Mathematics

Brilliant_brown [7]3 years ago

Answer:

-2x + 2 - h

as h approaches 0 this approaches -2x + 2.

Step-by-step explanation:

Difference quotient:

=  -(x + h)^2 + 2(x + h)  - (-x^2 + 2x) / h

= - (x^2 + 2hx + h^2) + 2x + 2h + x^2 - 2x / h

= -x^2 - 2hx - h^2 + 2x + 2h + x^2 - 2x / h

=  (-2hx + 2h - h^2) / h

= -2x + 2 - h

As h approaches zero this approaches -2x + 2 which is the derivative of the function.

Answer:

Store C has the lowest price of $7.00

Step-by-step explanation:

Store A's sale gets you 15% off the shoes. 15% of 35 is $25.50

Store B's sale gets you $5.00 off the shoes. $35.00 - $5.00 = $30.00

Store C's sale gets you 1/5 off the shoes. 1/5 of $35.00 is $7.00

That means that the only true statement is the Store C's shoes are $7.00

Hope this helps you for next time you get a problem like this.

Samples of rejuvenated mitochondria are mutated (defective) in 1% of cases. Suppose 18 samples are studied, and they can be cons
Temka [501]

Probability that no samples are mutated is 0.83, probability that at most one sample is mutated is 0.9812 and probability that more than half the samples are mutated is 0.

Given percentage of rejuvenated mitochondria defective is 1%, and sample size is 18.

Binomial distribution is the probability of exactly x successes on n repeated trials and X can have two outcomes.

P(X=x)=C_{n,x} p^{x}(1-p)^{n-x}

percentage of defective rejuvendated mitochondria=1%

p=0.01

Sample size=18

n=18

a) No samples are mutated

This means P(X=0)=C_{18,0}(0.01)^{0} (0.99)^{18}

=0.83

b) At most one sample is mutated.

P(X<=1)=P(X=0)+P(X=1)

so,

P(X=0)=C_{18,0} (0.01)^{0}  (0.99)^{18}

=0.83

P(X=1)=C_{18,1}(0.01)^{1} (0.99)^{17}=

=0.1512

P(X<=1)=0.83+0.1512

=0.9812

c) More than half the samples are mutated.

P(X>9)=P(X=10)+P(X=11)+P(X=12)+P(X=13)+P(X=14)+P(X=15)+P(X=16)+P(X=17)+P(X=18)

Using two decimals digits precision all will be 0.

Hence Probability that no samples are mutated is 0.83, probability that at most one sample is mutated is 0.9812 and probability that more than half the samples are mutated is 0.
