Urgent!! thankyou so much for answering when u do.

Answer:

Independent - Minutes

Dependent - Push up #

Step-by-step explanation:

The minutes do not depend on anything so they would be independent. The push ups depend on how many minutes there are so it is dependent.

Hope this helps :)

Answer:

A = (b1 + b2)h/2

Step-by-step explanation:

The shape given is a trapezoid having two parallel sides which can be labelled b1 and b2 respectively. The distance between the two parallel sides is the height of the trapezoid, which is labelled h.

Area of a trapezoid is given as:

A = (b1 + b2)h/2

Answer:

Step-by-step explanation:

It is helpful to remember that opposite angles of an inscribed quadrilateral are supplementary. This lets you find the value of m.

  ∠A +∠K = 180°

  8m° +10m° = 180°

  18m = 180

  m = 180/18 = 10

Using this value we can find ...

  ∠H = 5m° = 5·10° = 50°

  ∠A = 8m° = 8·10° = 80°

  ∠W = 180° -∠H = 180° -50° = 130°

Answer: 25

Step-by-step explanation:

From the question, we are informed that the piece of rural land sold ten years ago for 40000 and that the price for the same land this year is $800 more per acre, and it sold for 60000.

The size of the piece of land in acres will then be:

40000 + 800x = 60000

800x = 60000 - 40000

800x = 20000

x = 20000/800

x = 25

The land is 25 acres

Answer: 25

Step-by-step explanation:

40000 + 800x = 60000800x = 60000 - 40000800x = 20000x = 20000/800x = 25

Answer:

$50

Step-by-step explanation:

Given data

We are given that the price is $40

the markup percent is 25%

Hence the price will be

40+25% of 40

=40+ 25/100*40

=40+ 0.25*40

=40+10

=$50

Therefore, the price of the dress is $50

Answer:

Step-by-step explanation:

(a) The length and breadth of the playground as measured by the surveyor are 20 m and 13 m respectively to nearest metre.

Since the actual length is x m and breadth is y m, then;

i.               x ≥ 20 m or x ≤ 20 m

ii.              y ≥ 13 m or y ≤ 13 m

(b) perimeter of the playground = 2 (length + breadth)

                                                     = 2 ( 20 + 13)

                                                     = 2 x 33

                                                     = 66 m

The range of values of the perimeter = 65.4 m < perimeter < 66.5 m

ii. area of the playground = length x breadth

                                          = 20 x 13

                                         = 260 [tex]m^{2}[/tex]

The range of values of the area = 259.4 [tex]m^{2}[/tex] < Area <  260.5 [tex]m^{2}[/tex]

Answer:

0.73

Step-by-step explanation:

Number of cards in a standard deck = 52

Number of black cards = 26

Number of face cards = 12

Probability of drawing either a black or face card

Probability = required outcome / Total possible outcomes

P(drawing a black card or face card) = (number of black cards / total card) + (number of face cards / total cards)

= 26/52 + 12 /52

= 0.5 + 0.2307692

= 0.73

Answer:

the circumference of this circle is approximately 25.12 cm with π as 3.14.

Step-by-step explanation:

circumference of a circle is technically a perimeter of a circle.

we find the circumference of a circle by using the following formula :

c = 2πr                                   or                                 c = πd

r represents the radius                                             d represents the diameter

since 4 yds here is a radius, we use the left formula i placed above. then, we substitute the numbers in. pi represents 3.14 as said in your question. even if you use 22/7, you will still get around the same result.

c = 2πr

c = 2(3.14)4

c = 6.28(4)

c = 25.12 yds

therefore, the circumference of this circle is approximately 25.12 yds.

Answer:

Sphere volume is this formula

V=(4/3)πr^3

plug in 21 for r in this formula

If you are meant to round pi to 3.14 the answer is = 38722.72

If you are not meant to round pi to 3.14 the answer is = 38792.39

Answer:

Answer:

Step-by-step explanation:

The midpoint is just the average coordinates of the endpoints.

mp=((x1+x2)/2, (y1+y2)/2), we have points (6,4) and (5,-2)

mp=((6+5)/2, (4-2)/2)

mp=(5.5, 1)

So D is the answer.

Answer:

The answer is below

Step-by-step explanation:

Shoppers at a mall have a mean weight of 70 kg with a standard deviation of 10 kg. An elevator at the mall holds a maximum of 6 people, and safety engineers are curious about the average weight of shoppers on a full elevator. Suppose that we take random samples of 6 shoppers and calculate the mean weight x ˉ  on top of the shoppers in each sample.

Solution:

Let variable x represent the weight of a shopper at the mall.

Assuming this variable has a normal distribution with mean μ= 70kg and standard deviation σ = 10kg.  

There are random samples of 6 shoppers. That is sample size (n) = 6  

The mean of the sample (μₓ) is the same as the mean of the population (μ), hence:

μₓ = μ = 70 kg

The standard deviation of the sample (σₓ) is equal to the standard deviation of the population (σ) divided by the square root of the sample size (n).. Hence:

σₓ = σ / √n = 10 / √6 = 4.08 kg

Answer:

Mean: 70

Standard Deviation: 4.1
