Mathematics

Natasha2012 [34]3 years ago
6 0

x = ½

x = 0.5

Step-by-step explanation:

6x + 9 = 12

Collect like terms and simplify

6x = 12 - 9 \\ 6x = 3

Divide both sides of the equation by 6

\frac{6x}{6}  =  \frac{3}{6}  \\  \\ x =  \frac{1}{2}

Write a problem to fit this equation 2K + 5 =29
Degger [83]

2K + 5 = 29

(2 x K) + 5 = 29

29 - 5 = 24

24 divided by 2 = 12 (This is K)

K = 12

(2 x 12) + 5 = 29  


24 + 5 = 29

<h3>Answer:</h3>

3)  likely

4)  1/2; equally likely

<h3>Step-by-step explanation:</h3>

3) You are being asked to translate a numerical value to a subjective statement. There are no hard-and-fast rules for this. Generally, the meanings of the terms you're asked to choose from are ...

  • impossible: probability is zero. The outcome cannot occur.
  • unlikely: chances are less than even; often, "unlikely" means a probability of 10%, 5%, 1% or lower, depending on the context.
  • equally likely: probability is near 50%
  • likely: more likely than not. Again, this depends on the context.
  • certain: probability is 1. There is no chance the outcome will not occur.

An 80% probability is greater than 50%, so might reasonably be called "likely."

___

4) a. Four of the eight numbers are even, so the probability of obtaining an even number at random is 4/8 = 1/2.

  b. A probability of 50% might reasonably be called "equally likely", as the probability the event will occur is equal to the probability it won't.

nata0808 [166]

Answer: $1296

Step-by-step explanation:

Surface area of s sphere = 4πx r^2

Diameter = 1/2 radius

Surface area = 4π x 12^2

= 1809.56 cm^2 = 18.096 m^2

Material required = 71.62 x 18.096

= $1296
