Simplify the ratio 4:26
Answer:
The simplest form of 426 is 213.
Answer:
2:13
Step-by-step explanation:
To simplify the ratio 4:26, we find the greatest common divisor of 4 and 26, and then we divide 4 and 26 by the greatest common divisor.
The greatest common divisor that you can use to simplify 4:26 is 2. Which means the answer to ratio 4:26 simplified is 2:13.

What is a 90% confidence interval for the true proportion of adult drivers who have often or sometimes talk on a cell phone when driving
The question is incomplete. Here is the complete question.
USA Today reported that 36% of adult drivers admit that they often or sometimes talk on a cell phone when driving. This was based on a random sample of 1004 adult drivers.
a) What is a 90% confidence interval for the true proportion of adult drivers who have often or sometimes talk on a cell phone when driving?
b) What is a 95% confidence interval for the true proportion of adult drivers who have often or sometimes talk on a cell phone when driving?
c) What is a 99% confidence interval for the true proportion of adult drivers who have often or sometimes talk on a cell phone when driving?
d) What do you notice?
Answer and Step-by-step explanation: The way to calculate confidence interval for proportions is by using the following formula:
[tex]z(\sqrt{\frac{p(1-p)}{n} } )[/tex]
where
p is the sample population proportion
n is the number of individuals in the sample
z is z-score associated of the % of confidence
a) A 90% confidence has a z-score of z = 1.645
Calculating:
Interval = [tex]1.645(\sqrt{\frac{0.36(1-0.36)}{1004} } )[/tex]
Interval = [tex]1.645(\sqrt{0.00023} )[/tex]
Interval = [tex]1.645(0.01515)[/tex]
Interval = 0.025
A 90% Confidence interval for true population is between 0.335 and 0.385.
b) A 95% confidence has a z-score of z = 1.96
Since the sample parameter didn't change, the interval will be:
Interval = 1.96(0.01515)
Interval = 0.03
For a 95% confidence, interval is between 0.33 and 0.39.
c) A 99% confidence has a z-score of z = 2.58
Interval = 2.58(0.01515)
Interval = 0.39
For a 99% confidence, interval is between -0.03 and 0.75
d) Confidence interval tells you how certain your results from polling or survey would represent the real population's behaviour. In the experiment above, as the percentage of certainty grows, closer the real population proportion actually is for adult drivers who often or sometimes talk on a cell phone when driving.

A typical person has an average heart rate of 71.0 beats/min. Calculate the given questions. How many beats does she have in 4.0 years
Answer:
37317600 beats she will have in 4 years.
Step-by-step explanation:
Given that,
A typical person has an average heart rate of 71.0 beats/min.
We need to find the number of beats she have in 4 years.
As 1 year = 525600 min
1 min = 71 beats
525600 min = 525600 × 71
=37317600 beats
Hence, 37317600 beats she will have in 4 years.

Michelle is an architect who builds skyscrapers. She has a sheet of measurements that she needs convert before she can begin her next project. One wall is 12 ⅜ ft long and has a width of 19.73 ft. Change the given mixed number to a decimal. Circle the correct response.
A 12.3 ft
B 12.375 ft
C 12.38 ft
D 12.83 ft
Answer:
B 12.375 is the answer
Step-by-step explanation:
Key skills needed: Fraction to Decimal Conversion
1) The mixed number that is in the question is --> [tex]12\frac{3}{8}[/tex]
2) We need to find 12 and 3/8 as a decimal.
[tex]12\frac{3}{8}= 12 + \frac{3}{8}[/tex]
This means it would be 12."something"
We need to find out what [tex]\frac{3}{8}[/tex] as a decimal is.
3) To do this, we do 3 ÷ 8 (to find the decimal form of a fraction, you do the numerator divided by the denominator).
4) Check the image I posted to see how I did 3 ÷ 8.
5) Well based on the division, 3 divided by 8 is 0.375
This means that [tex]12 + \frac{3}{8} = 12 + 0.375 = 12.375[/tex]
Therefore 12.375 is your answer

Answer:
y = 95° and x = 21°
Step-by-step explanation:
y + 85° = 180° { being co-interior angles }
y = 180° - 85°
y = 95°
y = 4x + 11°[ being vertically opposite angles ]
95° = 4x + 11°
4x = 95° - 11°
4x = 84°
x = 84° / 4
x = 21°

Answer: 6 cm
Step-by-step explanation:
The surface area of the given shape is 80 cm².
From the given figure, the dimensions of large cuboid is length= 5 cm, width= 3 cm and height= 2 cm.
What is surface area of a cuboid?The surface area of a cuboid is the total space occupied by it. A cuboid is a six-faced three-dimensional shape in which each face is in the shape of a rectangle.
Formula to find the total surface area of a cuboid is 2(lw+wh+lh)
Surface area of a large cuboid
= 2(5×3+3×2+5×2)
= 2(15+6+10)
= 2×31
= 62 cm²
The dimensions of smaller cuboid is length= 1 cm, width= 1 cm and height= 4 cm
Surface area of a smaller cuboid
= 2(1×1+1×4+1×4)
= 2(1+4+4)
= 2×9
= 18 cm²
Total surface area = 62+18
= 80 cm²
Therefore, the surface area of the given shape is 80 cm².

Question 14 (5 points)
(05.02 LC)
What is the value of x in the solution to the following system of equations? (5 points)
x − 2y = 2
3x + y = 6
Answer:
x = 2 and y = 0
Step-by-step explanation:
x - 2y = 2
3x + y = 6
using the substitution method, we solve the first equation for 'x' to get
x = 2y + 2
plug that into 'x' in the second equation
3(2y + 2) + y = 6
6y + 6 + y = 6
7y = 0
y = 0
find 'x':
3x + 0 = 6
x = 6/3
x = 2
Answer:
x=2
