By using the 20 percent off coupon that she found in the newspaper, Jill saved $4 on the extra large bag of dog food that she bought. what was the cost of the dog food without the coupon?

Answers

The cost of the dog food without the coupon is $20.

What is the percentage?

The Percentage is defined as representing any number with respect to 100. It is denoted by the sign %.

It is given that 4 dollars are 20% of the original price of the dog food. Let's have x be the original price of the dog food.

The cost of the dog food without the coupon is calculated as:-

4=x ( 20 )

To get x alone divide both sides by 20 and solve further.

( 4 / 20 )= ( x ( 20) / 20 )

Solve the above equation by cancelling 20 to get the value of x.

4/20=x

Divide 4 by 20 to get the answer and multiply by the value 100 to get the actual cost of the product.

x = 0.2 x 100 = 20

Therefore, the cost of the dog food without the coupon is $20.

well if 20% x 5 is 100%
then $4 x 5 = $20
So without the coupon the dog food costs $20

A card is drawn at random from a well-shuffled deck of playing cards. Find the probability that the card drawn is (i)a card of spade or an ace (ii)a red king (iii)neither a king nor a queen (iv)either a king or queen.Thank you.

Answers

There are 52 cards in a standard deck so that would be the whole in the part/whole equation so
i... There are 13 spade cards and then 3 other aces since there are 4 suits of cards so 16/52 or about 0.30769 or 30.8% rounded

ii....There are 2 reds of each card in a standard deck along with 2 blacks so there would be 2 red kings which would be a 2/52 chance or about 0.0384 or 3.8% rounded

iii.... There are 4 kings and 4 queens in each deck so (52-8)/52 which is a 44/52 chance, 0.8461 about, or 84.6% rounded

iv..., As I said in iii, there are 8 kings and queens so an 8/52 chance, about 0.1538, or 15.4% rounded

13r2(2rs + 4r3 – 3s4)
13r2(26r3s + 52r5 – 39r2s4)

Answers

Answer:

Option 3rd is correct

$13r^2(2rs+4r^3-3s^4)$

Step-by-step explanation:

GCF (Greatest common factor) is the largest number that divides the two number.

Factor $26r^3s+52r^5-39r^2s^4$

Find the GCF of the given expression.

GCF of $26r^3s$ , $52r^5$ and $39r^2s^4$ is, $13r^2$

then;

$13r^2(2rs+4r^3-3s^4)$

Therefore, the resulting expression is, $13r^2(2rs+4r^3-3s^4)$

Answer:

The Given Expression is

→ $26r^3s + 52r^5 -39r^2s^4\n13* 2* r* r^2 * s + 13* 2* 2* r^2* r^2* r- 13 * 3* r^2* s * s^3\n\n\text{Taking out common factors}\n\n13r^2(2 rs + 2* 2 r^3 -3 s^4)\n\n13r^2(2 r s+ 4 r^3 - 3 s^4)$

Option $<strong>13r^2(2 rs + 4 r^3 - 3 s^4)$ is correct option.

What is arithmetic?

Arithmetic is the branch of mathematics that deals with the study of numbers using various operations on them. Basic operations of math are addition, subtraction, multiplication and division. These operations are denoted by the given symbols.

Given:

According to given question we have,

Let the number be x.

1/11w - 12

1/11w-12=0

Add 12 both sides we get,

1/11w-12+12=0+12

1/11w=12

w = 132

Therefore, the required number is 132.

Let w be the number.

1/11w - 12

1/11w-12=0

1/11w-12+12=0+12

1/11w=12

1/11w÷1/11=12÷1/11

w = 132

Therefore, the equation would be 1/11w - 12 and the value of w is 132.

A comic-strip writer churns out a different number of comic strips each day. For 16 days, the writer logged the number of comic strips written each day (sorted low to high): {1, 1, 2, 2, 2, 3, 3, 3, 3, 4, 4, 4, 5, 5, 6, 7}. If the writer writes for one more day and comes up with 8 new comic strips, how will the skew be affected?A) The distribution will be skewed to the negative side.

B) The distribution will be skewed to the positive side.

C) The distribution will have the same mean and median.

D) The distribution will have a mean lower than the median.

Answers

The distribution will be skewed to the positive side, the correct option is B.

What is mean?

Mean is the average of the data set obtained by summing all the values of the data set and then dividing it by the number of data in the set.

The data of the comic strips written is

{1, 1, 2, 2, 2, 3, 3, 3, 3, 4, 4, 4, 5, 5, 6, 7}

Mean = 54/16

Mean = 3.375

Median = 3

When 8 is added to the data

Mean = 3.64

Median = 3

The Mean > Median, so the distribution will be skewed to the positive side.
