Drag the tiles to the correct boxes to complete the pairs. simplify the mathematical expressions to determine the product or quo

Sholpan [36]

The simplified mathematical expressions with the first factor to the nearest tenth are:

7.8 x 10

3.3 x $10^{3}$

2.1 x $10^{-3}$

3.7

<h3>What are the simplified mathematical expressions ?</h3>

Scientific notation is used to simplify large numbers in smaller numbers. In order to write a number in scientific notation , the number is written as a decimal number, between 1 and 10 and multiplied by a power of 10.

(8.6 x $10^{7}$ ) . (9.1 x $10^{-8}$ )

= (8.6 x 9.1) x $10^{7 - 8}$

= 78.26 x $10^{-1}$

= 7.8 x 10

(6.9 x $10^{5}$ ) . (4.8 x $10^{-3}$ )

= 33.12 x $10^{5 - 3}$

3.3 x $10^{3}$

(3.7 x $10^{2}$ ) . (4.6 x $10^{-3}$ ) ÷ (1.4 x $10^{-6}$ ) . (5.7 x $10^{8}$ )

= 1.7 x 10 ÷ 8 x10²

0.21 x $10^{-2}$

2.1 x $10^{-3}$

(3.1 x $10^{5}$ ) . (5.3 x $10^{-9}$ ) ÷ (7.3 x $10^{2}$ ) . (6.1 x $10^{-7}$ ) = 3.7

The television show CSI: Shoboygan has been successful for many years. That show recently had a share of 18, meaning that among

jeyben [28]

Answer:

(a) The value of P (None) is 0.062.

(b) The value of P(at least one) is 0.938.

(c) The value of P(at most one) is 0.253.

(d) The event is not unusual.

Step-by-step explanation:

Let X = number of households watching the show.

The probability of the random variable x is, P (X) = p = 0.18.

The sample selected for the survey is of size, n = 14

The random variable X follows a Binomial distribution with parameter n = 14 and p = 0.18.

The probability of a Binomial distribution is computed using the formula:

$P(X=x)={n\choose x}p^{x}(1-p)^{n-x};\ x=0,1,2,...$

(a)

Compute the probability that none of the households are tuned to CSI: Shoboygan as follows:

$P(X=0)={14\choose 0}(0.18)^{0}(1-0.18)^{14-0}=1\times1\times0.06214=0.062$

Thus, the value of P (None) is 0.062.

(b)

Compute the probability that at least one household is tuned to CSI: Shoboygan as follows:

P (X ≥ 1) = 1 - P (X < 1)

= 1 - P (X = 0)

$=1-0.062\\=0.938$

Thus, the value of P(at least one) is 0.938.

(c)

Compute the probability that at most one household is tuned to CSI: Shoboygan as follows:

P (X ≤ 1) = P (X = 0) + P (X = 1)

$={14\choose 0}(0.18)^{0}(1-0.18)^{14-0}+{14\choose 1}(0.18)^{1}(1-0.18)^{14-1}\\=0.062+0.191\\=0.253$

Thus, the value of P(at most one) is 0.253.

(d)

An event that has a very low probability of occurrence is known as an unusual event.

The probability of the event "at most one household is tuned to CSI: Shoboygan" is 0.253.

This probability value is not low.

Hence, the event is not unusual.

How are comparisons between negative numbers different than comparisons between positive numbers?

lara [203]

On a number line, numbers always increase to the right and decrease to the left. Numbers to the right are greater than numbers to the left and numbers to the left are less than numbers to the right.
