The above question is asking us to check if the exponents are written in the correct way or not.Let us look at the options one by one.

1) The exponent denotes the number of time the letter or number is multiplied.We have six x which are multiplied so the exponent for x which is 6 is right .The exponent is written correct .

2)We have seven A which are multiplied and five B multiplied making the exponent of A as 7 and B as 5 .The exponents are written correct.

3)There are six b and six c .The exponent rule has been followed here that is we can keep bc inside parenthesis and make 6 as the exponent.

4)Here exponent for x,y,z all are 5. we can not remove the exponent of x and y .It is not following the exponent rule .

Option 4 is not true.

Suppose that the probability that a customer plans to make a purchase is 0.32. Suppose that the probability of responding to an

Elanso [62]

Answer:

0.6495

Step-by-step explanation:

This is question based on conditional probability

The probability that a customer plans to make a purchase = 0.32.

The probability that a customer plans not to make a purchase = 1 - 0.32

= 0.68

The probability of responding to an advertisement given that the customer plans to make a purchase = 0.63

The probability of responding to an advertisement given that a person does not plan to make a purchase = 0.16.

Given that a person responds to the advertisement, what is the probability that they plan to make a purchase is calculated as:

0.32 × 0.63/(0.32 × 0.63) + (0.16 × 0.68)

= 0.2016/ 0.2016 + 0.1088

= 0.2016/0.3104

= 0.6494845361

Approximately = 0.6495

Rewrite the equation by completing the square.<br> x^2 -4x =0

olasank [31]

Step-by-step explanation:

x² − 4x = 0

To complete the square, take half of the second coefficient, square it, then add the result to both sides.

(-4/2)² = 4

x² − 4x + 4 = 4

(x − 2)² = 4

x − 2 = ±2

x = 2 ± 2

x = 0 or 4

Convert the following metric units of weight. a. 40 centigrams to grams b. 53 milligrams to grams c. 0.54 grams to decigrams d.

liubo4ka [24]

Answer:

a) $0.4$ grams

b) $0.053$ grams

c) $5.4$ decigrams

d) $2300$ milligrams

Step-by-step explanation:

To convert centigrams to grams you have to divide by 100.

$40$ centigrams = $\frac{40}{100}$ grams

= $0.4$ grams

To convert milligrams to grams you have to divide by 1000.

$53$ milligrams = $\frac{53}{1000}$ grams

= $0.053$ grams

To convert grams to decigrams you have to multiply by 10.

$0.54$ grams = $0.54*10$ decigrams

= $5.4$ decigrams

To convert grams to milligrams you have to multiply by 1000.

$2.3$ grams = $2.3*1000$ milligrams

= $2300$ milligrams
