What is the solution of the proportions 22/11 = r/13?
vagabundo [1.1K]
R=26, you can use cross multiplication to figure this proportion out. 22 times 13 is 286 and 11 times r is 11r , leaving you with 286=11r. you would then divide each side by 11 to isolating the variable giving you r=26.

elena-14-01-66 [18.8K]

Complete Question

The quality control manager at a computer manufacturing company believes that the mean life of a computer is 91 months with a standard deviation of 10 months if he is correct. what is the probability that the mean of a sample of 68 computers would differ from the population mean by less than 2.08 months? Round your answer to four decimal places. Answer How to enter your answer Tables Keypad

Answer:

P(-1.72

Step-by-step explanation:

From the question we are told that:

Population mean \mu=91

Sample Mean \=x =2.08

Standard Deviation \sigma=10

Sample size n=68

Generally the Probability that The  sample mean  would differ from the population mean

P(|\=x-\mu|<2.08)

From Table

P(|\=x-\mu|

T Test

Z=\frac{\=x-\mu}{\frac{\sigma}{\sqrt{n} } }

Z=\frac{2.08}{\frac{10}{\sqrt{68} } }

Z=1.72

P(|\=x-\mu|

P(-1.72

Therefore From Table

P(-1.72

Solve by factoring: 2x2 - 5x - 12 = 0
Zepler [3.9K]

Step-by-step explanation:

2 {x}^{2}  - 5x - 12

2 {x}^{2}   - 8x  + 3x - 12

2x(x - 4) + 3(x - 4)

2x  + 3 = 0 \:  \: x - 4 = 0

x =  \frac{ - 3}{2}  \:  \: x =4
