The sum of 1/2 and 1/3 is?

Answer:

Hoover flew Spitfires in the United States Army Air Forces during World War II and was shot down in 1944 off the coast of France. He was held for over a year in a German POW camp before eventually escaping and flying to safety in a stolen enemy aircraft. He then worked as a United States Air Force and civilian test pilot after the war, flying chase for the Bell X-1 supersonic flight, and as a flight instructor for North American Aviation during the Korean War.

He is best known as an air show display pilot, who flew for nearly 50 years until his retirement in 1999.[1] Known as the "pilot's pilot", Hoover revolutionized modern aerobatic flying and has been described in many aviation circles as one of the greatest pilots of all time.

Answer:

x = 3

m<m = 114°

m<n = 66°

Step-by-step explanation:

✔️Opposite angles of a parallelogram are always congruent to each other.

Therefore:

m<m = 114°

m<n = 66°

✔️Opposite sides of a parallelogram are also congruent. This implies that:

7x - 3 = 4x + 6

Collect like terms

7x - 4x = 3 + 6

3x = 9

Divide both sides by 3

3x/3 = 9/3

x = 3

To construct confidence interval for difference in proportion ; the following conditions must be met :

1.) The selected samples must have been randomly chosen or selected from a larger population. This is essential in other to eliminate bias.

Each group of samples must be independently chosen. That is, the samples of bug customers chosen must be independent of the sample of small customers selected.

The population from which the samples are drawn must be considerably larger than the sample size. Sample size, n should be ≤ 10% of the population size.

Answer:

Circles

Step-by-step explanation:

Think of a soup can sitting on its base on a kitchen counter.  The counter is an example of a plane (through) parallel to the base.  The points where the can and counter intersect form a circle.  Put a book on top of the can.  Again, the plane of the book is parallel to the base and the book and can intersect in a circle.

The same thing would happen if you cut the can open with a plane anywhere in between the two mentioned above, but it would make a mess!

The answer is circles. If you cut this shape in half you will get two circles.

Answer:

Step-by-step explanation:

The chord and the segment between the centers form the diagonals of a kite with each pair of side being the radius of the circles.

As we know the long diagonal bisects the shorter one and they are perpendicular.

Using Pythagorean, lets find the distance between the center of a greater circle and the chord:

The distance from the center of smaller circle and the chord is:

Now using Pythagorean again, find the radius of the smaller circle:

Answer:

a) 0.9999 = 99.99% probability that a filled bag will weigh less than 49.5 kilograms

b) 0.0018 = 0.18% probability that a randomly sampled filled bag will weight between 48.5 and 51 kilograms.

c) 46.24 kilograms

d) The standard deviation would have to be of 3.41 kilograms.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set 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]

The Z-score 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. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Mean of 45 kilograms and a standard deviation of 1.2 kilograms.

This means that [tex]\mu = 45, \sigma = 1.2[/tex]

a. What is the probability that a filled bag will weigh less than 49.5 kilograms?

This is the pvalue of Z when X = 49.5. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{49.5 - 45}{1.2}[/tex]

[tex]Z = 3.75[/tex]

[tex]Z = 3.75[/tex] has a pvalue of 0.9999

0.9999 = 99.99% probability that a filled bag will weigh less than 49.5 kilograms

b. What is the probability that a randomly sampled filled bag will weight between 48.5 and 51 kilograms?

This is the pvalue of Z when X = 51 subtracted by the pvalue of Z when X = 48.5.

X = 51

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{51 - 45}{1.2}[/tex]

[tex]Z = 5[/tex]

[tex]Z = 5[/tex] has a pvalue of 1

X = 48.5

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{48.5 - 45}{1.2}[/tex]

[tex]Z = 2.92[/tex]

[tex]Z = 2.92[/tex] has a pvalue of 0.9982

1 - 0.9982 = 0.0018

0.0018 = 0.18% probability that a randomly sampled filled bag will weight between 48.5 and 51 kilograms.

c. What is the minimum weight a bag of dog food could be and remain in the top 15% of all bags filled?

