Sergeu [11.5K]3 years ago
8 0

Step-by-step explanation:

10 - <em>3x</em><em> </em><em>=</em> x-4

Collect like terms

10 +4 = x + 3x

14 = 4x

Divide both sides by 4

<em>X</em><em> </em><em>=</em><em> </em><u>14</u>

4

= <u>7</u>

There is a bag filled with 2 blue, 4 red and 3 green marbles.
Lyrx [107]

Answer:

.753

Step-by-step explanation:

Let Ps = probability both marbles are the same color.

Let Pd = probability both marbles are a different color.

Pd = 1 -Ps

Let Pb = probability both marbles are blue

Let Pr = probability both marbles are red.

Let Pg = probability both marbles are green

Pb= 2/9 * 1/9 = 2/81

Pr= 4/9 * 3/9 = 12/81

Pg=.3/9 * 2/9= 6/81

Ps = Pb + Pr +Pg= 20/81

Pd =1-Ps= 61/81 = .753

Is this correct?

The mean weight of the domesticated house cat is 9.2 pounds with a standard deviation of 3.4 pounds. If a cat has a z-score of -
ra1l [238]

Answer:

4.78 pounds

Step-by-step explanation:

We solve the above question using z score formula

z = (x-μ)/σ, where

x is the raw score

μ is the population mean = 9.2 pound

σ is the population standard deviation = 3.4 pounds

z = 1.3

We are to find x

Hence,

-1.3 = x - 9.2/3.4

Cross Multiply

-1.3 × 3.4 = x - 9.2

-4.42 = x - 9.2

x = -4.42 + 9.2

x = 4.78 pounds.

Therefore the weight of the cat is 4.78 pounds

divide both numbers by the GCF and the final simplest ratio is 5:1
