Answer:

$\frac{ {7x}^{2} - 5x + 1}{4x + 1}$

Step-by-step explanation:

Since the denominators are the same we just have to combine the top.

${x}^{2} - 5x + {6x}^{2} + 1$

Combine alike terms.

${7x}^{2} - 5x + 1$

put that over our denominator.

$\frac{ {7x}^{2} - 5x + 1 }{4x + 1}$

sp2606 [1]

Answer: 0.0004951

Step-by-step explanation:

Given

Five cards are from the deck

The total number of cards in the deck is 52

total spades card is $13$

We have to choose 5 cards out of 13, this can be done in

$\Rightarrow ^{13}C_5$

The probability of choosing 5 spade cards is

$\Rightarrow P=\dfrac{^{13}C_5}{^{52}C_5}\\\\\Rightarrow P=\dfrac{1287}{2598960}=0.0004951$

A class has average height of 68 inches and a standard division of 2 inches what height do you need to be taller than 90% of the

Y_Kistochka [10]

Answer:

65.426

Step-by-step explanation:

Given that:

Mean height (m) = 68 inches

Standard deviation (s) = 2 inches

Height required to be taller than 90% of the class :

P(Z > x) = 0.9

The corresponding Zscore is - 1.282 (Z probability calculator)

Using the Zscore relation :

Zscore = (x - m) / s

-1.282 = (x - 68) / 2

-1.282 * 2 = x - 68

-2.564 = x - 68

-2.564 + 68 = x

x = 65.436
