The probability of rolling any specific number is 1/6. The expected number of points is found from:
E(points) = (1/6 * -1) + (1/6 * -2) + (1/6 * -3) + (1/6 * 4) + (1/6 * 5) + (1/6 * 6)
= 9/6 = 1.5 points
<u>Answer:</u>
D. Urvi multiplied with the reciprocal of the dividend instead of the reciprocal of the divisor.
<u>Step-by-step explanation:</u>
We are given that Urvi solved a fraction division problem using the rule “multiply by the reciprocal.”
The "multiply by the reciprocal” states that you take the reciprocal of the divisor (denominator) and multiply with the dividend (as it is).
But here we can see from the calculations made by Urvi that she took the reciprocal of the dividend and not the divisor.
Therefore, the correct answer option is D. Urvi multiplied with the reciprocal of the dividend instead of the reciprocal of the divisor.
Answer:
Step-by-step explanation:
trg CDE ,<C=<E=(180-20)/2=80
trg ABC,<C=80
<A=180-(80+52)=180-132=48
so <F=<A=48 grades
Answer:
Home Depot spent $1053 more than Lowes.
Step-by-step explanation:
Lowes Manager: 185 * 27 = 4,995
Home Depot Manager: 36 * 168 = 6,048
6048 - 4995 = 1053
Answer:
4x +3y = 7; 1 ≤ x ≤ 9; 1 ≤ y ≤ 9
(x, y) = (1, 1)
Step-by-step explanation:
If you simply add the numbers, you have ...
(x+y) +(3x+2y) +8 +9 = 24
This simplifies to ...
4x +3y = 7
Perhaps the other "equations" in the "system of equations" are the constraint inequalities ...
The smallest possible value of both x and y is 1, which would satisfy this equation:
4·1 + 3·1 = 7
Using the expression (x+y) +(3x+2y) +8 +9 = 24, suitable values for x and y are 1 and 1.

We have written one equation, which in this context only has one solution for the two variables. It seems likely that we need to know more about the game card in order to write a system of equations.
