Answer:
2.29*20 = 45.80 and 3.49*35 = 122.15.
Step-by-step explanation:
Answer:
Number line with open circle on 2 and shading to the right.
Step-by-step explanation:
The key words in the question were <em>more than</em> 5. So the debate club needs more than 2 more members. Closed circles mean that a value can also be equal to the number they're on. A closed circle on 2 would be incorrect because it says that the number of members the debate club needs can include two, but the value must be more than two.
So now it's narrowed down to the last two options. But since we know that they need more than 5 members, and not less, the shading will be on the right. So it's the last option.
If they are replaced, then the two events become independent of each other.
So, it becomes, what is the probability that you will pick a black card? Since there are an equal amount of red and black, you will have 1/2 chance.
Now, what is the probability of selecting a heart? Well, we have 4 suits, so you'll have a 1 in 4 chance at selecting a heart.
Since we want them simultaneously, we have to multiply them together to yield: 1/8
Answer:
a. 0.71
b. 0.9863
Step-by-step explanation:
a. From the histogram, the relative frequency of houses with a value less than 500,000 is 0.34 and 0.37
-#The probability can therefore be calculated as:
Hence, the probability of the house value being less than 500,000 is o.71
b.
-From the info provided, we calculate the mean=403 and the standard deviation is 278 The probability that the mean value of a sample of n=40 is less than 500000 can be calculated as below:
Hence, the probability that the mean value of 40 randomly selected houses is less than 500,000 is 0.9863
