5. To determine the number of kids under the age of 5 in your neighborhood, you sit outside of
your apartment and count the number of kids under 5 that pass by between the hours of 7AM
and 8AM. Do you think this method will provide you with a representative random sample?
Explain your reasoning.

Answers

Answer 1

Answer:

It will not provide a representative random sample.

Step-by-step explanation:

This is because kids under five will only leave the house if they are going to the park or doing something with there parents. They don't go to school either so they most likely won't leave during the hours of 7 AM and 8 AM.

Hope this helps! :D

1. Multiply the numerator and the denominator by the complex conjugate of the denominator.

2. Simplify the results into the real part and the imaginary part.

Divide the complex numbers. Show all work.

Answers

Answer:

Step-by-step explanation:

hello : given z =  (-6-10i)/(4+7i)

the complex conjugate of the denominator is : 4-7i

1. Multiply the numerator and the denominator by the complex conjugate of the denominator:  z =  (-6-10i)(4-7i)/(4+7i)(4-7i)

use identity : (a + b)(a - b) = a² - b² calculate the product : (4+7i)(4-7i)

(4+7i)(4-7i) = 4² -(7i)² =16 -49i² =16+49 = 65..... ( i² = -1)

2) Simplify the results calculate the numerator :  (-6-10i)(4-7i)

(-6-10i)(4-7i)  = -24+42i -40i+70i²   = -24+42i -40i-70 .....( i² = -1)

(-6-10i)(4-7i) = -94+2i

now :  z =  (-94+2i )/65  = (-94/65) +(2/65) i

   the real part is :   ( -94/65) and the imaginary part is : 2/65

1/13

Lu is making a quilt that is 20 squares wide and has 15 rows. The border of the quilt is made by using each toy design equally as often. There are a total of 6 toy designs. Each square can hold one design. How many of each design does she use for the border?

Answers

Answer:

Out of 6 designs 4  designs will have 12 repetitions and 2 designs will have 11 repetitions.

Or

On the average each design will be repeated 11.67 times.

Step-by-step explanation:

HEre the width = 20 and length = 15

The perimeter = 2(l+b)

                         = 2( 20+ 15) = 70

The border of the quilt has 70 squares. Each square can have 1 design and there are 6 designs

Number of repetitions for each design = 70/6= 11. 67

6 designs can have 11 repetitions for 66 boxes=  6 *11= 66

4 squares will be left out. 70-66= 4

4  design can have  additional repetition.

Meaning out of 6 designs 4  designs will have 12 repetitions and 2 designs will have 11 repetitions.

Or

On the average each design will be repeated 11.67 times.

In the following diagram, medians AD and BE intersect at F. Which of the following segments would not be true

1) ECD~ACB
2) EF= 1/2EB
3) ED||AB
4) the median drawn from C would pass through F

Answers

Answer is number 1 you welcome

The segment that is false is (2) EF= 1/2EB

The median lines of a triangle always meet at a point.

This means that the line from point C is true (option 4 is true)

The median divides the side lengths of the triangle into equal segments.

However, the centroid at point F do not divide line EB into equal segments

This means that:

The equation EF= 1/2EB is false

Hence, the segment that is false is (2) EF= 1/2EB

If you have a new deck of shuffled cards, what is the probability you will choose an ace? (52 cards, no jokers) A) 1 13 B) 1 2 C) 1 4 D) 1 6

Answers

Answer:

B 1/2

Step-by-step explanation:

I looked it up.

But I think it'd be C because there would be 4 aces in the deck, and C has 1/4

Answer: 1/13 is the correct answer.

Step-by-step explanation: You put the total amount of aces, which is four, on the top part of your fraction and the total number of 52 cards on the bottom of your fraction. Since four will divide into both numbers, you simplify 4/52 to get 1/13. 4 divided by four is one. 52 divided by 4 is 13. That is how you get your 1/13 from 4/52. Answer was confirmed correct on the test I took. I hope this helps you! Thanks!

Answer:

  C

Step-by-step explanation:

Both inequalities have y ≤ ( ), so will be bounded by solid lines, and shaded below that line (where y-values are lower). The first inequality has a boundary line with a steeply negative slope; the second has a shallow positive slope.

Since both are shaded below, the doubly-shaded area (AB) will be in the bottom quadrant, below the point of intersection of the lines. The graph attached below shows the correct shading.

There are 240 girls at the park. There are 360 more boys than girls at the park.How many boys are at the park?

Answers

Answer:

600 boys

Step-by-step explanation:

To find how many boys are at the park, add 360 to 240:

240 + 360

= 600

So, there are 600 boys at the park

Answer:

There are 600 boys at the park.

Step-by-step explanation:

The information we know is that there are already 240 girls at the park, and we also know that there are 360 more boys than girls. So to find out how many boys there are we must add the two values together, 240 and 360.

240 + 360 = 600

So that means there are 600 boys at the park.
