For a standard double six set domino and starting with a double six,
6|6 followed by 6|5 followed by 5|5 followed by 5|4 followed by 4|4 followed b 4|4 followed by 4|3 followed by 3|3 followed by 3|2 followed by 2|2 followed by 2|1 followed by 1|1 followed by 1|0 followed by 0|0
The last number is 0
I’m pretty sure the value is 80 because that’s a 90° angle. 90 minus that 10 leaves 80
Answer:
The probability is
Step-by-step explanation:
From the question we are told that
The population mean is
The standard deviation is
Given that the amounts of nicotine in a certain brand of cigarette are normally distributed
Then the probability of randomly selecting a cigarette with 0.305 grams of nicotine or less is mathematically represented as
Generally
So
From the z-table(reference calculator dot net ) value of

Step-by-step explanation:
Actually, it isn't that hard. Remember the difference of squares? (a + b)(a - b) = a² - b² and in this case 9 is a and 4x is b so our answer is 81 - 16x².
Answer: The area of the enlargement is 315cm.
Step-by-step explanation:
If the picture has 35cm as the area and it has a length of 7cm then we can find the width by dividing the area by the length.
w= 35/7
w = 5
So in this care the width of the picture in 5cm.
Now is saying that the picture's length has been enlarge or been dilated to 21 cm. To get from 7cm to 21cm you will have to multiply by 3.
In this situation, we will have to multiply the original picture's width by 3 to find it enlargement.
w= 5*3 = 15
The width is 15cm and the length is 21cm so multiply them to find the area.
A = 15 * 21
A = 315cm
