Answer:

x = 3

Step-by-step explanation:

Given

- 3x + 2 = - 7 ( subtract 2 from both sides )

- 3x = - 9 ( divide both sides by - 3 )

x = 3

11a:
3x+5=5x-57
3x-5x=-57-5
-2x=-62
x=31
11b:
2x+2x+4x+150+4x+150=360
12x+300=360
12x=360-300
12x=60
x=5

hope this helped !!

What is the equation of the line connecting (1,5) and (4,14)?
german
To find the slope of the line:
(y2-y1)/(x2-x1)
(14-5)/(4-1)=(9)/(3)=3

Only one of your 4 possible answers has 3 as a slope. However, plugging in each point into the y=mx+b equation, the y-intercept consistently comes out as 2..
y=mx+b
14=3(4)+b  b=2
5=3(1)+b    b=2
y=3x+2
If there is a consistent, positive slope (from your question, this does not seem to have a quadratic as an option), 3x+5 is not even a viable solution because x=1 when the y-value is 5 (and thus no other x value {0} could have a y-value of 5). It seems as though you have a typo on your hands. Hopefully this helps?

A manufacturing process has a? 70% yield, meaning that? 70% of the products are acceptable and? 30% are defective. if threethree
Setler79 [48]
1. Assume the manufacturer produced 100 products.

2. 70 are acceptable and 30 are defective.

3. the first product has a probability of 70/100 to be selected from the acceptable ones. The second 69/99 (one is removed from the good ones) and the third one 68/98

4. so P(pick 3 consecutive acceptable products)=\frac{70}{100}* \frac{69}{99}* \frac{68}{98}= \frac{7*69*68}{10*99*98}==0.339

5. If familiar to the Combination formula C(n, r)=\frac{n!}{r!(n-r)!}:

P(picking 3 acceptable out of 100)=n(picking 3 acceptable)/n(picking 3)=C(70, 3)/C(100/3)=\frac{70!}{3!67!}/\frac{100!}{3!97!}=\frac{70*69*68*67!}{3!67!}/\frac{100*99*98*97!}{3!97!}= \frac{70*69*68}{3!}/\frac{100*99*98}{3!}= \frac{70*69*68}{100*99*98} = 0.339
