Hey there,

Question : Steven had 24 pineapples. He sold 6 of them. What fraction of the pineapples did he sell?

Answer :
6 / 24 ----> divide by 6

For a recent year, the following are the numbers of homicides that occurred each month in New York City: 38, 30, 46, 40, 46,

lubasha [3.4K]

Answer:

Each month is equally likely

Step-by-step explanation:

Given that for a recent year, the following are the numbers of homicides that occurred each month in New York City:

38, 30, 46, 40, 46, 49, 47, 50, 50, 42, 37, 37.

We have to check whether it is equally likely for each of the 12 months

Set Hypotheses as

H0: All months are equally likely

Ha: atleast two months are not equally likely

(Two tailed chisquare test at 5% significance level)

This is a test for chi square goodness of fit and so assuming H0 to be true

we divide the total equaly among 12 months as expected

Observed Expected Chi square

Jan 38 42.66666667 0.510416667

Feb 30 42.66666667 3.760416667

Mar 46 42.66666667 0.260416667

Apr 40 42.66666667 0.166666667

May 46 42.66666667 0.260416667

June 49 42.66666667 0.940104167

July 47 42.66666667 0.440104167

Aug 50 42.66666667 1.260416667

Sep 50 42.66666667 1.260416667

Oct 42 42.66666667 0.010416667

Nov 37 42.66666667 0.752604167

Dec 37 42.66666667 0.752604167

Total 512 512 10.375

df=11

p value = 0.497

Since p >0.05 our alpha we accept H0

Each month is equally likely

Please help ASAP I am in desperate need

Vlad1618 [11]

Answer:

x = 9

TH = 12

Step-by-step explanation:

since TM is half of HM, the equation is:

2(21 - x) = 3x - 3

42 - 2x = 3x - 3

45 = 5x

x = 9

TH = 21 - x

TH = 21 - 9

TH = 12

A bag contains 2 white marbles and 7 purple marbles. Two marbles are drawn at random. One marble is drawn and not replaced. Then

Masja [62]

A.
$\frac{7purple}{9total} * \frac{2white}{8total} \\ \frac{14}{72} \\ =0.194$
The denominator of the second number goes down one because you aren't replacing the initial marble pulled, making the amount of marbles in the bag go down, but not affecting the white count because you pulled a purple marble.
b.
$\frac{2white}{9total} * \frac{1white}{8total} \\ \frac{2}{72} \\ =0.278$
The same can be said about the denominator for this problem, but not the numerator. The numerator must go down one number as well, because you already chose one white marble, taking one of the white marbles out of the bag, leaving you with one solitary, white marble.
c.
Chance of selecting two purple marbles:
 $\frac{7purple}{9total} * \frac{6purple}{8total} \\ \frac{42}{72} \\ =0.583$
Chance of selecting two white marbles:
$\frac{2white}{9total} * \frac{1white}{8total} \\ \frac{2}{72} \\ =0.278$
Chance of selecting two purple vs. Chance of Selecting 2 white:
0.583>0.278.
It is more likely to select 2 purple marbles.

Hope this helps!

As part of a research project on student debt at TWU, a researcher interviewed a sample of 35 students that were chosen at rando

Inga [223]

Answer:

Option a is right

Step-by-step explanation:

Given that as part of a research project on student debt at TWU, a researcher interviewed a sample of 35 students that were chosen at random concerning their monthly credit card balance.

Sample average = 2573

Variance = 4252

Sample size = 35

STd deviation of X = $\sqrt{4252} \\=65.21$

Score of student selected at random X=1700

Corresponding Z score = $\frac{1700-2573}{65.201} \\=-13.38$

Rounding of we get Z score = -13.4

option a is right
