4
1
2
412
pounds and less than
6
pounds?
Enter your answer in the box.
_____fruit baskets
Answer:
8.
Step-by-step explanation:
5 and 5 1/2 are the only fractions between 4 and 6. There are 4 dots above each, and 4 x 2 = 8. (I know the amount of dots because I had this question.)
There are two baskets that weigh more than 4 but less than 6.
The weights of fruit baskets are:
4, 1, 2, 5, 5(1/2), 6
What is weight?Weight is the quantity of matter in a physical body.
We can see that fruit baskets that weigh more than 4 pounds but less than 6 pounds are ones with weights of 5 pounds and 5(1/2) pounds.
So, there are two baskets that weigh more than 4 but less than 6.
Thus, there are two baskets that weigh more than 4 but less than 6.

A ball thrown into the air is modeled by the
equation
h(t) = -t2 + 4t + 5. Where h represents
the height of the ball and t represents
time.
What is the starting height of the ball?
What is the time the ball reaches its
maximum height?
What is the maximum height?
When does the ball hit the ground?
How high is the ball 1 second into
flight?
Answer:
Below in bold.
Step-by-step explanation:
Starting height is when t = 0
It is 5 units.
To find the maximum height we convert the equation to vertex form:
h = -t^2 + 4t + 5
h = -(t^2 - 4t - 5)
= - [(t - 2)^2 - 9]
= -(t - 2)^2 + 9
From this we see that the ball reaches max height after 2.
Maximum height = -2^2 + 4(2) + 5
= 9 units.
Ball reaches the ground after 2*2 = 4 .
Hello, I gotta turn it turn in this question today, help!!!!!!
Answer:
2 or -2
Step-by-step explanation:
If x² - 8x = -12
Step 1
We find x by solving
x² - 8x = -12
We equate to zero
x² - 8x + 12 = 0
We factorise
x² - 6x - 2x + 12 = 0
x(x - 6) -2(x - 6) = 0
(x - 6) (x - 2) = 0
x - 6 = 0, x = 6
x - 2 = 0, x = 2
x = 6 or 2
Step 2
What is x - 4?
When x = 6
= 6 - 4 = 2
When x = 2
= 2 - 4 = -2
Therefore, x - 4 = 2 or -2
Evaluate the expression when m=3. m 2 - 5m + 7
Answer:
-2
Step-by-step explanation:
Substitute 3 for m: (3)2 - 5(3) + 7
Simplify: 6 - 15 + 7
Follow PEMDAS and subtract 6 from 15: -9 + 7
Add: -2
Hope this helps ^-^
You said m = 3.
Replace every m you see with 3.
m^2 - 5m + 7
(3)^2 -5(3) + 7
9 - 15 + 7
-6 + 7 = 1

You are interested in finding a 90% confidence interval for the average number of names that people can correctly recall after being introduced to 40 people at a party. Based on past research, you know that the standard deviation for this number is 6.34 names. Suppose you surveyed 55 randomly selected people and found that they correctly remembered an average of 18.16 names. The standard deviation for this group was 4.28 names. Round your answers to two decimal places.
A. The sampling distribution follows a __________ distribution.
B. With 90% confidence the mean number of names that all people can remember when introduced to 40 people at a party is between ______ and _______
C. If many groups of 55 randomly selected people were surveyed, then a different confidence interval would be produced for each group. About _____ percent of these confidence intervals will contain the true population mean number of names remembered and about ______ percent will not contain the true population mean number of names remembered.
Answer:
A. The sampling distribution follows a normal distribution
B. With 90% confidence the mean number of names that all people can remember when introduced to 40 people at a party is between 17.04 and 19.28
C. If many groups of 55 randomly selected people were surveyed, then a different confidence interval would be produced for each group. About 90 percent of these confidence intervals will contain the true population mean number of names remembered and about 10 percent will not contain the true population mean number of names remembered
Step-by-step explanation:
The given parameters are;
The known population standard deviation of the number of names that people can recall after being introduced to 40 people in a party, σ = 6.34 names
The number of people randomly selected in the survey, n = 55 people
The average number of names correctly remembered, [tex]\overline x_1[/tex] = 18.16
The standard deviation of the group surveyed, s = 4.28
A. Based on the Central Limit Theorem CLT, the sampling distribution follows a normal distribution
B. The 90% confidence interval is given as follows;
[tex]C.I.=\bar{x}\pm z_{\alpha /2}\cdot \dfrac{\sigma}{\sqrt{n}}[/tex]
Where [tex]z_{\alpha /2}[/tex] at 90% = 1.65, we have;
[tex]C.I.=18.16\pm 1.65 \times \dfrac{4.28}{\sqrt{55}}[/tex]
C.I. ≈ 17.20 < μ < 19.11
With 90% confidence the mean number of names that all people can remember when introduced to 40 people at a party is between 17.04 and 19.28
C. The 90% confidence interval gives the certainty that if different groups of 55 randomly selected people were surveyed, then about 90 percent of the confidence intervals will contain the true population mean number of names remembered and about 10 percent will not contain the true population mean number of names remembered.

Finding slope given two points on the line
Find the slope of the line passing through the points (-4, 6) and (3, -8).
Answer:
The slope is -2
Step-by-step explanation:
Hi there!
We are given the points (-4, 6) and (3, -8)
We want to find the slope (m) of the line that passes through these points
We can use the formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] to calculate the slope, where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points
We have everything we need to find the slope, but let's label the values of the points to avoid confusion and mistakes.
[tex]x_1=-4\\y_1=6\\x_2=3\\y_2=-8[/tex]
Now substitute into the formula
m=[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
m=[tex]\frac{-8-6}{3--4}[/tex]
Simplify:
m=[tex]\frac{-8-6}{3+4}[/tex]
m=[tex]\frac{-14}{7}[/tex]
Divide
m = -2
The slope of the line is -2
Hope this helps!

Mathew builds a model of a house that is 2 in tall, 6 in wide, and 3 in long. The real house is 20 ft tall, 60 ft wide and 30ft tall. What is the scale used to build the house?
Answer: 1inch : 10 feet
Step-by-step explanation:
Since we are informed that Mathew builds a model of a house that is 2 in tall, 6 in wide, and 3 in long while the real house is 20 ft tall, 60 ft wide and 30ft tall.
For the length, we can see that the relay house is (30/3) = 10 times the model. The same thing is applicable to others as well as the width and height is 10× the scale used. Therefore, the scale used to build the house is 1inch:10 feet

Answer:
He received $16 change
Step-by-step explanation:
3 books for $18 is $24
4 DVDs for $15 is $60
His total is $84
$100 - $84 = $16
Answer:
6 dollars
Step-by-step explanation:
you multiply 3 by 8 which is 24. Then you multiply 4 by 15 and that's 70. So then you add 24 and 70 together which is 94. Lastly you subtract 94 from 100 and you get 6.
