Answer:

A

Step-by-step explanation:

Part A, A. Kari, because the mean and median of her scores is, 84.5.

Part B, Jocely will see a greater increase overall as her previous average is less.

The three main methods for identifying the average value of a set of integers are mean, median, and mode.

Adding the numbers together and dividing the result by the total number of numbers in the list yields the arithmetic mean.

The middle value in a list that is arranged from smallest to greatest is called the median.

The value that appears the most frequently on the list is the mode.

From the given information, The average score of Jocelyn is,

= (86 + 87 + 95 + 72 + 78 + 80)/6.

= 83.

And Similarly, The average score Kari is,

= (88 + 78 + 93 + 81 + 75 + 91)/6.

= 84.5.

Therefore, Kari scores better overall.

If they both get 90% on their next math quiz Jocely will see a greater increase overall as her previous average is less.

Answer:

D.2.58

Step-by-step explanation:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1 - 0.99}{2} = 0.005[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].

That is z with a pvalue of [tex]1 - 0.005 = 0.995[/tex], so Z = 2.58.

The answer is given by option D.

Answer:

[tex]\frac{6\\}{25}[/tex]

Answer:

2/5 remaining

Step-by-step explanation:

If a job is 35 and 3/5 was completed, 3/5 of 35 = 21

That is 35 - 21 = 14

The fraction of the job remaining to be done will then be 14/35 = 2/5

Explanation:

611 or 6÷11=0.545454545....

The hundredth position is two positions to the right of the decimal point. For this problem it is the 4:

0.545454545....

To round to the nearest hundredth you must look at the digit in the position immediately to the right of the digit in the hundredth place, which is the 5 in the thousandth place:

0.545454545....

If the digit to the right is greater than or equal to 5 you add 1 to the digit you are rounding to and make everything to the right 0.

If the digit to the right is less than 5 you add keep the digit you are rounding to the same and make everything to the right 0.

In this problem the digit to the right is a 5 so we add 1 to the digit we are rounding to and make everything to the right 0.

0.545454545....=0.550000000....=0.55

Answer:

a = -30

d = -32 - (-30) = -2

n = 96

So, using A.P. formula-

Tn = a + (n-1) d

T96 = -30 + (96-1) -2

T96 = -30 + (95) -2

T96 = -30 - 190

T96 = -220

Answer:  15 units .

__________________________________________________

In this case, a square, the two sides of the square (forming a right triangle) are equal), and the "diagonal" forming is the hypotenuse of the right triangle.

In these cases, the measurements of the angles of the right triangle are "45, 45, 90" ; and the measurements of the sides are:  "a, a, a√2" ; in which "a√2" is the hypotenuse.

We are given:  "15√2" is the hypotenuse" ; and we are given that this is a right triangle of a square with a diagonal length (i.e. "hypotenuse" of "15√2" ; so the measure of the side of the "square" (and other two sides of the triangle formed) is:  15 units.   (i.e.,  15, 15, 15√2 ).
