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. What is the probability that Nathan is not allergic to penicillin and the test predicts it?

Describe how you know that (8+9)+3 is equivalent to 8+(9+3). What is the benefit to using this property
Answer:
Associative property of addition
Step-by-step explanation:
The associative property of addition is as follows :
a+(b+c) = (a+b)+c
We have,
a = 8, b = 9 and c = 3
So,
Using above property,
(8+9)+3 = 8+(9+3)
20 = 20
Hence, this is the required solution.

solve for x
2 + x^2 = 18
Answer:
16
Step-by-step explanation:
Answer:
4 and -4
Step-by-step explanation:
To solve, just isolate x
2+x^2=18
subtract both sides of the equation by 2
x^2=16
find the square root of 16
(remember, no matter if a number is positive or negative, if it is squared, it automatically becomes positive)
to get:
x=4
and
x= -4

Use the information from the graphs to write the equation in y=ab*^x
Answer:
1). y = 4(1.75)ˣ
2). y = (2)ˣ
Step-by-step explanation:
1). Let the equation of the given exponential graph is,
y = a(b)ˣ
Graph of the given equation passes through two points (0, 4) and (0+1, 4+3)
For point (0, 4),
4 = a(b)⁰
a = 4
For point (1, 7),
7 = 4(b)¹
b = [tex]\frac{7}{4}[/tex]
b = 1.75
Therefore, equation of the function is,
y = 4(1.75)ˣ
2). Similarly, equation of the second graph will be same in the form of
y = a(b)ˣ
Second graph passes through the points (0, 1) and (2, 4)
For (0, 1),
1 = a(b)⁰
a = 1
For (2, 4),
4 = 1(b)²
b = 2
Therefore, exponential function representing the graph will be,
y = 1(2)ˣ
y = 2ˣ

Which choice is similar to the figure shown?
Please help I’m confused on what to do.
The top left figure is similar with the figure given in this problem.
What are similar figures?Two figures are defined as similar triangles when they share these two features listed as follows:
Congruent angle measures, as both triangles have the same angle measures.Proportional side lengths, which helps us find the missing side lengths.Hence the top left figure is similar with the figure given in this problem, as:
5/2 = 20/8.The angle measures are the same.More can be learned about similar figures at brainly.com/question/14285697

Matt decides the length of his table will be 15 in. He calculates that the area of the table is 30 in. squared. Determine if Matt’s calculation is correct
Answer:No Matt's calculation is not correct.
Step-by-step explanation:
We have to multiply by the number of the area.If it is 4 inches we multiply by 4
15 x 4 =60
A=4 inches squared
A=LxW (length x width )
so you can say that:
Matt is incorrect because He skipped the step of multiplying 2 by 2 in the formula which is where we get 4 from.

Write this word sentence as an equation. 82 is the difference of a number b and 24
Answer:
106 - 24 = 82
Step-by-step explanation:
b = 106, solve 106 - 24 and you get 82.
Hope this helped.
Answer:
b/24=82
Step-by-step explanation:
Since the difference of an equation is the outcome of division we place 82 as the answer.
Also, since 82 is greater than 24 we can assume that the variable "b" is larger than both 82 and 24.
b. 21.8°

Can I Get Help Pls Damon drew a scale drawing of a swimming pool. The scale he used was 1 inch : 9 feet. The diving board is 2 inches long in the drawing. How long is the actual diving board?
Answer: 18 ft
Step-by-step explanation:
Given
Scale is 1inch:9 feet
1 feet= 12 inch
The dividing board is 2 inches long
Suppose the actual length of the diving board is x
[tex]\therefore \dfrac{1}{9\times 12}=\dfrac{2}{x}\\\\\Rightarrow x=\dfrac{9\times 12\times 2}{1}\\\\\Rightarrow x=216\ inch\ \text{or}\ 18\ ft[/tex]

Answer:
[tex]slope = 1 [/tex]
Step-by-step explanation:
We can see that the graph cuts the x axis at , (-1,0) and y axis at (0,1) . So we can find the slope as ,
[tex]\implies slope = \dfrac{y_2-y_1}{x_2-x_1}\\\\\implies slope = \dfrac{ 1-0}{0+1} \\\\\implies\boxed{\boxed{ slope = 1 }}[/tex]

whats the distributive property
Answer:
5n + 5a
Step-by-step explanation:
This would be your simplified algebra expression.
Answer:
The distributive property tells us how to solve equations in the form of a(b + c). The distributive property is sometimes called the distributive law of multiplication and division. Normally when we see an equation like this … 4(8+3) distributive property format 4(8+3) -> 4(11) -> 44 we just evaluate what’s in the parentheses first, then solve it: 4(8+3)=4x8 + 4x3=44 These are the 2 methods
