Point P is plotted on the coordinate grid. If point S is 12 units to the left of point P, what are the coordinates of point S? 10 NAG -12-10-864 -20 32 2 4 6 8 10 12 TP -6 -S 10 - 12 (6.-16) (-6.-16) o(-6,-4) (6,4)
Answer:
(-6, -4)
Step-by-step explanation:
Original coordinates: (6, -4)
POINT S IS 12 UNITS TO THE LEFT OF POINT P.
There are multiple ways to solve this, but I will explain the easiest way.
We can subtract 12 from the x-coordinate.
This because the x-axis runs RIGHT and LEFT.
The y-axis runs UP and DOWN.
6 - 12 = -6
The y-coordinate stays the same.
The new coordinates are: (-6, -4).

Amy knits 1/10 of a scarf in 4/5 of an hour. What fraction of scarf can Amy knit in 1 hour
Answer:
Amy can knit [tex]\frac{1}{8}[/tex] of a scarf in 1 hour.
Step-by-step explanation:
This question can be solved by proportions, using a rule of three.
We have that:
1/10 of a scarf - 4/5 of an hour
x of a scarf - 1 hours.
Applying cross multiplication:
[tex]\frac{4x}{5} = \frac{1}{10}[/tex]
[tex]x = \frac{5}{10*4} = \frac{5}{40} = \frac{1}{8}[/tex]
Amy can knit [tex]\frac{1}{8}[/tex] of a scarf in 1 hour.

A sample of restaurants in a city shows that the average cost of an appetizer is $6.32 with a standard deviation of $0.47. A brand new restaurant wants to get noticed by offering appetizers for a much lower price. To determine the lower price, should the formula use a z-value that is greater than or less than -1?
a.
Greater than -1
c.
Greater than 1
b.
Less than -1
d.
Either way, it doesn’t matter
Answer:
D
Step-by-step explanation:
Is the corrext answer hope it helps
By using a z-value less than -1, we can find a price that is significantly lower than the average cost, and therefore more likely to attract customers.
Option B is the correct answer.
What is a standard deviation?Standard deviation is a measure of the amount of variability or spread in a set of data.
It is calculated as the square root of the variance and is often denoted by the symbol σ (sigma) for a population and s for a sample.
We have,
The z-value formula is used to determine the number of standard deviations a data point is from the mean.
To determine the lower price of appetizers, we want to find a price that is significantly lower than the average cost.
Since the new restaurant wants to offer appetizers for a much lower price, we should use a z-value that is less than -1, which indicates a price that is more than one standard deviation below the mean.
Recall that the z-value formula is:
z = (x - μ) / σ
where x is the value of interest, μ is the mean, and σ is the standard deviation.
Thus,
By using a z-value less than -1, we can find a price that is significantly lower than the average cost, and therefore more likely to attract customers.

To convert a distance of 13,000 feet to miles, which ratio could you multiply
by?
Answer:
2.46212121 miles
-
convert a mile measurement to a foot measurement, multiply the length by the conversion ratio. The length in feet is equal to the miles multiplied by 5,280
The mile, sometimes the international mile to distinguish it from other miles, is the British imperial unit and the US customary unit, both systems are based on the older English unit of length equal to 5,280 feet, or 1,760 yards, and standardised as exactly 1,609.344 metres by international agreement in 1959
To convert 13,000 feet to miles, you can multiply it by the ratio of 1 mile / 5,280 feet.
To convert a distance of 13,000 feet to miles, you can multiply it by the conversion factor of 1 mile divided by 5,280 feet.
We know that
1 mile= 5280 feet
Then we will use the ratio of 1 mile / 5,280 feet, the numerator 1 represents the equivalent distance in miles, and the denominator 5,280 represents the equivalent distance in feet.
So, 13000 feet x 1 mile/ 5280 feet
= 13000/ 5280
= 2.462121212121212 miles
Therefore, to convert 13,000 feet to miles, you can multiply it by the ratio of 1 mile / 5,280 feet.

How many 3 digit numbers can you make using these numbers: 4,2,9 (numbers can be reapeated)
Answer:
You can make 27 different 3 digit numbers
Step-by-step explanation:
Since we can use 3 different numbers this means that each of the 3 digits can be one of the 3 numbers (4,2,9). This means that there are 3 different values for the first digit, 3 different values for the second digit, and 3 different values for the third digit, which mean that we can make 3 x 3 x 3 different 3 digit numbers (we took the number of possible values for each digit and multiplied them together.

Step-by-step explanation:
7- The volume of a rectangular pyramid is:
V=(l x w x h) / 3We just have to substitute the values:
V= 13×12×15 / 3V= 780 m8- The volume of a cone is:
V=hπr² / 3Let's substitute the values and solve:
24×π×19.4² / 39,458.9If you want to round it, the answer will be:
9,459 cm9- The volume of a square pyramid V = a²h / 3, where a is the base and h the height.
So,
V= 12²×18 / 3864 cm10- The volume of the cone is V = hπr² / 3
Then,
V= 16×9×π / 39 is the diameter, which is the radius two times. As you see, what the formula asks is for the radius at the second power -multiplied by itself two times-, but if we get the diameter value instead, there is no need to multiply it. The diameter stays the same.
V= 150.7If you want to round it to the nearest tenth, the answer is:
151 in.Hope this helps!!
