Answer:

144

Step-by-step explanation:

Think of PEMDAS(Please(Parenthesis),Excuse(Exponents),My Dear(Multiplication and Division), Aunt Sally(addition and subtraction).

Since this has Parenthesis you would have find out what was in the Parenthesis first(Please).

5+7=12

Now you look for exponents. The exponent is 2 and that means multiply the 12 by itself (12(12).

Giving you 144.

Answer:

see below

Step-by-step explanation:

x⁵ - 8x⁴ + 22x³ - 26x² + 21x - 18 = 0

x = 2, x = ± i, x=3 with multiplicity 2

-----------------------------------------------------

x⁴ - 5x³ + 7x² - 5x + 6 = 0

x = 2, x=3, x = ± i

--------------------------------------------------------

-1 + 4i = 4 + i

--------------------------------------------------------

x³ - 26x² + 21x - 18 = 0

x = ± 2i, x = 3/2

--------------------------------------------------------

(1 + i) (-3 - 4i)

= 1 - 7i

--------------------------------------------------------

(-5 + 2i) + (3 - 6i)

= -2 -4i

--------------------------------------------------------

x⁴ + 5x² + 4 = 0

x = ± i , x = ± 2i

--------------------------------------------------------

(7 - i) - (-5 + 6i)

= 12 - 7i

--------------------------------------------------------

(4 - i) (4 + i)

= 17

--------------------------------------------------------

10.

(3 + 8i) (4 - 3i)

= 36 + 23i

A survey of 37 students at the Wall College of Business showed the following majors: Accounting 9 Finance 6 Economics 3 Manageme

Dmitry [639]

Answer:

10/37.

Step-by-step explanation:

The probability that he or she is a management major is 10/37.

The concept of probability that was used was:

Classical probability: The probability is equal to (number of favourable cases) / (number of total cases). Since the total of students who are a management major is 10 and we have 37 students in total, the probability will be 10/37.

Use a statistics calculator to find the area, in decimal form, rounded to four places after the decimal, under the (standard) No

Jlenok [28]

Answer:

a) 0.9641.

b) 0.0082

c) 0.0277

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

(a) ...to the left of 1.8.

p-value of Z = 1.8, which, looking at the z-table, is of 0.9641.

(b) ...to the right of 2.4.

1 subtracted by the p-value of Z = 2.4.

Looking at the z-table, Z = 2.4 has a p-value of 0.9918.

1 - 0.9918 = 0.0082, which is the answer.

(c) ...between 1.8 and 2.4.

p-value of Z = 2.4 subtracted by the p-value of Z = 1.8.

From itens a and b, we have both. So

0.9918 - 0.9641 = 0.0277

What's greater then 3/8 or 2/4

iVinArrow [24]

Convert 2/4 to 4/8 and then look at the numerators. since 4 is greater than 3, 2/4 is greater than 3/8
