Answer:
m=-4
Step-by-step explanation:
The formula that you're using is called slope intercept form, (y=mx+b). m equals the slope so the slope would be -4.

sophia scored 92 percent in a math test. If the test had 50 questions, how many did she get right?
Answer:
Sophia got 46 questions right.
Step-by-step explanation:
Heres why:
In order to find how much she got right, we put 92% over 100 and make it a fraction so that would be 92/100.
Now, she had 50 questions. So, we will put that over 1. So that would look like this: 50/1.
Finally, we multiply: 92/100 times 50/1.
This equals 4600/100 which equals 46
SO: Sophia got 46 questions right! Hope this helps and plz mark brainliest if you want to! :)
A poll asked 1057 American adults if they believe there was a conspiracy in the assassination of President Kennedy, and found that 614 believe there was a conspiracy. Estimate the proportion of Americans who believe in this conspiracy using a 95% confidence interval. Round to three decimal places.
Answer:
The 95% confidence interval of the proportion of Americans who believe in the conspiracy is [tex] 0.551< p < 0.610[/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n =1057
The number that believe there was a conspiracy is k = 614
Generally the sample proportion is mathematically represented as
[tex]\^ p = \frac{614}{1057 }[/tex]
=> [tex]\^ p = 0.5809[/tex]
From the question we are told the confidence level is 95% , hence the level of significance is
[tex]\alpha = (100 - 95 ) \%[/tex]
=> [tex]\alpha = 0.05[/tex]
Generally from the normal distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] is
[tex]Z_{\frac{\alpha }{2} } = 1.96[/tex]
Generally the margin of error is mathematically represented as
[tex]E = Z_{\frac{\alpha }{2} } * \sqrt{\frac{\^ p (1- \^ p)}{n} } [/tex]
=> [tex]E = 1.96 * \sqrt{\frac{0.5809 (1- 0.5809)}{1057} } [/tex]
=> [tex]E = 0.02975 [/tex]
Generally 95% confidence interval is mathematically represented as
[tex]\^ p -E < p < \^ p +E[/tex]
=> [tex] 0.5809 - 0.02975< p < 0.5809 + 0.02975[/tex]
=> [tex] 0.551< p < 0.610[/tex]
Nathan had an infection, and his doctor wanted him to take penicillin. Because Nathan’s father and paternal grandfather were allergic to penicillin, Nathan has a 75% chance of having the same allergy. The doctor performed a skin test to see whether Nathan would react to it. The test is 98% accurate. If the test predicts that Nathan is not allergic to penicillin, what is the probability after the test that Nathan is not allergic to the drug?
A.
0.1135
B.
0.2450
C.
0.9423
D.
0.9932
Answer:
im late but if anyone sees this question its 0.9423
Step-by-step explanation:
The test predicting that he does not have the drug and is correct is 0.98 x 0.25.
Predicting that he does not have the drug but is wrong is 0.02 x 0.75
[tex]\frac{ (0.98 * 0.25)}{ (0.98 * 0.25) + (0.02 * 0.75} \\\\=\frac{ (0.245)}{ (0.245) + (0.015)} \\\\= \frac{ 0.245}{ 0.26} \\\\=0.9423[/tex]

2/3 divided by 4 in simplest form
Answer:
it's 1//6
Step-by-step explanation:
I used the calculator, and its 1/6
Note: Make Me BRAINLIEST PLZZ..
Answer:
0.16 or 1/6
Explanation:
2/3 divided by 4 is 0.16666666666
0.16666... = 0.1 + 0.06666...
x = 0.06666... / · 10
10 x = 0.66666...
10 x = 0.6 + 0.6666...
10 x = 0.6 + x
9 x = 0.6
x = 0.6/9 = 6/90 = 1/15
0.166666... = 0.1 + 1/15 = 1/10 + 1/15 = (2 + 3) / 30 = 5/30 = 1/6
Help plz i have only tonight 11;59
Answer:
Base = 16, height 64
Step-by-step explanation:
It's a triangle so u have to multiply it with 1/2 or divide by 2, x will equal both height and base:
(1/2)4x^2 = 512
Multiply 2 to both sides
4x^2 = 1024
divide both sides by 4
x^2 = 256
[tex]\sqrt{x^2}[/tex] = [tex]\sqrt{256}[/tex]
x = 16, base is 16 and height is 16(4) = 64
Alright this took me some time but I got it now, u might think why 16 and 64? 16 times 64 is not 512, but the equation for a triangles area is [tex]\frac{b h}{2}[/tex] or b·h·1/2 , so if u plug the numbers into the equation it will equal 512:
16 · 64 · 1/2= 1024 · 1/2 = 512

Which shows the expressions in the order they would appear on a number line from least to greatest? (5 points)
A. 2 to the power of 3, square root of 5, square root of 20, square root of 11, 11 over 9
B. 2 to the power of 3, square root of 11, 11 over 9, square root of 20, square root of 11
C. 11 over 9, square root of 5, square root of 11, square root of 20, 2 to the power of 3
D. 11 over 9, 2 to the power of 3, square root of 5, square root of 20, square root of 11
Answer:
C) 11/9, [tex]\sqrt{5}[/tex] , [tex]\sqrt{11}[/tex], [tex]\sqrt{20}[/tex], 2^3
Step-by-step explanation:
2^3 = 8
[tex]\sqrt{5}[/tex] = 2.236....
[tex]\sqrt{20}[/tex] = 4.472...
[tex]\sqrt{11}[/tex] = 3.317...
11/9 = 1.222...
So from least to greatest:
11/9, [tex]\sqrt{5}[/tex] , [tex]\sqrt{11}[/tex], [tex]\sqrt{20}[/tex], 2^3
The answer would be C.
Suppose a box contains 3 defective light bulbs and 12 good bulbs. Two bulbs are chosen separately from the box without replacement. What is the probability that one of two bulbs drawn is defective and one is not?
Answer:
[tex]Probability = \frac{12}{35}[/tex]
Step-by-step explanation:
Given
Represent Defective Bulbs with D and non good bulbs with G
[tex]D = 3[/tex]
[tex]G = 12[/tex]
The probability that one is defective and the other is not can be represented with: (D and G) or (G and D)
Which means that the defective is selected first, then the good one or the good one is selected first, then the defective one.
This is then calculated as:
[tex]Probability = \frac{n(D}{Total} * \frac{n(G)}{Total - 1} + \frac{n(G}{Total} * \frac{n(D)}{Total - 1}[/tex]
We used Total - 1 on second selections because it is a probability without replacement
[tex]Probability = \frac{3}{15} * \frac{12}{15- 1} + \frac{12}{15} * \frac{3}{15- 1}[/tex]
[tex]Probability = \frac{3}{15} * \frac{12}{14} + \frac{12}{15} * \frac{3}{14}[/tex]
[tex]Probability = \frac{1}{5} * \frac{6}{7} + \frac{2}{5} * \frac{3}{7}[/tex]
[tex]Probability = \frac{6}{35} + \frac{6}{35}[/tex]
[tex]Probability = \frac{12}{35}[/tex]
