Answer:
767
Step-by-step explanation:
The probability that the sample proportion is less than 0.55 is approximately 0.1569.
To calculate the probability that the sample proportion is less than 0.55, we can use the normal approximation to the binomial distribution, assuming the sample size is large enough (n > 30) and the conditions for using the normal approximation are met.
Given:
Sample size (n) = 100
Population proportion (P) = 0.60
Sample proportion (p) = 0.55
To apply the normal approximation, we need to calculate the mean (μ) and the standard deviation (σ) of the sampling distribution.
Mean (μ) = P = 0.60
Standard Deviation (σ) = sqrt((P * (1 - P)) / n)
σ = sqrt((0.60 * (1 - 0.60)) / 100)
σ ≈ 0.04899
Next, we can calculate the z-score using the formula:
z = (x - μ) / σ
where x is the desired sample proportion.
For a sample proportion of 0.55, we have:
z = (0.55 - 0.60) / 0.04899 ≈ -1.020
Using a standard normal distribution table or a calculator, we can find the area to the left of the z-score (less than -1.020). The area represents the probability.
P(z < -1.020) ≈ 0.1569
Rounding to four decimal places, the probability that the sample proportion is less than 0.55 is approximately 0.1569.

-3.5 ℉
5 ℉
1.5 ℉
-0.5 ℉
-2℉,
2.5℉
-4 ℉
Part 1: Weather Analysis
1. Plot and label the temperatures on a number line. You can create it by using a drawing program, by drawing it by hand and sending in a picture, or by describing in detail how the completed number line should look.
2. Compare the weather on two different days using an inequality. Then see if their comparisons change by finding the absolute value of each.
Day 1: Day 2: Comparison of Day 1 and Day 2: ____ < _____ or _____ > _______ Comparison of days with absolute value: ____ < _____ or _____ > _______
3. Which temperature during the week is the closest to 0? Explain how you decided this using absolute value.

Answer:
1. 6 2. -5
Step-by-step explanation:
On negatives you add.
Answer:
6 for the first one, then -5 for the next one
Step-by-step explanation:
alright, first one.
starts from 0 on a number line and hops 4 right, add 4. [ positive is right, negative is left ]
0 + 4 = 4
coming from 4, to 6 on the left, so either add -6 or subtract 6, both work either way.
4 + (-6) = -2
finally, we land up on -2, and then 8 units to the right once again, which would be adding 8.
-2 + 8 = 6
so that would be 6.
second one, inverse means opposite. so they're asking for the opposite of positive 5, which is negative 5. (-5)

What is 12 1/2% less than $80? I hope you're havin' a good day.
Answer:
10
12.5% less than 80 = 10
Step-by-step explanation:
Step 1: Our output value is 80.
Step 2: We represent the unknown value with x.
Step 3: From step 1 above, 80=100%
Step 4: Similarly, x=12.5%
Answer:
70
Step-by-step explanation:
To answer this question, we have to find out what is 12 1/2% of 80 and subtract it from 80. 12 1/2% is the same as 0.125, or 1/8. 1/8 of 80 is
1/8 * 80 = 10, 80 - 10 = 70
A drawing of a sailboat was made useing a restangle and two right triangles, as shown. what is the area of the drawing f the sailboat in square centimeters
Answer:
45 centimeters squared (45 square centimeters - same thing)
Explanation:
First we need the area of each shape
To find the area of a right triangle we multiply the length of the legs and then divide by 2 - ab/2
Triangle 1: 6 centimeters squared
Triangle 2: 9 centimeters squared
To find the area of a rectangle you multiply the length by the width - lw
Rectangle: 30 centimeters squared
Now we add the values together:
6 + 9 + 30 = 45 centimeters squared

=> You can convert mixed fractions into improper fractions by the following steps so it's easier to solve the equation:
Multiply the denominator of the mixed fraction by the whole number given on the left of the fraction. Add the number you get by the numerator of the fraction and, the answer you get will be your numerator for the improper fraction, keep the denominator similar to what it was in the mixed fraction.=> [tex]1\frac{1}{2}[/tex] would be [tex]\frac{3}{2}[/tex] as an improper fraction; [tex]3\frac{1}{2}[/tex] would be [tex]\frac{7}{2}[/tex] as an improper fraction. Whereas 4 would remain the same since it's a whole number.
=> Now, multiple everything together: ([tex]\frac{3}{2}[/tex]) * (4) * ([tex]\frac{7}{2}[/tex])
The answer would be 21!

Take both values and add them over 2
Receive the answer 4.5
Add that to the rectangle values for an answer of 31.5
Hope this helps
Have a good day
Answer:
31.5
Step-by-step explanation:
so first find the area of the triangle, which is 9. then divide that by 2 which equals 4.5.
now find the area of the missing square, which is 5×4, and that equals 20. now pretend that the square is whole, and find the area of the whole square. that would be 8×7, which equals 56. so now you need to subtract 4.5 and 20 from 56.
56
