Answer:
2/7
Step-by-step explanation:
Since Q and R are independent, p(Q and R) will be p(Q) × p(R).
So,
p(Q) × p(R) = 4/7 × 1/2 = 4/14 = 2/7
So p(Q and R) given they are independent is 2/7

In a lab experiment, 610 bacteria are placed in a petri dish. The conditions are such that the number of bacteria is able to double every 23 hours. How long would it be, to the nearest tenth of an hour, until there are 1040 bacteria present?
Answers
Answer:
It would take 19 hours and 36 minutes until there are 1040 bacteria present.
Step-by-step explanation:
Given that in a lab experiment, 610 bacteria are placed in a petri dish, and the conditions are such that the number of bacteria is able to double every 23 hours, to determine how long would it be, to the nearest tenth of an hour, until there are 1040 bacteria present, the following calculation must be performed:
610X = 1040
X = 1040/610
X = 1.7049
2 = 23
1.7049 = X
1.7049 x 23/2 = X
39.2131 / 2 = X
19.6 = X
100 = 60
60 = X
60 x 60/100 = X
36 = X
Therefore, it would take 19 hours and 36 minutes until there are 1040 bacteria present.

A. g(x) = |x + 5|
B. g(x) = |x| + 5
C. g(x) = |x| - 5
D. g(x) = |x - 5|
Answers
Answer:
B. g(x)= |x| + 5
Step-by-step explanation:
-5 represents a vertical shift down, so that narrows it down to either A or B. A shows a shift across the horizontal (X) axis, so it must be B.
oduced the test statistic χ2=8.95 with a corresponding p-value of 0.03. Which of the following is correct?

Answer A: There is sufficient evidence to reject the null hypothesis at the 0.05 level since the test statistic is greater than the p -value. A
Answers
Answer:
The null hypothesis must be rejected
Step-by-step explanation:
Here the P value is less than 0.05
which means that the test results are statistically significant and there are sufficient evidence to reject the null hypothesis and accept the alternative hypothesis.
Hence, the null hypothesis must be rejected.

log(x)²=(logx)², find the value of x
Answers
Answer:
x = 7.39
Step-by-step explanation:
log(x)²=(logx)², find the value of x
log x² = log x * log x
2log x = log x * log x
2 = log x
Take the exponent pf both sides
e² = e^logx
e² = x
x = e²
x = 7.39

Answers

Answer:
B. 2 +3x
Step-by-step explanation:
The greatest common factor of 12 and 18 is 6:
12 = 6×2
18 = 6×3
The greatest common factor of x² and x is x². Factoring out the greatest common factors, we have ...
12x² +18x³ = 6x²(2 +3x)
The factors are 6x² or (2 +3x). The last of these is an answer choice.
2 +3x is a factor

A researcher is going to estimate the average typing speed of students of a college. He selects a random sample of 20 students and finds the average typing speed of 70 wpm and the standard deviation of 5 wpm. Estimate the lower bound of the 80% confidence interval of the average typing speed of a student of this college. Express your answer using THREE decimal places
Answers
Answer:
The lower bound of the 80% confidence interval of the average typing speed of a student of this college is of 68.516 words per minute.
Step-by-step explanation:
We have the standard deviation for the sample, which means that the t-interval is used to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 20 - 1 = 19
80% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 19 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.8}{2} = 0.9[/tex]. So we have T = 1.328
The margin of error is:
[tex]M = T\frac{s}{\sqrt{n}} = 1.328\frac{5}{\sqrt{20}} = 1.484[/tex]
In which s is the standard deviation of the sample and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 70 - 1.484 = 68.516 wpm.
The lower bound of the 80% confidence interval of the average typing speed of a student of this college is of 68.516 words per minute.

The function P(x) for the profit the company earns per year is P(x) = 4x^2 - 8x + 125
How to calculate the profit functionFrom the given information, we have the following
revenue function f(x) = 4x^2 + 2x
Cost per year C(x) = 10x+ 125
The profit = Revenue - Cost
P(x) = 4x^2 + 2x - 10x+ 125
P(x) = 4x^2 - 8x + 125
Hence function P(x) for the profit the company earns per year is P(x) = 4x^2 - 8x + 125

2. x = 1, y = 2, z = -1, w = -2
Step-by-step explanation:
1. Matrices are added term by corresponding term. Consider the upper left term in each matrix. The equation says 4 + 3 = 8. This is nonsense, so we cannot figure what you expect to solve.
__
2. This resolves to 4 equations:
3y = 6 ⇒ y = 23z = -3 ⇒ z = -12y+4x = 8 ⇒ 4+4x = 8 ⇒ x = 12z = w ⇒ -2 = wThe solutions are ...
(w, x, y, z) = (-2, 1, 2, -1)
