Parker has 12 blue marbles. Richard has 3/4 of blue marbles that Parker has.
Explain how you know that Parker has more blue marbles than Richard without completing the multiplication. Enter equal to, greater than, or less than in each box.
Answer:
Parker>Richard
Step-by-step explanation:
So we know Parker has 12 marbles(blue) and Richard has 3/4(.75) of that.
You do not need multiplication as the answer is above this
Come on look above, what do you see?
Richard has .75 or 75% or 3/4 but not 1 or higher so he has less
Answer: Parker>Richard
The number of marbles Parker has > the Number of marbles Richard has.
Parker has 12 blue markers.
Richard has 3/4 of the blue marbles that Parker has.
What is a fraction?A fraction represents a part of a whole or, more generally, any number of equal parts.
For example, when We say 3/4, it means there will be 4 equal parts out of which we are considering 3 parts.
Same way, Richard has 3/4 of the blue marbles that Parker has.
This means Parker has 4 equal parts of 12 marbles.
This means Parker has 4 equal parts with each part consisting of 3 marbles.
Since each part contains 3 marbles
So 3 parts will contain 3+3+3 =9 marbles
Since Richard has 3 parts of the blue marbles that Parker has.
This means Richard has 9 marbles.
Therefore, the Number of marbles Parker has > the Number of marbles Richard has.

Pablo wants to get a grade of at least 95 in math this semesterSo far he has test scores of 89 98, 97 and 92. He will take his last test on Friday What is the lowest grade he can get on the test and still get a 95 this semester?
Answer:
the answer is 97 if you're rounding but 99 if you want exactly 95
Step-by-step explanation:
if you add all the previous grades up it'll add up to 376 and then when you add 97 and then divide it by 5 (the total amount of assignments) it'll add up to 94.6 which rounds up to a 95 unless you want it a 95 exactly which would probably be 99
Answer:
99
Step-by-step explanation:
Relative to his desired average, Pablo's scores are ...
-6, +3, +2, -3
In order for his average grade to be 95, the sum of all of these deviations and the one on his last test must be zero
-6 +3 +2 -3 +x = 0
x = 4
Pablo must get a 95+4 = 99 on his last test to have a 95 average.

Grades on a standardized test are known to have a mean of 1000 for students in the United States. The test is administered to 453 randomly selected students in Florida; in this sample, the mean is 1013, and the standard deviation (s) is 108. a. Construct a 95% confidence interval for the average test score for students in Florida. b. Is there statistically significant evidence that students in Florida perform differently from other students in the United States
Answer:
a
The 95% confidence interval is [tex]1003 < \mu <1023[/tex]
b
Yes there is statistically significant evidence that students in Florida perform differently from other students in the United States
Step-by-step explanation:
From the question we are told that
The population mean is [tex]\mu = 1000[/tex]
The sample size is [tex]n = 453[/tex]
The sample mean is [tex]\= x = 1013[/tex]
The standard deviation is [tex]s = 108[/tex]
Given that the confidence level is 95% then the level of significance is mathematically represented as
[tex]\alpha = 100 - 95[/tex]
=> [tex]\alpha = 5\%[/tex]
=> [tex]\alpha = 0.05[/tex]
The critical value for [tex]\frac{\alpha }{2}[/tex] obtained from the normal distribution table is
[tex]Z_{\frac{\alpha }{2} } = 1.96[/tex]
Generally the margin of error is mathematically represented as
[tex]E = Z_{\frac{\alpha }{2} } * \frac{s}{\sqrt{n} }[/tex]
=> [tex]E = 1.96 * \frac{108}{\sqrt{453} }[/tex]
=> [tex]E = 9.946[/tex]
Generally the 95% confidence interval is mathematically represented as
[tex]\= x - E < \mu < \= x + E[/tex]
=> [tex]1013 - 9.946 < \mu < 1013 + 9.946[/tex]
=> [tex]1003 < \mu <1023[/tex]
Given that the population mean(1000) is not within the 95% confidence interval for l for the average test score for students in Florida, then it means that there is statistically significant evidence that students in Florida perform differently from other students in the United States

