain equal to zero and solve for x.
3x-5=0 [add both sides by 5]
3x=5 [divide both sides by 3]
x=5/3
Now, we know that B is the correct answer.
The interquartile range (IQR) is 15.
To find the IQR, you must:
1) Find the median
2) Split the data set in two at the median.
3) Find the medians from both the groups you made in Step 2
4) Label the smaller one Quartile 1 and the larger one Quartile 3 (Hint: The median is Quartile 2)
5) Subtract: Quartile 3 - Quartile 1
Number of dog food packages bought by Byron is 300
Step-by-step explanation:
- Step 1: Given number of bird food packages = b. Find the number of packages for the other animal foods.
Number of hamster food packages = b.
Number of dog food packages = 4b
Number of cat food packages = 1/2 of 4b = 2b
Total food packages = 600
⇒ b + b + 4b + 2b = 600
⇒ 8b = 600
⇒ b = 600/8 = 75
- Step 2: Calculate the amount of dog food
∴ 4b = 4 × 75 = 300
