Answer:
0.93382
Step-by-step explanation:
Let
The event where a car has air conditioning (ac) be A
The event where a car has an automatic transmission be B
[tex]P(\text{Car has ac and cars that don't have automatic transmission})=P(A\cap B')=\dfrac{71}{136}[/tex]
[tex]P(\text{Car has car has an automatic transmission and no ac})=P(B\cap A')=\dfrac{56}{136}[/tex]
[tex]P(\text{Car has no ac and cars that don't have automatic transmission})=P(A'\cap B')=\dfrac{9}{136}[/tex]
The probability of a chosen car which has ac or automatic transmission or both
[tex]P(A\cup B)=1-P(A\cup B)'\\\Rightarrow P(A\cup B)=1-P(A'\cap B')\\\Rightarrow P(A\cup B)=1-\dfrac{9}{136}\\\Rightarrow P(A\cup B)=0.93382[/tex]
The probability that a randomly selected car had automatic transmission or air conditioning or both is 0.93382
Justin’s mom just had a baby that weigh 8 pounds. Justin insisted that the baby weighed 128 ounces. Is Justin correct or incorrect? Justify your answer.
PPPPPLLLLLLLLLLLLLEEEEEEEEEEEEESSSSSSSSSEEEEEEEEEEEEEEEEE HELP ASAP PPPPLLLLLLEEEEEEEEEEEEEEEEEEEEEEEEEEEESSSSSWEEEEEEEEeeeeeeEEEE
Answer:
Yes, Justin is correct.
Step-by-step explanation:
1 pound equals 16 ounces, so if you multiply 16×8, it equals 128 ounces.
Answer:
read explanation
Step-by-step explanation:
convert pounds to ounces
using the measurement system, for every 16 ounces there is 1 pound
the baby weighs 8 pounds and justin says its equal to 128 ounces.
128 divided by 16 is indeed 8 so therefore justin is right, mom
geesh listen to your kids more

You can find the constant of proportionality of the ratio of the price to the number of bouquets from the table by dividing them. For example, it you divide 9 by 3 or 18 by 6, you get 3. Therefore, you know that every bouquet is 3 dollars. :) Hope this helps

What is the value of x?
Enter your answer in the box.
x = ____
Answer:
X=32
Step-by-step explanation:
since it is equilateral, all the angles are the same so they equal 60 , because those are the only possible angle measurements that an equilateral triangle can have.
we know that all the angles are equal to 60 so we set up an equation
2x-4=60
2x=64
x=64/2
x=32
Can you guys please help me out
Answer:
18
Step-by-step explanation:
xy = x times y
in our case, it is 6 times 3
so 18
The distance Train A travels is represented by d = 69t, where d is the distance in kilometers and t is the time in hours. The distance Train B travels at various times is shown in the table. What is the unit rate of each train? Which train is going faster?
If d is distance measured in km and t is time measured in hours, then d = 69t tells you that train A is moving at a rate of 69 km/h.
Why? If t = 1, then d is the distance it moves in 1 hour, and that's precisely the unit rate. It's the rate at which the distance changes when 1 unit of time passes.
For train B, use the info in the given table. In 1 hour (between hours 4 and 5), the train covers a distance of 375 km - 300 km = 75 km. So it's moving at a rate of 75 km/h.
It should be clear which train is faster.
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
[tex]d(A) = 69t[/tex]
[tex]d(B) = 75t[/tex]
The unit rate is the coefficient of t which is the slope of the line because the trains distance traveled equation are linear.
Thus :
Train A's unit rate is 69 km per hour.
And
Train B's unit rate is 75 km per hour.
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
Train B is going faster because its unit rate is greater than Train A's unit rate .

Which describes the correlation shown in the scatterplot?
Answer:
There is no positive or negative correlation
Step-by-step explanation:
the x-values are increasing but the y-values are staying the same so if you drew a line through correlation... the slope would be around 0

How can you subtract mixed numbers when the fraction in the first mixed numbers is less than the fraction in the second mixed number?
When subtracting mixed numbers, if the fraction in the second mixed number is larger than the fraction in the first mixed number, rewrite the first mixed number by regrouping one whole as a fraction. Alternatively, rewrite all fractions as improper fractions and then subtract.

Step-by-step explanation:
If two triangles are congruent, then they will have the exact same sides and angle measures.
AB=3x+1
BC=6
DE=2x
Solve for X by making 2x=6 because DE and BC are corresponding sides, indicating they are equal.
x=3, plug that in
AB=10

61. The 2003 Statistical Abstract of the United States reported the percentage of people 18 years of age and older who smoke. Suppose that a study designed to collect new data on smokers and nonsmokers uses a preliminary estimate of the proportion who smoke of .30. a. How large a sample should be taken to estimate the proportion of smokers in the population with a margin of error of .02
Answer: Required minimum sample size = 2017
Step-by-step explanation:
Formula : Sample size(n) for population proportion(p):
[tex]n= p(1-p)(\frac{Z^c}{E})^2[/tex] , where E = Margin of error
If p = proportion of smokers
Given: p =0.30 and E=0.02
[tex]z^c[/tex] for 95% confidence level = 1.96
So,
[tex]n=0.30(1-0.30)(\dfrac{1.96}{0.02})^2\\\=0.30(0.70)(98)^2\\\\=2016.84\approx2017[/tex]
Hence, required minimum sample size = 2017
