The probability that at least 8 out of the 10 chips work properly is 0.2614, or 26.14%.
Given:
number of chips selected = 10
probability of a chip working= 0.95
The probability of getting exactly k successes in n trials with a success probability p is given by the formula:
[tex]P(X = k) =[/tex] [tex]{\text} ^nC_k p^k (1 - p)^{(n - k)[/tex]
Now, the probability
P(X ≥ 8) = P(X = 8) + P(X = 9) + P(X = 10)
[tex]P(X = k) =[/tex] [tex]{\text} ^{10}C_k (0.95)^k (1 - 0.95)^{(10 - k)[/tex]
So, P(X = 8) = [tex]^{10}C_8 (0.95)^8(1-0.95)^{10-8}[/tex]
= [tex](45) (0.95)^8 (0.05)^2[/tex]
= 0.2753
and, P(X = 9) = [tex]^{10}C_9 (0.95)^9(1-0.95)^{10-9}[/tex]
= [tex](10) * (0.95)^9 * (0.05)^1[/tex]
= 0.3874
P(X = 10) = [tex]^{10}C_{10} (0.95)^{10}(1-0.95)^{10-10}[/tex]
= [tex](1) * (0.95)^{10} * (0.05)^0[/tex]
= 0.5987
Finally, sum up these probabilities to get the desired result:
P(X ≥ 8) = P(X = 8) + P(X = 9) + P(X = 10)
= 0.2753 + 0.3874 + 0.5987
= 0.2614
Therefore, the probability is 0.2614.

1. In February 2019, 195,676 mortgages were outstanding in the UK, which represented 0.38%
of all mortgages. How many total mortgages were in the UK market at that time?
Answer:
Rounded to the nearest integer, at that time there were about 51,493,684 mortgages in the UK market.
Step-by-step explanation:
Given that in February 2019, 195,676 mortgages were outstanding in the UK, which represented 0.38% of all mortgages, to determine how many total mortgages were in the UK market at that time the following calculation must be performed:
0.38 = 195.676
100 = X
(100 x 195,676) / 0.38 = X
19,567,600 / 0.38 = X
51,493,684.21 = X
Thus, rounded to the nearest integer, at that time there were about 51,493,684 mortgages in the UK market.

Answer:
The median is 5, mode is 5, and range is 12
Step-by-step explanation:
Answer:
MEDIAN - 5
MODE - 2 (4times)
RANGE - 13-1=12 (12 is the range)
Step-by-step explanation:
MEDIAN - Arrange the data in an ascending order and the median is the middle value. If the number of values is an even number, the median will be the average of the two middle numbers.
MODE - The mode is the element that occurs most in the data set. In this case, 2 occurs 4 times.
RANGE - Subtract the minimum data value from the maximum data value to find the data range. In this case, the data range is 13-1=12
wo 6-sided number cubes are rolled for a board game. The 2 numbers are then added together to determine how many spaces the player advances on the board. Select the method of display that would be best for showing all of the outcomes for each number cube and the sums that would result. Create the display, and justify the reasoning behind your choice.
Answer:
The odds of rolling a 3 on a 6-sided number cube is 1 out of 6. The odds of rolling a 3 on either of two 6-sided cubes are 1/3. This is because 1/6 * 2 = 1/3. Therefore, an average of one-third of rolls will have a 3 in them. 1/3 expressed as a decimal is .3 repeating (.3333333 etc) and that rounds to 33 which is less than 34.

How does the distance of the mouse change every 2 seconds? 0) Every 2 seconds, the distance the mouse travels i___ by __ feet.
Time|. 0|2|4|6
Distance|0|22|44|66
There's the graph please help
Answer:
22 feet (if the distance is in feet, and the time in seconds)
Step-by-step explanation:
t = time
d = distance
To see if the mouse's distance is proportional to the time, you divide the distance with the time:
[tex]t_{3}[/tex] = 4
[tex]d_{3}[/tex] = 44
44 / 4 = 11
[tex]t_{4}[/tex] = 6
[tex]d_{4}[/tex] = 66
66 / 6 = 11 (the same as with 44 / 4. This means that the mouse distance and time is proportional)
Every second the mouse travels 11 feet.
And every other second the mouse travels 22 feet. (since (1, 11)*2 = (2, 22))
That may have been confusing, and if you have any questions, don't be afraid to ask them in the comments below!

