Answers
Answer:
60%
Step-by-step explanation:
percent of green marbles = (total number of green marbles / total number of marbles in the bag) x 100
total number of marbles in the bag = 30 + 20 = 50
30 / 50 x 100 = 60%

In an all boys school, the height of the student body are normally distributed with a mean of 69 inches and a standard deviation of 5 inches. using the empirical rule, what percentage of the boys are between 54 and 84 inches tall?
Answers
Answer:
99.7% of the boys are between 54 and 84 inches tall.
Step-by-step explanation:
The heights 54 and 84 inches are 3 standard deviations away from the mean. Thus, 99.7% of the boys are between 54 and 84 inches tall.
The percentage of the boys are between 54 and 84 inches tall is 99.7%
What is percentage?
Percentage a relative value indicating hundredth parts of any quantity.
What is empirical rule?
The empirical rule or the three-sigma rule , is a statistical rule which states that for a normal distribution, almost all observed data will fall within three standard deviations of the mean.
The empirical rule predicts that 68% of observations falls within the first standard deviation (µ ± σ), 95% within the first two standard deviations (µ ± 2σ), and 99.7% within the first three standard deviations (µ ± 3σ).
From question mean(μ) = 69 in. and standard deviation(σ)= 5 in.
(µ ± σ) = (69 ± 5)
=64 - 74
=68%
(µ ± 2σ) =(69 ± 10)
=59 -79
=95%
(µ ± 3σ) =(69 ± 15)
=54 -84
= 99.7%
Thus the percentage of the boys are between 54 and 84 inches tall is 99.7%

We have,
[tex]\dfrac{\sqrt{2}}{2}[/tex]
It can be written as:
[tex]\dfrac{\sqrt{2}}{2}=\dfrac{1}{\sqrt{2}}[/tex]
From the standard trigonometric table, we get
[tex]\sin 30^\circ=\dfrac{1}{2}[/tex]
[tex]\sin 45^\circ=\dfrac{1}{\sqrt{2}}[/tex]
[tex]\cos 45^\circ=\dfrac{1}{\sqrt{2}}[/tex]
[tex]\cos 60^\circ=\dfrac{1}{2}[/tex]
[tex]\tan 30^\circ=\dfrac{1}{\sqrt{3}}[/tex]
[tex]\tan 45^\circ=1[/tex]
From the above values it is clear that the value of [tex]\sin 45^\circ [/tex] and [tex]\cos 45^\circ [/tex] are equal to [tex]\dfrac{1}{\sqrt{2}}[/tex].
Therefore, [tex]\sin 45^\circ [/tex] and [tex]\cos 45^\circ [/tex] and equal to [tex]\dfrac{\sqrt{2}}{2}[/tex]. So, options B and C are correct.

Kayla buys a two-pint bottle of juice for $3.20. What is the unit rate of the cost of the juice per fluid ounce?
Answers
Answer: $0.10 per fluid ounce
Step-by-step explanation:
Kayla bought two-pints for $3.20.
First convert this quantity to fluid ounces.
1 pint = 16 fluid ounces
If 2 pints were bought therefore, this would be:
= 2 * 16
= 32 fluid ounces
32 fluid ounces cost $3.20.
Cost per fluid ounce is therefore:
= 3.20 / 32
= $0.10 per fluid ounce
Answer:

L U C K luck is parallelogram with ∠C=68° and ∠LUK=42° find: 1.
m∠ CUK 2. m∠ K
Answers
Answer:
1. m∠CUK = 70°
2. m∠K = 112°
Step-by-step explanation:
1. The given parameters of the parallelogram LUCK are;
∠C = 68°
∠LUK = 42°
From the diagram of parallelogram LUCK obtained from an online source, we have;
Given that LUCK = A parallelogram, we have;
The same side interior angles ∠C and ∠U are supplementary angles
Therefore;
∠C + ∠U = 180°
∠U = 180° - ∠ C
∴ ∠U = 180° - 68° = 112°
∠U = 112°
By angle addition property, ∠U = ∠LUK + ∠CUK
∴ m∠CUK = ∠U - ∠LUK
By plugging in the value of ∠LUK = 42°, and ∠U = 112°, we have;
m∠CUK = ∠U - ∠LUK = 112° - 42° = 70°
m∠CUK = 70°
2. By angle addition property, we have;
∠K = ∠LKU + ∠CKU
∠LKU and ∠CUK are alternate interior angles
∴ ∠LKU = ∠CUK = 70°
Similarly, ∠CKU and ∠LUK are alternate interior angles
∠CKU = ∠LUK = 42°
m∠K = ∠LKU + ∠CKU = 70° + 42° = 112°
m∠K = 112°.

Answers
Answer:
3/50
Step-by-step explanation:
Slope m = y2-y1/x2-x1
From the coordinate
x1 = 2/5, y1 = 2/3, x2 = -4/9 and y2 = 3/5
Substitute;
m = (3/5 - 2/3)/-4/9-2/3
m = (9-10/15)/(-4-6/9)
m = -1/15/-10/9
m = -1/15 * -9/10
m = 9/150
m = 3/50
Hence the slope of the line passing through the points is 3/50
