ANSWER

A, C, D

EXPLANATION

The center of the the given ellipse is the middle dot( The point in the middle of the oval shape).

Reading from the graph the center is (2,-1) because each box is 1 unit.

Hence,

A)The center is located at (2, –1).

is a correct option.

The length of the major axis is the distance from one vertex to the other. In this case the length of the major axis is the distance from the bottom point to the upper point. Counting from the grid the length is 8 units.

The length of the minor axis is the distance between the co-vertices which is 6 units. (left to right point).

Hence option B is not correct.

C) is also a correct option because the vertices are 4 units above and below the center.

The foci are located along the vertical axis. They are √7 units above and below the center.

D)The foci are √7 units above and below the center is also correct.(If actually √7 is the missing information in this option)

Option E is false because the foci are NOT located along a horizontal line.

NB: We use the relation

to find the foci.

In this case:

The foci is

Answer from: Quest

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies

Answer from: Quest

One shot. if 60% of 10 is 6, then what is 70%? we know it would be seven (since 60% is mathematically 60/100, or 6/10, then 70% is 70/100, or 7/10) but we can check anyway using ratios: 6 : 60% = x : 70%*inverse multiplicationx * 60% = 6 * 70%*divide both sides by 60%x = (6 * 70%) / 60%x = 7and since he has made 6 shots already, he would need just one more to get 7 shots or 70%. if the explanation is too confusing, comment and i will try to

At the olympic games, many events have several rounds of competition. one of these events is the men's 100-meter backstroke. the upper dot plot shows the times (in seconds) of the top 8 finishers in the final round of the 2012 olympics. the lower dot plot shows the times of the same 8 swimmers, but in the semifinal round. which pieces of information can be gathered from these dot plots? (remember that lower swim times are faster.) choose all answers that apply: a: the swimmers had faster times on average in the final round. b: the times in the final round vary noticeably more than the times in the semifinal round. c: none of the above.
