It is enough for him to use a simple random sample of 172 cars.

It is required that there are at least 10 successes and 10 failures to test a hypothesis that involves a proportion p in a sample of size n.

Following conditions are required for it:

1) np ≥ 10

2) n (1-p) ≥ 10

p = 6% = 0.06

n = 172

So, there are at least 10 successes and 10 failures in the 172 cars sample, it is enough for him to use a simple random sample of 172 cars.

For the angles, we have;

P(B) such that a and b are mutually exclusive is 0.23

A group of potential results from a specific experiment is an event. Events that do not take place at the same time are said to be mutually exclusive. For instance, if a coin is tossed, the outcome will either be head or tail; we cannot obtain both outcomes. Since they do not occur at the same time, such occurrences are also known as disjunct events.

Given: P(A) =0.28

P(AUB) = 0.51

We know,

P(AUB) = P(A) + P(B) - P(A∩B)

Since A and B are mutually exclusive events, they cannot happen together.

So, P(A∩B) = 0

Then,

P(AUB) = P(A) + P(B)

0.51 = 0.28+ P(B)

P(B) = 0.51 - 0.28 = 0.23.

Hence, P(B) = 0.23

1) an integer and a rational number

Explanation:

1) -√64 = -4

This is an integer.

Integers include natural numbers, the opposites of this numbers and zero.

-4 is a negative number and the opposite of the natural number 4

Hence -4 is an integer.

-4 can be written as a fraction:

-4 = -4/1

Hence, it is also a rational number

Based on the number of inches in the drawing and the number of feet in real life, the scale that Paula used was 3 inches = 2 feet

The scale that Paula used was such that the stage was 56 feet long in real life but 84 inches long on the drawing.

The scale can therefore be shown by the ratio:

56 feet : 84 inches

If the number of inches is 3 then the number of feet in the scale would be:

56 feet : 84 inches

x feet    :  3 inches

Cross-multiplying gives:

84x = 168

x = 168 / 84

x = 2 feet

Answer:

b x 8 = 40 and 40 / 8 =b

Step-by-step explanation:

well, 8 charms makes one bracelet, so add up 8 until you run out of charms:

We only have 40 charms, so we can make 5 bracelets!

Now, plug this number (5) back into the equations:

b x 8 = 40

(5) x 8 = 40

40 = 40

this checks out!

40 - 8 = b

40 - 8 = (5)

32 = 5

32 does not equal 5, so this equation doesn't work.

40 / 8 = b

40 / 8 = (5)

5 = 5

This equation works :)

b + 8 = 40

(5) + 8 = 40

13 = 40

13 does not equal 40, so this is also a bad equation..

since b x 8 = 40 and 40 / 8 = b both produced the right results, we know those two are our answers!

It is to be noted that by the proof given below, the attached shape ABCD is a kite.

A kite is a quadrilateral having reflection symmetry across a diagonal in Euclidean geometry. A kite has two equivalent angles and two pairs of adjacent equal-length sides as a result of its symmetry.

The proof is as follows:

AB = AD [Given]

∠ADC = 115°   [Angles on a Straight line]

That is 180 - 65 = 115°

∠BCD = 20°    [Vertical Angles are equal]

∠ABC = (360 - (20+115+110))

= 115°              [Angles in a quadrilateral]

STEP BY STEP EXPLANATION:

We can see that XW segment divides the YZ side into two equal parts, which measure 15 units. And we can also see that the XW segment starts in one of the vertex of the triangles and goes to the opposite side.

Then, we can analyze the definition for the median of a triangle

Finally, if we compare, we can see that the definition of median describes the XW segment.

ANSWER:

Answer:

35000

Step-by-step explanation:

So the number is 34582

now look at the hundreds

if it is 5 or over then we add a thousand to and subtract what ever the lower than thosand

and in this case it is 5 so we round UP

and now we have 35000

The answer is 35,000.

To round to the nearest thousand, we look at the last three digits. If these digits are 500 or greater, then we round the thousands digit up, and if they are less than 500, then we round down, keeping the thousand's digit the same.

Since in this case the last three digit consists of 582 which is greater than 500 so we round the thousands digit up i.e. from 4 to 5 in this case.

2A = πk² + 3t ( subtract 3t from both sides )

2A - 3t = πk² ( isolate k² by dividing both sides by π )

[tex]\frac{2A-3t}{\pi }[/tex] = k² ( take square root of both sides )
