Answer:
See below for all information
Step-by-step explanation:
Given Information
Observed Sample Proportion: [tex]p=\frac{33}{362}\approx0.0912[/tex]Hypothesized Population Proportion: [tex]p_0=0.10[/tex]Sample Size: [tex]n=362[/tex]Significance Level: [tex]\alpha=0.05[/tex]We should conduct a two-tailed one-proportion z-test (remember to double the p-value to consider both tails!)Assume conditions are metNull and Alternate Hypotheses
Null: [tex]H_0:p=0.10[/tex] (this tells us that the actual proportion of inaccurate orders of 10% is equal to the observed proportion of inaccurate orders)Alternate: [tex]H_1:p\neq0.10[/tex] (this tells us that the actual proportion of inaccurate orders of 10% is NOT equal to the observed proportion of inaccurate orders)Determine z-statistic
[tex]\displaystyle Z=\frac{p-p_0}{\sqrt{\frac{p_0(1-p_0)}{n}}}=\frac{\frac{33}{362}-0.10 }{\sqrt{\frac{0.10(1-0.10)}{362}}}\approx-0.5606[/tex]
Determine p-value from z-statistic
[tex]2\cdot P(Z < -0.5606)=2\cdot\text{normalcdf}(-1E99,-0.5606)\approx2\cdot0.28753\approx0.5751[/tex]
Draw conclusion of p-value based on given significance level
Since [tex]p > 0.05[/tex], we fail to reject the null hypothesis. This means that we do have sufficient evidence to say that the observed rate of inaccurate orders is equal to 10%, making it extremely likely that the null hypothesis is true.

what is the approximate value of x in the exponential 4^x=14?
Answers
We know 4² = 16 , 4¹= 4
In this case we have :-
[tex] {4}^{x} = 14[/tex]
and we have to find the value of x
14 is less than 16 so x will be less than 2
14 is greater than 4 so x will be greater than 1
we can find the value of
[tex] {4}^{1.5} = {4}^{ \frac{3}{2} } \\ { (\sqrt{4}) }^{3} = {2}^{3} = 8[/tex]
so we can say 14 is much larger than 8 which means x will be much larger than 1.5
so according to above ideas we can say our answer is 2nd option which is 1.9037 is our answer
[tex]x \approx1.9037[/tex]
[tex]~~~~~~~4^x = 14 \\\\\implies \ln 4^x = \ln 14\\\\\implies x \ln 4 = \ln 14\\ \\\implies x = \dfrac{\ln 14}{ \ln 4}\\\\\implies x \approx 1.9037[/tex]
Niki wants to buy all the fruits as shown on the menu. If she gets a discount of $50 off the cost of the Cherry and $25 each off the remaining fruits, how much will Niki pay after the discounts?
fruit menu
fruits. Quality. cost
1.cherry 11b. $150
2.bananas ¼ doz. $200
3.watermelon. 11b. $125
mangos. each. $ 75
Answers
Answer:
Niki will pay $425 after the discounts.
Step-by-step explanation:
Cherry originally costs 150$, and you can subtract the discount of 50$ from that to get 100$ total for cherries.
Banana originally costs 200$, and you can subtract the discount of 25$ from the original cost to get 175$ total for bananas.
Watermelon originally costs 125$, and after subtracting the discount of 25$, you can determine the total cost for watermelons, which is 100$.
Mangoes originally costs 75$, subtract the discount of 25$, and you get the total for mangoes at 50$.
Add the costs after discounts (100$ for cherry, 175$ for banana, 100$ for watermelon, 50$ for mangoes), and you get 425$, which is the total cost for the fruit after discounts.

Determine the equation of the line passing through the points (−1,1) and (1,7).
Write the line in standard form Ax+By=C.
Answers
Answer:
[tex]3x - y = -4[/tex]
Step-by-step explanation:
To make things easier, let's first find the equation in slope-intercept form ([tex]y = mx + b[/tex] where m is the slope and b is the y-intercept.
1. Find the slope:
[tex]\frac{7 - 1}{1 - (-1)} = \frac{6}{2} = 3[/tex]
2. Find the y-intercept by plugging in (-1,1) into the equation [tex]y = 3x + b[/tex]
[tex]1 = 3(-1) + b[/tex]
so [tex]b[/tex] = 4
3. Therefore the equation of the line in slope-intercept form is [tex]y = 3x + 4[/tex]
4. To convert slope-intercept form into standard form, let's move the 3x over to the other side and divide by -1 to get rid of the negative.
Our result is [tex]3x - y = -4[/tex].

What is the 16th term in the following geometric sequence?
5, −10, 20, −40, 80,...
Answers
Explanation:
The formula to find the nth term for a geometric sequence is
(a1)(r)^n-1
So by plugging in the terms you get
(5)(-2)^16-1 = -163840
Step-by-Step Explanation:
As we can see, starting from the first term, every term is repeatedly multiplied by (-2) in order to form this sequence.
1) 5
2) 5 * -2 = -10
3) -10 * -2 = 20
4) 20 * -2 = -40
5) -40 * -2 = 80
6) 80 * -2 = -160
7) -160 * -2 = 320
8) 320 * -2 = -640
9) -640 * -2 = 1280
10) 1280 * -2 = -2560
11) -2560 * -2 = 5120
12) 5120 * -2 = -10240
13) -10240 * -2 = 20480
14) 20480 * -2 = -40960
15) -40960 * -2 = 81920
16) 81920 * -2 = -163840
17) -163840 * -2 =327680
Therefore, 16th Term = -163840

Find the Mean Absolute Deviation (MAD) of the following test scores.
Remember, the Mean is just the first step.
Scores:
{ 48, 61, 73, 76, 76, 74 }
Answers
Based on the calculation below, the Mean Absolute Deviation (MAD) of the test scores is 0.
How to calculate Mean Absolute Deviation (MAD)The mean of the 6 test scores is first calculated as follows:
Mean = Sum of the test scores / Number of test scores = (48 + 61 + 73 + 76 + 76 + 74) / 6 = 68
We can now calculate the MAD of the test scores as follows:
MAD = Sum of deviations of all the test scores from the Mean / Number of test scores = ((48 - 68) + (61 – 68) + (73 – 68) + (76 – 68) + (76 – 68) + (74 – 68)) / 6 = 0 / 6 = 0