This is the 100 - 15 = 85th percentile, which is X when Z has a pvalue of 0.85. So X when Z = 1.037

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]1.037 = \frac{X - 45}{1.2}[/tex]

[tex]X - 45 = 1.037*1.2[/tex]

[tex]X = 46.24[/tex]

46.24 kilograms.

d. CCI is unable to adjust the mean of the filling process. However, it is able to adjust the standard deviation of the filling process. What would the standard deviation need to be so that no more than 2% of all filled bags weigh more than 52 kilograms?

X = 52 would have to be the 100 - 2 = 98th percentile, which is X when Z has a pvalue of 0.98, so X when Z = 2.054. We would need to find the value of [tex]\sigma[/tex] for this.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]2.054 = \frac{52 - 45}{\sigma}[/tex]

[tex]2.054\sigma = 7[/tex]

[tex]\sigma = \frac{7}{2.054}[/tex]

[tex]\sigma = 3.41[/tex]

The standard deviation would have to be of 3.41 kilograms.

I disagree with Shannon's statement that 758−513=245 based on the reasoning provided.

An equation is a mathematical statement that shows that two expressions are equal. It consists of two sides separated by an equal sign (=). The expressions on both sides of the equal sign can contain variables, constants, coefficients, and mathematical operations such as addition, subtraction, multiplication, division, exponentiation, logarithms, etc.

Here,

While it is true that 7−5=2, 5−1=4, and 8−3=5, this reasoning only applies to the individual digits in each place value, not the numbers as a whole. To subtract the two mixed numbers 7 5/8 and 5 1/3, we need to find a common denominator first.

To subtract mixed numbers with unlike denominators, we follow these steps:

Convert each mixed number to an improper fraction.

Find a common denominator for the two fractions.

Subtract the numerators and write the result over the common denominator.

Simplify the result, if possible, by reducing the fraction to lowest terms or converting it back to a mixed number.

Let's apply these steps to the problem:

7 5/8 - 5 1/3

Step 1: Convert each mixed number to an improper fraction.

7 5/8 = (87 + 5)/8 = 59/8

5 1/3 = (35 + 1)/3 = 16/3

Step 2: Find a common denominator for the two fractions.

The least common multiple of 3 and 8 is 24, so we'll use 24 as the common denominator.

59/8 = (593)/(83) = 177/24

16/3 = (168)/(38) = 128/24

Step 3: Subtract the numerators and write the result over the common denominator.

177/24 - 128/24 = 49/24

Step 4: Simplify the result, if possible, by reducing the fraction to lowest terms or converting it back to a mixed number.

49/24 is already in its simplest form, so the final answer is 49/24.

Therefore, the correct result of 7 5/8 - 5 1/3 is 49/24, not 245.

Step-by-step explanation:

The missing numbers represent the slope/rate of change (m) and y-intercept (b) of the table of values given.

✔️Let's find slope (m) using any two given pairs of values, say (2, 9) and (4, 6):

Slope (m) = change in y/change in x

= (6 - 9)/(4 - 2)

= -3/2

m = -³/2

✔️Find b by substituting (x, y) = (2, 9), and m = -³/2 into y = mx + b

Thus,

9 = -³/2(2) + b

9 = -3 + b

9 + 3 = b

b = 12

The missing numbers are -³/2 and 12.

Step-by-step explanation:

If you divide the isosceles triangle into two right triangles, each has a leg and hypotenuse of 8 and 17, respectively. You may recognize these numbers as part of the Pythagorean triple (8, 15, 17). That recognition tells you the triangle's height is 15 m, so its area is ...

  A = 1/2bh

  A = 1/2(16 m)(15 m) = 120 m² . . . . triangle area

__

Alternate solutions

Given the three sides, you can find the smallest angle from the Law of Cosines. It will be ...

  α = arccos((17² +17² -16²)/(2·17·17)) ≈ 56.144°

Then the area is ...

  A = 1/2·ab·sin(C) . . . for triangle with sides a, b, c and opposite angles A, B, C

  A = 1/2sin(α)·17·17 = 120 . . . m²

__

Using Heron's formula:

  s = (17 +17 +16)/2 = 25

  A = √(25(25 -17)(25 -17)(25 -16)) = 5×8×3 = 120 . . . m²

If you need to, you can compute the triangle's height from the Pythagorean theorem.