An engineer has designed a valve that will regulate water pressure on an automobile engine. The valve was tested on 290 engines and the mean pressure was 4.1 pounds/square inch (psi). Assume the population standard deviation is 0.6. The engineer designed the valve such that it would produce a mean pressure of 4.2 psi. It is believed that the valve does not perform to the specifications. A level of significance of 0.02 will be used. Find the P-value of the test statistic. Round your answer to four decimal places.
Answer:
P-value = 0.0046
Step-by-step explanation:
Given that:
Sample size n = 290
sample mean [tex]\overline{x_1}[/tex] = 4.1
standard deviation [tex]\sigma[/tex] = 0.6
population mean [tex]\mu[/tex] = 4.2
The null and the alternative hypothesis
[tex]\mathbf{H_o: \mu = 4.2} \\ \\ \mathbf{H_a: \mu \ne 4.2}[/tex]
This is a two-tailed test.
The test statistics can be computed as:
[tex]Z = \dfrac{\overline x - \mu }{\dfrac{\sigma}{\sqrt{n}}}[/tex]
[tex]Z = \dfrac{4.1 - 4.2 }{\dfrac{0.6}{\sqrt{290}}}[/tex]
[tex]Z = \dfrac{-0.1 }{\dfrac{0.6}{\sqrt{290}}}[/tex]
Z = -2.838
P-value = P(Z> 2.838)
P-value = P(Z< -2.838) +P(Z > 2.838)
P-value = 0.00227 + (1 - 0.9977)
P-value = 0.00457
P-value = 0.0046 (to 4 decimal places)

multiplying polynomials please help me
Answer:
48p2+4p-4
Step-by-step explanation:
Answer:
48p² +4p -4
Step-by-step explanation:
A polynomial of two terms is called a 'binomial'.
Here, we are multiplying 2 binomials.
This is so common, there is a standard way to do it. The method is called FOIL, which means "firsts, outsides, insides, then lasts"
You do it like this:
multiply the 'first terms' of each binomial --> 8p*6p = 48p²
multiply the 'outside' terms, far left and far right --> 8p*2 = 16p
multiply the 'inside' terms, the two terms in the 'middle' --> -2*6p = -12p
multiply the 'last' terms of each binomial --> -2 * 2 = -4
Add 'like' terms: 48p² + (16p - 12p) -4
Answer ---> 48p² +4p -4

which inequality has the same solution set as 3(q + 6) > 11?
3q + 18 < 11
3q + 6 > 11
q + 18 > 11
q + 18 > 11
Given:
The inequality is
[tex]3(q+6)>11[/tex]
To find:
The inequality that has the same solution set as the given inequality.
Solution:
We have,
[tex]3(q+6)>11[/tex]
Using distributive property, we get
[tex]3(q)+3(6)>11[/tex]
[tex]3q+18>11[/tex]
Since the given inequality can be rewritten as [tex]3q+18>11[/tex], therefore the inequality [tex]3q+18>11[/tex] has the same solution set as [tex]3(q+6)>11[/tex].
Hence, all options are incorrect. The required inequality is [tex]3q+18>11[/tex].
Answer:
3q+18 > 11

The sum of two numbers is 20.5 and the difference of the same two numbers is 6.5.
Find the two numbers. *
Answer:
13.5 and 7
Step-by-step explanation:
x + y = 20.5
x - y = 6.5
Hence,
x = 20.5 - y
20.5 - 2y = 6.5
Hence,
2y = 14
y = 7
and x = 20.5 - y = 20.5 - 7 = 13.5
The two numbers are are 13.5 and 7.
What linear equations represents the numbers?a + b = 20.5 equation 1
a - b = 6.5 equation 2
Where a and b represents the two numbers
What is the value of b?In order to determine the value of b, subtract equation 2 from 1
2b = 14
Divide both sides by 2
b = 7
What is the value of a?Substitute for b in equation 1
a + 7 = 20.5
a = 20.5 - 7
a = 13.5
