Answer:

10 bugs

Step-by-step explanation:

<h2><u>Percentages</u></h2>

last month the spider ate 8 bugs

it then ate 25% more bugs this month , meaning :

<em>100% was last month</em> ,

this <em>month its 100% + 25%</em> . (this is because it<em> increased by 25% more</em>)

we can make use of <u>cross multiplication</u> :

bugs : percentage

8 : 100

x : 125

100 x = 8 * 125

100x = 1000

x = 1000 / 100

x = 10

2.24 Exit poll: Edison Research gathered exit poll results from several sources for the Wisconsin recall election of Scott Walke

iVinArrow [24]

Answer:

0.4929 = 49.29% probability that he voted in favor of Scott Walker

Step-by-step explanation:

Bayes Theorem:

Two events, A and B.

$P(B|A) = \frac{P(B)*P(A|B)}{P(A)}$

In which P(B|A) is the probability of B happening when A has happened and P(A|B) is the probability of A happening when B has happened.

In this question:

Event A: Having a college degree.

Event B: Voting for Scott Walker.

They found that 57% of the respondents voted in favor of Scott Walker.

This means that $P(B) = 0.57$

Additionally, they estimated that of those who did vote in favor for Scott Walker, 33% had a college degree

This means that $P(A|B) = 0.33$

Probability of having a college degree.

33% of those who voted for Scott Walker(57%).

45% of those who voted against Scott Walker(100 - 57 = 43%). So

$P(A) = 0.33*0.57 + 0.45*0.43 = 0.3816$

What is the probability that he voted in favor of Scott Walker?

$P(B|A) = \frac{0.57*0.33}{0.3816} = 0.4929$

0.4929 = 49.29% probability that he voted in favor of Scott Walker

Can someone give me work for the estimate

If a rational number after dot "like 5.52") is smaller than 5(half) , then you assume the first number before that dot stuff :p
For example:

-》11,2 =11
-》 4.19= 4
-》2,2 = 2
etc

But if it's bigger than 5 or equals 5 , u assume the first number before that dot stuff +1
For example :
-》5.5 =6
-》3.9=4
-》225.7= 226
etcetc

so the answer is:;;

5.52 --》 52 is bigger than a half (50) so ur gonna assume like 6

1,6 --》(it equals with 1.60 too)
6 is bigger than 5 so ur gonna assume 2

6÷2 =3

Hope it helps! :))

The owner of two hotels is ordering towels. He bought 38 hand towels and 31 bath towels for his hotel in Arcadia, spending a tot

ololo11 [35]

Answer:

Cost of the hand towels is $2 and cost of the bath towels is $7 .

Step-by-step explanation:

Let us assume that the cost of hand towels be x .

Let us assume that the cost of bath towels be y .

As given

The owner of two hotels is ordering towels.

He bought 38 hand towels and 31 bath towels for his hotel in Arcadia, spending a total of $293.

Than the equation becomes

38x + 31y = 293

As given

He also ordered 45 hand towels and 71 bath towels for his hotel in Middletown, spending $587.

Than the equation becomes

45x + 71y =587

Multiply the equation 45x + 71y =587 by 31 .

45x × 31 + 71y × 31 = 587 × 31

1395x + 2201y = 18197

Multiply 38x + 31y = 293 by 71.

71 × 38x + 71 × 31y = 293 × 71

2698x + 2201y = 20803

Thus two equations are

1395x + 2201y = 18197

2698x + 2201y = 20803

Subtracting 1395x + 2201y = 18197 form 2698x + 2201y = 20803 .

2698x - 1395x + 2201y - 2201y = 20803 - 18197

1303x = 2606

$x = \frac{2606}{1303}$

x =$ 2

Putting this x = 2 in the equations

1395 × 2 + 2201y = 18197

2790 + 2201y = 18197

2201y = 15407

$y = \frac{15407}{2201}$

y = $7

Therefore the cost of the hand towels is $2 and cost of the bath towels is $7 .

Lamont Gatling purchased a phone answering system for his home office. The list price was $99.86. He also purchased a 12-foot ha

Natali5045456 [20]

Answer:

$130.7086

Step-by-step explanation:

List price of phone answering system = $99.86

Handset cord = $8.95

Telephone wire = 45 cent/foot ; length = 50 feet

Rebate on phone system = $5

Store coupon =$1 of each accessory

Sales tax = 6% on final price

Price before coupon = (99.86 + 8.95 + (50*0.45)) =$131. 31

Number of accessories = 3

Total coupon = $5 + ($1 * 3) = $8

Price after coupon = final price : $131.31 - $8 = $123.31

Sales tax = 0.06 * $123.31 = $7.3986

Amount paid = $123.31 + $7.3986 = $130.7086