that passes through the point(2,2)
Write an equation of a line that is perpendicular to y = 1/4x-4
that passes through the point(2.8)
Answer:
Step-by-step explanation:
1. perp. 1/2
y - 2 = 1/2(x - 4)
y - 2 = 1/2x - 2
y = 1/2x
2. 2y = -4x + 8
y = -2x + 4
perp. 1/2
y - 2 = 1/2(x - 6)
y - 2 = 1/2x - 3
y = 1/2x - 1
3. perp. -3/2
y - 2 = -3/2(x - 2)
y - 2 = -3/2x + 3
y = -3/2x + 5
4. perp. -4
y - 8 = -4(x - 2)
y - 8 = -4x + 8
y = -4x + 16
How to calculate a 15% tip?
(5 points) A random sample of adult drivers was obtained where 50% were men and 49% were women. Note that everyone is not classified as a man or a woman. A survey showed that 77% of the drivers rely on GPS systems. 38% of the drivers are men and use GPS while 38% of the drivers are women and use GPS. Suppose a person included in this survey is randomly selected. (0.5 pts.) a) Suppose the person selected is a man. What is the probability that he relies on a GPS system
Answer:
the probabiility that the selected man relies on a GPS system is 0.494
Step-by-step explanation:
From the given information:
Let X be the event that selected person is a man
Let Y be the event that selected person is a woman
Let Z be the event that selected relies or use GPS system.
So;
the following probabilities are:
P(X) = 0.50
P(Y) = 0.49
P(Z) = 0.77
P(X ∩ Z) = 0.38
P(Y ∩ Z) = 0.38
Now;
if the selected person is a man, the probability that he relies on a GPS system can be determined as follows:
[tex]P(Z|X) = \dfrac{P(X \cap Z)}{P(Z)}[/tex]
[tex]P(Z|X) = \dfrac{0.38}{0.77}[/tex]
[tex]\mathbf{P(Z|X) =0.494}[/tex]
Thus, the probabiility that the selected man relies on a GPS system is 0.494
solve each equation 4(a+5)=10+4a
Answer:
10 = a
Step-by-step explanation:
To find this answer, first you need to distribute 4 times a and 4 times 5, since this is in parenthesis. You should get 4a + 20 = 10 + 4a. From there, you can subtract 4a from both sides of the equal sign, which will cancel out one of the 4a's. You should be left with 20 = 10 + a. Finally, you can subtract 10 from both sides of the equal sign and get 10 = a.

Solve using elimination method
11x + 9y = -5
7x + 5y = -1
Answer: (2,-3)
Step-by-step explanation:
To solve by elimination method, we need to choose which variable to eliminate. Let's eliminate y. We need to make sure that the y coefficients in both equations are equal. To do that, you multiply the first equation by 5 and the second by 9.
(11x + 9y = -5)5 [multiply entire equation by 5]
(7x + 5y = -1)9 [multiply entire equation by 9]
--------------------------------------------------------------------------------------------------------
55x+45y=-25
63x+45y=-9
Now that the y are both the same, we can eliminate y by subtracting both equations and solve.
-8x=-16 [divide both sides by -8]
x=2
Now that we have x=2, we can plug that in to any equation to find y.
7(2)+5y=-1 [multiply]
14+5y=-1 [subtract both sides by 14]
5y=-15 [divide both sides by 5]
y=-3
With the y-value, we know that the answer is (2,-3).

A brick layer is able to set 2.5 breaks in one minute how many bricks can you set an eight hours
Answer:
In 8 hours he will set 1200 bricksStep-by-step explanation:
In this problem, we are expected to estimate the number of bricks he can set in 8 hours.
let us convert hours to minutes we have
60 min make 1 hour
x min make 8 hours
cross multiply
x= 60*8
x= 480 min
We are assuming the same rate with which he sets 2.5 brick is the same as the rate with which he will set bricks for the 8 hours windows
so if the bricklayer sets
2.5 bricks in 1min
y bricks in 480 min
Cross multiply we have
y=2.5*480
y= 1200 bricks
hence in 8 hours, he will set 1200 bricks

3. Five kissing cousins met at a family reunion.
Each cousin kissed each of the other cousins
just once. How many kisses were given in all?
Answer: 20 kisses
Step-by-step explanation:
given data:
number of cousins at the family reunion = 5
each cousing kissing each other just once.
if one cousin kisses everybody round that would be
= 1 * 4
= 4 kisses.
4 kisses from each cousins * number of cousins at the family reunion.
= 4 * 5
= 20 kisses.
in total there were 20 kisses at family reunion
Using the principle of combination, the number of kisses given in all by the five cousins is 10
Number of cousins, n = 5Using the relation :
[n(n-1)] ÷ 2Substituting the values into the relation :
[n(n-1)] ÷ 2
[5(5-1)] ÷ 2
(5 × 4) ÷ 2
20 ÷ 2
= 10 kisses
Hence, the Number of kisses exchanged in all is 10.
