Answer:
0.5137
Step-by-step explanation:
The margin of error equals the critical value times the standard error.
MoE = CV × SE
In this case, the critical value is the z-score.
For a proportion, the standard error is:
SE = √(pq/n)
SE = √(0.75 × 0.25 / 101)
SE = 0.04309
Therefore:
0.03 = z × 0.04309
z = 0.6963
So the probability is:
P(-0.6963 < Z < 0.6963)
= P(Z < 0.6963) − P(Z < -0.6963)
= 0.7569 − 0.2431
= 0.5137

What are the differences between chart and tabular forms?A chart is one that displays data using symbols such as bars in a bar chart, columns in a line chart, or slices in a pie chart. A chart can represent tabular numerical data, functions, or specific types of quality structures to convey a variety of information.Using a tabular form and a single page, users can change multiple rows and columns in a table at the same time.A chart displays data in the form of a table, graph, or diagram. It can convey vast amounts of information in a variety of ways.As the cost per pack is C=1.75b. C is the Cost in dollars.
3 × 1.75 = 5.25
6 × 1.75 = 10.5
9 × 1.75 = 15.75

) How many miles can the SUV travel on
25 gallons of gas?
miles
Answer: 1,000
Step-by-step explanation: after you find the answer for 20/3 divided by 1/6 equals 40 so you multiply 40 x 25 to get 1,000
The SUV can travel 425 miles on 25 gallons of gas.
What is a proportion?A proportion is an equation that sets two ratios at the same value.
We can use a proportion to solve this problem. The miles per gallon (mpg) of the SUV can be calculated by dividing the distance traveled by the amount of gas used:
MPG = distance/gas
So for the first case, we have:
MPG = 340 miles / 20 gallons = 17 miles per gallon
To find out how far the SUV can travel on 25 gallons of gas, we can use the same mpg and solve for the distance:
Distance = mpg x gas
Distance = 17 miles per gallon x 25 gallons
Distance = 425 miles
Therefore, the SUV can travel 425 miles on 25 gallons of gas.

x = -0.2533*20 + 400 = 394.93
In an isosceles triangle the length of the legs is 8 cm and the angle between them is 150°. Find the altitude to the legs and the area of the triangle.
Find AH and Aᴬᴮᶜ
Answer:
AH = 4 units
Area of ΔABC = 16 square units
Step-by-step explanation:
Since ΔABC is an isosceles triangle,
AC = BC
∠CAB ≅ ∠ABC [Opposite angles of the equal sides in a triangle are equal]
In ΔABC,
m∠CAB + m∠ABC + m∠ACB = 180°
m∠ABC + m∠ABC + 150° = 180°
2m∠ABC = 30°
m∠ABC = 15°
Now we apply cosine rule in ΔABC,
AB² = AC² + BC² - 2(AB)(BC)cos(m∠ACB)
AB² = 8² + 8² - 2(8)(8)cos(150°)
AB² = 128 + 110.85
AB = [tex]\sqrt{238.85}[/tex]
AB = 15.45
In ΔABH,
sin(m∠ABH) = [tex]\frac{AH}{AB}[/tex]
sin(15°) = [tex]\frac{AH}{15.45}[/tex]
AH = 15.45sin(15°)
AH = 3.998
AH ≈ 4.0 units
HC = [tex]\sqrt{8^{2}-4^2}[/tex]
= [tex]\sqrt{48}[/tex]
= 6.93
Area of the triangle ABC = [tex]\frac{1}{2}(BC)(AH)[/tex]
= [tex]\frac{1}{2}(8)(4)[/tex]
= 16 square units

How do you calculate the percentage of a number? ex. 70% of 70
Answer:
Find P percent of X
Find what percent of X is Y
Find X if P percent of it is Y
Step-by-step explanation:
Example: What is 10% of 150?
Convert the problem to an equation using the percentage formula: P% * X = Y
P is 10%, X is 150, so the equation is 10% * 150 = Y
Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10
Substitute 0.10 for 10% in the equation: 10% * 150 = Y becomes 0.10 * 150 = Y
Do the math: 0.10 * 150 = 15
Y = 15
So 10% of 150 is 15
Double check your answer with the original question: What is 10% of 150? Multiply 0.10 * 150 = 15

Answer:
kkkkk
Step-by-step explanation:
kkkkkk kkkkkk kkkWhy were the Punic War so important for the development of the Roman Empire?
Answer:
20
Step-by-step explanation:
If you have 60,000,000 barrels of crude oil and 34% of the barrels are gasoline then you have to set up the problem like this because you have to find out how much 34% of 60,000,000 is first in order to solve the problem.
is/of x 100/%
60,000,000 / a X 100 / 34
so..60,000,000 x 34 = 2,040,000,000
then divide that amount by 100= 2,040,000,000 / 100 = 20, 400,000
so the 34% actually is the total 20,400,000. Now, you divide the dollar amount 408,000,000 million barrels by the total amount of gasoline which is 20,400,000.
408,000,000 / 20,400,000 = 20
So each barrel of gasoline cost $20.

[tex]x + 2 = - 12[/tex]
Subtract sides 2
[tex]x + 2 - 2 = - 12 - 2[/tex]
