slega [8]

Answer:

a) After adding the 0 test score, the mean would be the most appropriate measure of center to describe the data-------> is true

b) After adding the 0 test score, the mean would be affected-----> is true

c) After adding the 0 test score, the median would be the most appropriate measure of center to describe the data-----> is false

d) Before the missed test, Eva’s median score was 96-----> is false

e) Before the missed test, Eva’s median score was 91------ is true

The probability that a lab specimen contains high levels of contamination is 0.10. A group of 4 independent samples are checked.

galben [10]

Answer:

a) 0.6561

b) 0.2916

c) 0.3439

Step-by-step explanation:

We are given the following information:

Let us treat high level of contamination as our success.

p = P(High level of contamination) = P(success) = 0.10

n = 4

The, by binomial distribution:

$P(X=x) = \binom{n}{x}.p^x.(1-p)^{n-x}\\\text{where x is the number of success}$

a) P(No high level of contamination)

We put x = 0, in the formula.

$P(X=0) = \binom{4}{0}.(0.10)^0.(1-0.10)^{4} =0.6561$

Probability that no lab specimen contain high level of contamination is 0.6561

b) P(Exactly one high level of contamination)

We put x = 1, in the formula.

$P(X=1) = \binom{4}{1}.(0.10)^1.(1-0.10)^{3} =0.2916$

Probability that no lab specimen contain high level of contamination is 0.6561

c) P(At least one contains high level of contamination)

$p(x \geq 1) = 1 - p( x = 0) = 1 - 0.6561 = 0.3439$

Probability that at least 1 lab specimen contain high level of contamination is 0.3439

Estimate the limit<br><br> A <br> B <br> C<br> D

Lera25 [3.4K]

Answer:

C. $\lim_{x\rightarrow f(x)=2$

Step-by-step explanation:

Given problem is $\lim_{x\rightarrow \frac{\pi}{4}}\frac{tan(x)-1}{x-\frac{\pi}{4}}$ .

Now we need to evaluate the given limit.

If we plug $\x=\frac{\pi}{4}$ , into given problem then we will get 0/0 form which is an indeterminate form so we can apply L Hospitals rule

take derivative of numerator and denominator

$\lim_{x\rightarrow \frac{\pi}{4}}\frac{tan(x)-1}{x-\frac{\pi}{4}}$

$=\lim_{x\rightarrow \frac{\pi}{4}}\frac{sec^2(x)-0}{1-0}$

$=\frac{sec^2(\frac{\pi}{4})-0}{1-0}$

$=\frac{(\sqrt{2})^2}{1}$

$=\frac{2}{1}$

=2

Hence choice C is correct.

The base of a parallelogram is 10 units and the height is 7units. A segment divides the parallelogram into two identical trapezo

sveticcg [70]

If you need area of the trapezoids:

Area of parallelogram = 10×7 = 70 sq. units

Area of each trapezoid = 1/2 × area of parallelogram = 1/2 × 70 = 35 sq. units

Answer:

5x^4+7x^3-6x^2

Step-by-step explanation:

$(x^{2} +2x)(5x^{2} -3x)\\\= 5x^{4}-3x^{3} +10x^{3} -6x^{2}\\= 5x^{4}+7x^{3} -6x^{2}$
