Answer:
Number of Cucumbers = 12
Number of Tomatoes = 4
Step-by-step explanation:
Let number of cucumber be c and number of tomatoes be t
Since he has room for 16 plants, we can write:
c + t = 16
He wants to plant 3 times as many cucumbers as tomatoes. We can write:
c = 3t
We can substitute this in 1st equation and solve for t:
c + t = 16
3t + t = 16
4t = 16
t = 16/4 = 4
And c = 3t
c = 3(4) = 12
Number of Cucumbers = 12
Number of Tomatoes = 4
X+y=4000....(1)
10x+6y=340*100⇒5x+3y=17000......(2)
(2)- 3*(1)⇒ 2x=5000⇒x=2500,y=4000-2500=1500
Answer:
4 mechanical pencils
Step-by-step explanation:
Each notebook is worth $2.99
So buying 3 of the notebooks would leave her with $8.97
Then, $15.00 - $8.97= $6.05
Answer:
0.07
a. the distribution will be a normal distribution.
c. we would suspicious ins there is a 2 % chance of getting the required value.
Step-by-step explanation:
Let the number of times, t be = 50
Assuming that the die is fair
standard deviation = 1.71
mean = 3.5
suppose we want tp find the probability of a 2 showing. The solution becomes:
probability = 
c. the mean of rolls will be 0.07
Answer:
The mass of the grains = 120 ± 1 g
Step-by-step explanation:
we are given the following:
Total mass of container + grains = 185 grams
Mass of container = 65 grams
Therefore, mass of grains is calculated as follows:
Mass of grains = ( Mass of container + grains) - mass of container
= 185 - 65 = 120 grams.
since the scale has an absolute uncertainty of 1 g, the mass of the grains is written as 120 ± 1 g
