Answer:
1. 500mg
2.A watermelon weighs about 3 (grams /(kilograms) 3.
3. 500 oranges
4. 30 weeks
5. 1500
Step-by-step explanation:
1. Therefore, 0.5 g=0.5*1000=500 mg
2. A watermelon weighs about 3 (grams /(kilograms) 3.
3.Weight of the box- 40 kg
Weight of 1 orange-80
Therefore, no. of total oranges=
40 kg=40000g
Now, 40000÷80
= 500
4. 500g x 2 is 1000 g and is 1kg
105-90 is equal to 15kg
500 x 30 is 15000 g is equal to 15 kg
5. divide by 4 to get the mass of a single bag and then multiply by 1000 to get to grams from kilograms
6/4=1.5
1.5*1000=1500
therefore a single bag of sugar weighs 1500 grams
Answer:
The Estimate the number of students who took the scores between 82 and 98 = 16
Step-by-step explanation:
<u><em>Explanation</em></u>:-
Given data The scores on a math test are normally distributed with a mean μ = 74
standard deviation of Population
S.D (σ) = 8
Let 'x' be the random variable of Normal distribution
<u><em>case(i)</em></u>:- when x = 82
<u><em>case(ii)</em></u>:- when x = 98
The probability that test scores between 82 and 98.
P(82≤x≤98) = P(1≤z≤3)
= P(z≤3) - P(z≤1)
= 0.5+A(3)-(0.5+A(1))
= A(3) -A(1)
= 0.4986 - 0.3413
= 0.1573
<u><em>Final answer</em></u>:-
The Estimate the number of students who took the scores between 82 and 98
= 100 X 0.1573 = 15.73 ≅16
6a^2 - 2 -6 a -5a = 0
6a^2 -11 a - 2 = 0
a = 2 , a= -1/6
X-5 and what are the flash cards do you mean?
We let x = Leslie's age
y = Bill's age
A. What expression represents Leslie's current age?
x = 8 + y
B. What expression represents bills age in 4 years. What expression represents Leslie's age in 4 years?
x+4 = 2(y+4)
C. What equation can you write based on the above given information?
You can have 2 linear equations with 2 unknowns.
D. What's bills current age? What is Leslie's current age?
x = 12 ----> LESLIE
y = 4 -----> BILL
