Group of answer choices
The mean is the best measure of center, and it equals 19.
The median is the best measure of center, and it equals 4.
The median is the best measure of center, and it equals 19.
The mean is the best measure of center, and it equals 4.
Here is the graph in image form:
Answer:
I think its the first option.
Step-by-step explanation:
I think Its A because I think the mean is the stretch of a graph like shown in the image which is 19. So, I think that is your answer A.
The outside temperature was -6°C at 8:30 ᴀ.ᴍ. The temperature changed by an average of −0.6°C per hour until 11:00 ᴀ.ᴍ. Complete the sentences to identify the temperature at 11:00 ᴀ.ᴍ. and explain why it is reasonable. Select the correct answer from each drop-down menu. The temperature at 11:00 ᴀ.ᴍ. was
Choose...
. This is reasonable because the temperature
Choose...
each hour, meaning the ending temperature was
Choose...
than the beginning temperature.
Answer:
Step-by-step explanation:
The temperature at 11:00 a.m. was -8.4°C_. This is reasonable because the temperature decreased by -0.6°C each hour, meaning the ending temperature was 1.8°C lower than the beginning temperature.
A store regularly sells a Nintendo Switch Lite for $200. They are currently on sale for 30% off and in your state the sales tax is 8%. What would be the final cost for the consumer (including tax) if they buy the Nintendo Switch Lite?
Answer:
$151.20
Step-by-step explanation:
The sale price of the Nintendo Switch Lite is 30% off its regular price of $200, which means the discount is:
Discount = 30% x $200 = $60
The sale price of the Nintendo Switch Lite after the discount is:
Sale price = $200 - $60 = $140
The sales tax in the state is 8%, so the tax amount on the sale price is:
Tax amount = 8% x $140 = $11.20
Therefore, the final cost for the consumer, including tax, would be:
Final cost = Sale price + Tax amount = $140 + $11.20 = $151.20
Hence, the final cost for the consumer, including tax, would be $151.20 if they buy the Nintendo Switch Lite.
Caden is making beaded necklaces. Blue and red are his favorite colors, so he buys 50 grams of beads in each color. He switches between the two colors, but he runs out of the red beads first. That makes him wonder how much heavier the red beads are than the blue ones. After counting them, he finds he bought 250 blue beads but only 200 red beads. How many milligrams heavier is a red bead than a blue bead?
Since Caden bought 50 grams of each color and all the blue beads weigh the same and all the red beads weigh the same, we can divide 50 by the number of blue beads to find the weight of a single blue bead:
50 grams / 250 beads = 0.2 grams per blue bead
Similarly, we can divide 50 by the number of red beads to find the weight of a single red bead:
50 grams / 200 beads = 0.25 grams per red bead
To find the weight difference between a red bead and a blue bead, we can subtract the weight of a blue bead from the weight of a red bead:
0.25 grams per red bead - 0.2 grams per blue bead = 0.05 grams per bead
To convert grams to milligrams, we can multiply by 1000:
0.05 grams per bead * 1000 = 50 milligrams per bead
Therefore, a red bead is 50 milligrams heavier than a blue bead.

Arjun’s mom is throwing a birthday party for his younger sister! She’s trying to figure out how many cupcakes to order when she realizes that it depends on the number of people eating cupcakes at the party.
What is the independent variable in this scenario? Why?
Answer:
Arjun's mom can vary the number of cupcakes she orders depending on the number of people expected to eat them.

The independent variable in this scenario is the number of people eating cupcakes at the party. It is a variable that can be changed or manipulated and is not affected by other variables. In this case, Arjun's mom can vary the number of cupcakes she orders depending on the number of people expected to eat them.
Clara and her little sister are making kites to fly in the park. Clara ties 60 centimeters of ribbon to the bottom of her little sister's kite. Clara's kite is bigger, so she needs more ribbon than her sister. Clara uses an extra 40 centimeters of ribbon for her own kite. If Clara started with 2 meters of ribbon, how many centimeters does she have left?
Answer:
Clara will have 40 centimeters of ribbon left.
Step-by-step explanation:
1 meter is the same as 100 centimeters, so 2 meters is 200 centimeters. So, we take 200 centimeters, subtract 60 centimeters:
[tex]200 - 60= 140[/tex]
so she has 140 centimeters, then we subtract another 60 centimeters for Clara's kite:
[tex]140 - 60= 80[/tex]
But remember, she needs an extra 40 centimeters because her kite is bigger:
[tex]80 - 40= 40[/tex]
So, Clara is left with 40 centimeters, or 0.4 meters, of ribbon.
