Answer:
y= =1/2x-8
Step-by-step explanation:
The caffeine content of 8-ounce cans of a certain cola drink is approximately normally distributed with mean 33 milliogram. A randomly selected 8-ounce can containing 35mg of caffeine is 1.2 standard deviations above the mean. Approximately what percent of 8-ounce cans of the cola have a caffeine content greater than 35mg?
Answer:
12%
Step-by-step explanation:
Step 1
We find the standard deviation
A randomly selected 8-ounce can containing 35mg of caffeine is 1.2 standard deviations above the mean.
Mean = 33mg
35 = Mean - 1.2(standard deviation)
35 = 33 + 1.2(standard deviation)
35 - 33 = 1.2(standard deviation)
2 = 1.2(standard deviation)
Standard deviation = 2/1.2
= 1.6666666667
= 1.67
Therefore, the standard deviation is 1.67
Step 2
Using the z score formula
Z score = x - μ/σ
x = 35mg
μ = mean = 33mg
σ= standard deviation = 1.67
= 35 - 33/1.67
= 1.1976
Probabilty value from Z-Table:
P(x<35) = 0.88446
P(x>35) = 1 - P(x<35)
= 1 - 0.88446
= 0.11554
Converting to percentage = 0.11554 × 100
= 11.554%
≈ 12%
Therefore, the percent of 8-ounce cans of the cola having a caffeine content greater than 35mg is approximately 12%
Using the normal distribution, it is found that 11.5% of 8-ounce cans of the cola have a caffeine content greater than 35mg.
In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.In this problem, a randomly selected 8-ounce can containing 35mg of caffeine is 1.2 standard deviations above the mean, which means that the z-score is Z = 1.2.
The percent of 8-ounce cans of the cola have a caffeine content greater than 35mg is 1 subtracted by the p-value of Z = 1.2, so:
Looking at the z-table, Z = 1.2 has a p-value of 0.885.
1 - 0.885 = 0.115
11.5% of 8-ounce cans of the cola have a caffeine content greater than 35mg.

Twelve more than half a number is 10.
Answer:
1/2×+12=10, x=-4
Step-by-step explanation:
Just trust me on this
Answer:
1/2x+12=10
x= -4
Step-by-step explanation:
First subtract 12 from both sides and get 1/2x= -2
Then divide both sides by 1/2
So 2/1 (you flip the fraction to "divide" it which is just multiplying because it is easier) 2/1 times -2 is -4

Sarah’s parents are concerned that she seems short for her age. Their doctor has the following record of Sarah’s height:
Age: 36,48,51,54,57,60
Height: 82,93,94,98,99,103
Answer:
a) Please find the attached scatter plot
b) Y = 0.85·X + 51.843
c) The intercept = Sarah's height at birth
The slope = Sarah's monthly growth rate
d) Sarah's height in 50 years (600 months) will be 221.198 inches
d) The generality of the population stop growing taller when they reach 216 months old
Step-by-step explanation:
a) Please find attached the scatter plot included here
b) From Microsoft Excel, we have;
N = 6
(ΣX)² = 93636
ΣX = 306
ΣY = 569
ΣXY = 29325
ΣX² = 15966
The equation for the least squares regression line is Y = b·X + a
Where;
[tex]a = \dfrac{\sum Y - b\sum X}{N}[/tex]
[tex]b = \dfrac{N\sum XY - \left (\sum X \right )\left (\sum Y \right )}{N\sum X^{2} - \left (\sum X \right )^{2}}[/tex]
Substituting the values, gives;
[tex]b = \dfrac{6 \times 29325- 306 \times 569}{6 \times 15966 - 93636} = 0.85[/tex]
[tex]a = \dfrac{569 - 0.85 \times 306}{6} = 51.48\bar 3[/tex]
The equation of the least squares regression line is Y = 0.85·X + 51.843
c) The intercept gives the Sarah's height at birth, while the slope gives the increase in Sarah's height every month
d) In 50 years, which is equivalent to 600 months, we will have;
Y = 0.85 × 600 + 51.843 = 561.843 cm
2.54 cm = 1 inches
Therefore;
561.843 cm = 561.843 cm/2.41 × inches/cm ≈ 221.198 inches (18.43317 feet)
Sarah's height in 50 years (600 months) = 221.198 inches
d) The reason for the impossibly large height is that the generality of the population stop growing taller by 18 years of age which is 216 months.

Answer:
1. 3cm
2. 6m
Step-by-step explanation:
If all angles are right angles, it means that both lengths on the right side add up to the length on the left side.
For the first one, the length on the left is 7cm, and there are two lengths on the right: 4cm and an unknown we can call 'x'.
We know that both of the right lengths add to the left length so we can represent this as so:
4+x=7
To solve for x we can minus 4 from both sides:
x+4-4 = 7-4
x = 7 -4
x = 3cm
We can solve the second one in a similar fashion:
x + 6 = 12
x + 6 - 6 = 12 - 6
x = 12 - 6
x = 6m

Temperature Suppose there is a 1.9°F drop in temperature for every thousand feet that an airplane
climbs into the sky. If the temperature on the ground is 48.4°F, what will be the temperature when the
plane reaches an altitude of 10,000 ft?
The temperature will be °F. (Type an integer or a decimal.)
Answer:
29.4 °F
Step-by-step explanation:
There are ten thousands in 10,000. (Amazing, eh?) So, the temperature will drop by 10 × 1.9 °F = 19 °F.
A drop of 19 °F from 48.4 °F is ...
48.4 -19 = 29.4
The temperature at 10,000 ft will be 29.4 °F.

Divide the first digit of the dividend (2) by the divisor (14). Since 2 is smaller than 14, we bring down the next digit (3) to make a two-digit number.
Divide the two-digit number (23) by the divisor (14). The quotient is 1, and the remainder is 9.
Bring down the next digit (6) to the remainder (9) to form 96.
Divide 96 by 14. The quotient is 6, and the remainder is 12.
Step 5: Bring down the next digit (0) to the remainder (12) to form 120.
Divide 120 by 14. The quotient is 8, and the remainder is 8.
Since there is no more digit to bring down, the division process is complete.
Therefore, 236 divided by 14 equals 16 with a remainder of 8.

R
A. 30°
B. 75°
C. 60°
D. 45°
Answer:
D. 45
Step-by-step explanation:
All angles have to = 180°
60 + 75 + <RVE = 180°
135 + RVE = 180°
180 - 135 = 45° RVE
RVE = 45°
Another way to check your answer:
Add all of the angles, and it should equal 180°
60 + 75 + 45 = 180°
Correct!
