a blue marble from each bag?
Answer:
A. 0.25
B. 0.5
C. 0.6
D. 0.1
Please help
Answer:
0.25
Step-by-step explanation:
Bag 1 :
Number of marbles = 6
Number of Blue marbles = 3
Bag 2:
Number of marbles = 4
Number of Blue marbles = 2
Recall :
Probability = required outcome / Total possible outcomes
For Bag 1:
P(blue) = Number of Blue marbles / total marbles
P(blue) = 3 / 6 = 1/ 2
For Bag 2:
P(blue) = Number of Blue marbles / total marbles
P(blue) = 2 / 4 = 1/ 2
Probability of a picking a blue marble from each bag :
1/2 * 1/2 = 1/4 = 0.25

Jace measured a line to be 14 inches long. If the actual length of the line is
13.1 inches, then what was the percent error of the measurement, to the
nearest tenth of a percent?
Answer:
6.87022901%
Step-by-step explanation:
He measured 14 out of 13.1 inches. There is a difference of 0.9 inches when u subtract. He miscalculated by 0.9 out of 13.1. In a calculator you divide .9 by 13.1 you get 0.0687022901. Multiply by 100 to get the percent and round it to your desired decimal place.

rewrite a^5 x a^-3 in the form a^n
Answer:
The answer is A^2
Step-by-step explanation:
When you are dividing, You subtract exponents if they have the same base.
The base (variables) are the same. So you subtract the powers.
Which are 5 and -3. You subtract those two powers 5 minus negative -3 which gives you 2. So it's a^-2

A recent drug survey showed an increase in use of drugs and alcohol among local high school students as compared to the national percent. Suppose that a survey of 100 local youths and 100 national youths is conducted to see if the percentage of drug and alcohol use is higher locally than nationally. Locally, 65 seniors reported using drugs or alcohol within the past month, while 61 national seniors reported using them.
Required:
Conduct a hypothesis test at the 5% level.
Answer:
We fail to reject H0
Step-by-step explanation:
Null hypothesis : H0 : Plocal ≤ Pnational
Alternative hypothesis : H1 : Plocal > Pnational
Plocal = P1 = 65/100 = 0.65
Pnational = P2 = 61/100 = 0.61
n1 = 100 ; n2 = 100
Mean, m = P1 - P2 = 0.65 - 0.61 = 0.04
The standard deviation : = sqrt(Variance)
Variance = P1(1 - P1) /n1 + P2(1 - P2) /n2
Variance = 0.65(0.35)/100 + 0.61(0.39)/100
Variance = 0.002275 + 0.002379 = 0.004654
Standard deviation (s) = √(0.004654) = 0.06822
Z = m/s = 0.04 / 0.06822 = 0.586
Using the p-value from Z score calculator :
Hence, Pvalue for a Zscore 0.586 at 5% = 0.278938
Since ;
P-value is > α ; 0.278938 > 0.05
Then we fail to reject H0

Step-by-step explanation:
b) 27 / 10%
Divide 27 by 10/100 by multiplying 27 by the reciprocal of 10/100.
27 x 100/10
Multiply 27 and 100 to get 2700.
2700/10
Divide 2700 by 10 to get 270.
270
Divide 270 by 100 to get 2.7
Subtract 27.00 - 2.7 = 24.30

3. Technology required. Gateway Arch in St. Louis, Missouri, is 630 feet tall. Priya can look
up at a 50 degree angle to see the top of the arch. How far away from the base of the
arch is she standing?
Priya is standing 528.63 feet away from the base of Gateway Arch in St. Missouri.
What is trigonometry?In the field of mathematics known as trigonometry, correlations between angles and length ratios are studied. The field was created in the Hellenistic era in the third century BC as a result of the use of geometry in astronomical research.
Given parameters:
Height of the Gateway Arch in St. Missouri = 630 feet.
Priya have to look up at a 50° angle to see the top of the arch.
Now from definition of tanθ in trigonometry:
tan50° = height of the Gateway Arch in St. Missouri ÷ distance of Gateway Arch in St. Missouri
hence, distance of Gateway Arch in St. Missouri = height of Gateway Arch in St. Missouri ÷ tan50°
= 630 feet ÷ tan50°
= 528.63 feet.
Hence, she is standing 528.63 feet away from the base of Gateway Arch in St. Missouri.

In triangle ABC, the size of angle B is 4 times the size of angle A, and the size of
angle C is 1° less than 5 times the size of angle A.
Find the size of the angles.
Answer:
A=18.1, B=72.4, and C=89.5
Step-by-step explanation:
Where A, B and C represent their respective angles:
We are given that:
B=4A
C=5A−1
And since ABC make up a triangle, we know that:
A+B+C=180
Since we have three variables and three equations, we can solve for A, B, and C. To solve for A:
Take the equations B=4A and C=5A−1, and plug B and C into the last equation:
A+B+C=180
A+4A+5A−1=180
10A – 1 + 1 = 180 + 1
10A=181
10 /10 x A = 181/10
A = 18.1
Then we can plug this value into the first two equations to solve for B and C:
B=4A
B=4(18.1)=72.4
C=5A−1
C=5(18.1)−1= 90.5 - 1=89.5
So A=18.1, B=72.4, and C=89.5
Hope this helps!
The size of ∠A is 18.1°.
The size of ∠B is 72.4°.
The size of ∠C is 89.5°.
What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
We have,
Triangle ABC
∠A = x
∠B = 4x
∠C = 5x - 1
Now,
The sum of all the angles in a triangle is 180.
This means,
x + 4x + 5x - 1 = 180
10x - 1 = 180
10x = 181
x = 18.1
Now,
∠A = 18.1°
∠B = 4 x 18.1 = 72.4°
∠C = 5 x 18.1 - 1 = 89.5°
Thus,
The sizes of the angles are:
18.1°, 72.4°, and 89.5°
