Which of the value of x satisfies the equation below -2x-7=12

Masteriza [31]

Answer is A.
You start by adding the 7 to the opposite side. Giving you 19. You divide both sides by -2 which gives you x on one side and -9.5 on the other.

-2x-7=12
-2x=12(+7)
-2x=19
x=19/-2
x=-9.5

Sam found that 25% of the 236 patients he saw in a week were near-sighted. How many of the patients Sam saw were near-sighted?Sa

iris [78.8K]

Answer:

59 patients

Step-by-step explanation:

Total patients Sam saw in a week = 236

Percentage of patients near-sighted = 25%

How many of the patients Sam saw were near-sighted?

Number of patients near-sighted = 25% of 236

= 25/100 × 236

= 0.25 × 236

= 59

Number of patients near-sighted = 59 patients

The number of patients Sam saw in a week that were near-sighted is 59 patients

A cookie factory monitored the number of broken cookies per pack yesterday.

trapecia [35]

Answer:

Confidence Interval - 2.290 < S < 2.965

Step-by-step explanation:

Complete question

A chocolate chip cookie manufacturing company recorded the number of chocolate chips in a sample of 50 cookies. The mean is 23.33 and the standard deviation is 2.6. Construct a 80% confidence interval estimate of the standard deviation of the numbers of chocolate chips in all such cookies.

Solution

Given

n=50

x=23.33

s=2.6

Alpha = 1-0.80 = 0.20

X^2(a/2,n-1) = X^2(0.10, 49) = 63.17

sqrt(63.17) = 7.948

X^2(1 - a/2,n-1) = X^2(0.90, 49) = 37.69

sqrt(37.69) = 6.139

s*sqrt(n-1) = 18.2

$s\sqrt{\frac{n-1}{X^2 _{(n-1), \frac{\alpha }{2} } }$ $\leq \sigma \leq s\sqrt{\frac{n-1}{X^2 _{(n-1), 1-\frac{\alpha }{2} } }$

confidence interval:

(18.2/7.948) < S < (18.2/6.139)

2.290 < S < 2.965
