What is the remainder when 7842 is divided by 176
Answer: 5 or 55
Step-by-step explanation:
The remainder is 98 when 7842 is divided by 176 after using the arithmetic operation.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
We have two numbers:
7842 and 176
7842 is divided by 176
Mathematically,
= 7842 ÷ 176
We can write the above number expression in the form of a fraction:
= 7842/176
Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
The remainder will be:
Quotient = 44
Remainder = 98
Thus, the remainder is 98 when 7842 is divided by 176 after using the arithmetic operation.

(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

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

y - 2 = -3/2x + 3
y = -3/2x + 5
4. perp. -4
y - 8 = -4(x - 2)
y - 8 = -4x + 8
y = -4x + 16

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.

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.

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

Answer:
x = 21
Step-by-step explanation:
Step 1: Write out equation
-5x - 72 = -12x + 75
Step 2: Add 5x to both sides
-72 = -7x + 75
Step 3: Subtract 75 on both sides
-147 = -7x
Step 4: Divide both sides by -7

Where would the plane STV intersect plane Z?
Answer:
Plane Z or plane VTX.
Step-by-step explanation:
From the picture attached,
ST pierces the plane at a point T.
That means line ST is perpendicular to the horizontal plane Z or plane VTX.
Since, S is a point lying on line ST it will not lie on the vertical plane VTX Or plane Z.
Therefore, point S is not contained in the plane Z.
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.

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.

Solve the equation 34 - (x + 8) = 6x-2
Answer:
x = 4
Step-by-step explanation:
To solve the equation, we would have to solve for the variable x.
34 - (x + 8) = 6x - 2
Remove the parentheses.
34 - x - 8 = 6x - 2
Add 2 to both sides and combine like terms.
28 - x = 6x
Add x to both sides.
28 = 7x
Swap sides.
7x = 28
Divide both sides by 7.
x = 4
So the solution to the equation would be x = 4
