Answer:
I can help you with 1, 2 and 3.
Step-by-step explanation:
1. 2x + 3y = 1470
Subtract 2x from both sides: 3y= -2x+1470
Divide three from both sides: y= \frac{-2}{3}x +490
2. To graph it, you would first go to (0,490) because that is where the y-intercept is. Since slope is ride over run, you can either go up 2 left3 or down 2 right 3. You can proceed doing that until you have enough points to draw the line.
3. f(x)= -2/3x +490. This function means represents how many wraps are sold based on how many rolls are sandwich.
Well I'm still trying to solve the first question so I'll tell you the other answers
the answer for the second question is :
and for the third question :
Step-by-step explanation:
7 students were in the van so 187 - 7 = 180. 180 ÷ 4 = 45, there were 45 students on each bus. Not sure if this makes total sense, hope it helps
Answer:
Step-by-step explanation:
Given:
First Number = 97
Second Number =
We need to find the product of two numbers in Scientific notation.
Product of two numbers means we need to multiply two number.
Also The proper format for scientific notation is a x 10^b where a is a number or decimal number such that the absolute value of a is less than ten and is greater than or equal to one or, 1 ≤ |a| < 10. b is the power of 10 such that the scientific notation is mathematically equivalent to the original number.
Decimal points are moved until there is only one non-zero digit to the left of the decimal point. The decimal number results as a.
Number of decimal point moved needs to be counted. This number is b.
If decimal are moved to the left b is positive.
If decimal are moved to the right b is negative.
If decimal are not moved b = 0.
scientific notation of a number can be written as a x 10^b and read it as "a times 10 to the power of b."
Hence the product is;
Expressing in Scientific Notation form we get
Hence the Answer is .
Answer:
a. 7/22
b. 28/33
c. 7/22
d. dependent events
Step-by-step explanation:
The total number of cards is given as 7 + 5 = 12.
The probability if a card being green on the first pick, P(G) = 7/12
The probability of a card being yellow on the first pick, P(Y) = 5/12
Because there is no replacement, the card are going to be short by one card. Therefore, the second pick will be like this:
P(GG) = ( 7/12×6/11)
P(GY) = ( 7/12 × 5/11)
P(YG) = ( 5/12×7/11)
P(RR) = ( 5/12 ×4/11)
a. P (G1 and G2) = ( 7/12×6/11)
= 7/22
b. P( At least one is green) = ( 7/12×6/11) + ( 7/12 × 5/11) + ( 5/12×7/11)
= 28/33
c. P(G2G1) = 7/22
d. the events are dependent. They do not give the same result.
