On a recent quiz, the class mean was 69 with a standard deviation of 4.8. Calculate the z score for a person who received score of 74. z score:
Answer:
1.04167
Step-by-step explanation:
Z -score formula is given as
z = (x-μ)/σ, where
x is the raw score = 74
μ is the population mean = 69
σ is the population standard deviation = 4.8
Z score = x - μ/ σ
= 74 - 69/4.8
= 1.04167
The z score for a person is given as 1.04167

Square OABC is drawn on a centimetre grid.
O is (0,0) Ais (3,0) Bis (3, 3) C is (0, 3)
Write down how many invariant points there are on the perimeter of the square when
OABC is reflected in y = x
Answer:
No invariant point
Step-by-step explanation:
Yo!
When we translate a form, in this case a polygon We must observe the direction of the vector. Since our vector is:
1) Let's apply that translation to this polygon, a square. Check it below:
2) The invariant points are the points that didn't change after the transformation, simply put the points that haven't changed.
Examining the graph, we can see that no, there is not an invariant point, after the translation. There is no common point that belongs to OABC and O'A'B'C' simultaneously. All points moved.

A square sign has a height and width of 2 1/2 feet. Will the area of the sign be greater or less that 2 1/2 square
Answer:
Greater
Step-by-step explanation:
Area of the square sign = L²
L is the side length of the square
Given
L = 2 1/2 feet
Area of the sign = 2 1/2 * 2 1/2
Area of the sign = 5/2 * 5/2
Area of the sign = 25/4
Area of the sign = 8 1/4 square feet
This shows that the area of the sign will be greater than 2 1/2 square feet

How do you multiply fractions?
Answer: 2/7
Step-by-step explanation:
You take the top numbers and multiply them and then take the bottom numbers and multiply them and then you simplify.
1/3 × 6/7 = 6/21 = 2/7
To multiply fractions we'll multiply numerator with the numerator and denominator with the denominator and simplify (1/3 × 6/7) = 6/21 = 2/7.
What are fractions?Fractions are written in p/q form,where q ≠ 0 as it would become undefined.Fractions are of two types one is proper fraction and another one is improper fraction.
A fraction is is the form of numerator divided by the denominator.
To multiply two or more fraction we simply have to multiply numerator with the numerator and denominator with the deominator to combine them into one fraction and then we simplify the combined fraction until both the numerator and the denominator has HCF of 1.
Given (1/3 × 6/7) which is,
= 6/21.
= 2/7.

Lydia has drawn quadrilateral ABCD with diagonal AC . According to her measurements, m∠DAC=m∠BCA and m∠DCA=m∠BAC . Without taking additional measurements, Lydia claims △ABC≅△CDA according to the ASA triangle congruence criteria. Explain why Lydia is correct.
Answer:
Lydia is correct because the ASA criterion for triangle congruence states that if two triangles have two pairs of congruent angles and the common side of the angles in one triangle is congruent to the corresponding side in the other triangle, then the triangles are congruent which would prove her statement correct.

A publisher reports that 30% of their readers own a particular make of car. A marketing executive wants to test the claim that the percentage is actually more than the reported percentage. A random sample of 100 found that 37% of the readers owned a particular make of car. Is there sufficient evidence at the 0.02 level to support the executive's claim
Answer:
we will fail to reject the null hypothesis and conclude that there's insufficient evidence to support the claim that the percentage is actually more than the reported percentage
Step-by-step explanation:
We are given;
Population proportion; p = 30% = 0.3
Sample proportion; p^ = 37% = 0.37
Sample size; n = 100
Let's define the hypotheses;
Null hypothesis; H0: p ≤ 0.3
Alternative hypothesis; Ha: p > 0.3
Formula for the test statistic is;
z = (p^ - p)/√(p(1 - p)/n)
Thus;
z = (0.37 - 0.3)/√(0.3(1 - 0.3)/100)
z = 0.07/0.04582575695
z = 1.53
From z-distribution table, at z=1.53 we have;
p-value = 1 - 0.9370 = 0.063
This p-value is greater than the significance level of 0.02 and thus we will fail to reject the null hypothesis and conclude that there's insufficient evidence to support the claim that the percentage is actually more than the reported percentage
Write an equation of the locus of all points equidistant from the x axis and the y axis and whose coordinates have the opposite signs.
Answer:
y=-x
Step-by-step explanation:
Since the y-axis and x-axis are intersecting lines then you need to apply the locus of intersecting lines which would be the angle bisector and since the problem is asking for the opposite signs you need to make it -x instead of x.

In ΔCAB, if m∠A = 10x + 9, m∠B = 34°, and m∠C = 97°, what is the value of x?
triangle CAB, point E is on segment AC between points A and C and point D is on segment BC between points B and C, creating segment ED
x = 2
x = 3
x = 4
x = 5
Answer:
x = 4
Step-by-step explanation:
(10x + 9) + 34 + 97 = 180
10x +140 = 180
10x = 40
x = 4
The value of x in the given angles of the traingle CAB for angle m∠A is determined as 4.
Sum of angles in a triangleThe sum of angles in a triangle can be used to determine the value of x in the given angles above.
m∠A + m∠B + m∠C = 180 (sum of angles in a triangle)
10x + 9 + 34 + 97 = 180
10x + 140 = 180
10x = 40
divide both sides by 10;
x = 40/10
x = 4
Thus, the value of x in the given angles of the traingle CAB for angle m∠A is determined as 4.

[tex]c=\sqrt{32}[/tex]
Step-by-step explanation:
When we solve for this we should always remember this formula [tex]a^2+b^2=c^2[/tex] and since we already know a and b we can plug that in to find out what c could be but we won't actually solve it.
[tex]a^2+b^2=c^2\\4^2+4^2=c^2\\16+16=c^2\\32=c^2\\\sqrt{c^2}=\sqrt{32}\\c=\sqrt{32}[/tex]
So c would equal whatever the square root of 32 is.
