Answer: Part 1: 10,230 cookies can be expected to be within 2 two grams of the mean, 40.

Part 2: 330 cookies will be rejected for being under 36 grams.

Step-by-step explanation:

Use the percentages given in the "Normal Distribution" on the Gaussian Curve.

For Part 1 One standard deviation on either side fo the mean is 68.2%

Multiply 15000 × .682 = 10320

For part 2: 36 is 4 less than 40.

4 is two standard deviations. So look at the percentages listed outside the TwoStandard Deviations Below the Mean: 2.1% and 0.1% add to get 2.2%

Multiply 15000 × 0.022 = 330

-(7-9)z-6z=8(-6+2) solve for z

Sergeeva-Olga [200]

Answer:

(-(7-9))(z)-6z= 8(-6+2)

Simplify

-(-2)(z) -6z =8(-6+2)

Multiply 8*-6 and 8*2

2z -6z= -48+16

Combine like terms

2z+-6z =-32

-4z=-32

Divide both sides by -4

z=8

Jason decided to look at new trucks. Jason found a used truck for 34,000 dollars. A new truck is 40,000 dollars so what percent

nexus9112 [7]

Answer:

Percent of rise of a new truck on a used truck = 15%

Step-by-step explanation:

Let x be the percentage of saved money if Jason buying a used truck.

Given:

Price of the used truck = $34,000

Price of the new truck = $40,000

We need to find the percent of rise Jason saves on a used truck rather than buying a new truck

Solution:

Using a percentage formula.

$percentage\ cost = \frac{(100-x)}{100}\times Original\ cost$

Substitute Percentage cost = 34,000 and Original cost = 40,000 in above formula.

$34000 = \frac{(100-x)}{100}\times 40000$

$34000 = (100-x)\times 400$ ( $\frac{40000}{100}=400$ )

Using cross multiplication rule.

$(100-x)=\frac{34000}{400}$

$85=100-x$

$x = 100-85$

x = 15%

Therefore, Jason used 15% rise of a new truck for a used truck.
