Q6. Yesterday Aaron ran 5 km. This morning Aaron ran 4 km. How far did Aaron run altogether?

How many different rectangles can you draw with a perimeter of 60cm.

sineoko [7]

Answer:

infinitely many

Step-by-step explanation:

i can have a rectangle whose length is extremely close to 0 (ie 1 X 10⁻⁴⁴⁴⁴⁴⁴⁴⁴)

and have an extremely wide width. But it's still a rectangle that has perimeter 60.

Prime factorization of 891

Fantom [35]

So exg
prime factorization is finding the prime number that will multiply to getthat tnumber
normally we exclude the number 1
so prime factor of 6=2 times 3
note:2*3 menas 2 times 3

so 891
it is odd so not divisible by 2
try 3
891/3=297
3*297=891
factor further
297
try 3
297/3=99
3*3*99=891
99
divide by 3
33
3*3*3*33
33
divide by 3
11
3*3*3*3*11
11 is prime so the prime factoization is
3*3*3*3*11 or 3^4*11

A book can be classified as either non dash fiction or fiction. Suppose that 87% of books are classified as fiction. (a) Two b

Mnenie [13.5K]

Answer:

0.7569, 0.5729,0.4371

Step-by-step explanation:

Given that the books are of only two types either non dash fiction or fiction.

Also probability of selecting a fiction = 0.87 = p

X - no of books fiction selected is binomial with p = 0.87 and n =2

(since each trial is independent of the other and there are only two trials)

a) the probability that both books are fiction=

$P(X=2) = 0.87^2 = \\0.7569$

b) Here n =4 with same p.

$P(X=4) =0.87^4 \\= 0.5729$

c) Prob atleast one is non dash fiction = $P(X< 4)\\= 1-P(X=4)\\=1-0.87^4\\=0.4371$

This is not unusual since 0.4371 probability is not nearer to 0 it is almost half.

1 2 3 4 5 6 7 8 9 10 11

alexandr402 [8]

1) PEMDAS: 12 * 5 + 6 / 6

12 * 5 = 60

60 + 6 / 6

6 / 6 = 1

60 + 1 = 61

61 is the final answer.

2) Absolute Value: |-2 - 4| = -6 HOWEVER, because it is in the absolute value signs, it becomes 6. 6 - 4 = 2

2 in the final answer.

3) 4 + 4 + 2 = 10 Because they are all negatives, we add back the negative sign.

-10 is the final answer.

4) 15x + 1 = 26

Subtract 1 from each side.

15x = 25.

25/15 = 1.6...

x = 1.6...

5) 2x -4 + 3x = - 1

2x + 3x = 5x

5x - 4 = -1

Add 4 to each side

5x = 3

3/5 = 0.6

x = 0.6

6) x-2/3 = x+4/5

I don't remember the steps, but the answer is x = 11

7) Finding the relationship between x:4 and 5:20

20/5 = 4

x = 1

The smaller rectangle has a reduction of 5 times.

8) Mean is found by adding all the number, then dividing by the amount added.

18 + 27 + 15 + 24 + 18 + 26 + 19 + 24 = 171

171/8 = 21.375

Mean = 21.375

Median is found by putting the numbers in increasing order, then finding the middle number, 15, 18, 18, 19, 24, 24, 26, 27. 24 + 19 = 43. 43/2 = 21.5

Median = 21.5

9) Circumference of a circle = 2(pi)(r)

Circumference = 30πin (thats the pi symbol)

If you use the typical pi fill-in (3.14) the its 2 * 3.14 * r then it would = 94.5in.

10) Combing Like Terms: 5x + 7y - 8y^2 + 2x - y

5x + 2x = 7x

7x + 7y - 8y^2 - y

-y + 7y = 6y

Answer: -8y^2 + 7x + 6y

Artyom0805 [142]

Answer:

The classification of the set of circumstances is presented in the following subsections of the understanding.

Step-by-step explanation:

A 7-year health research project revealed that individuals for whom the mom took DES throughout pregnancy seem to have been twice as probable as women for whom the mothers didn't use the medication to establish tissue irregularities that could cause cancer.

(a)

Women with whom the mothers have taken DES throughout pregnancy as well as women where its mothers haven't taken DES during pregnancy.

(b)

The information collected seems to have been a sample or survey.

(c)

A sampling unit of 3980 (women) showed that performance 63 industrialized tissue irregularities that could contribute to disease (cancer) in the proportion of females with whom the mom brought the powerful DES all through pregnancy.

The proportion of abnormalities in tissues established by females does seem to be:

= $\frac{63}{3980}$

= $0.015829$

Of every thousand women, 15.8 established tissue abnormalities.
