Answer:
a. y = x - 2
Step-by-step explanation:
y = a.x + b
from the graph: x = 0, y = -2 --> b = -2
x = 2, y = 0 --> 0 = a.2 -2 --> a = 1
The answer is 49 because x = 1/7 and 1/7^-2 =49
Answer:
Yes, because the quotient of Fraction 1 and 4 over 5 ÷ Fraction 3 over 4 is 2 and 2 over 5
Step-by-step explanation:
Jade used Fraction 3 over 4 yard of fabric to make a scarf. Can she make 2 of these scarves with Fraction 1 and 4 over 5 yards of fabric, and why?
Representing the above expression Mathematically
3/4 yard = 1 scarf
1 4/5 yards of fabric = x
Cross Multiply
3/4x = 1 4/5 × 1
x = 9/5/ 3/4
x = 9/5 ÷ 3/4
x = 9/5 × 4/3
x = 12/5 scarves
x = 2 2/5 scarves
Hence, the correct option is :
Yes, because the quotient of Fraction 1 and 4 over 5 ÷ Fraction 3 over 4 is 2 and 2 over 5
Answer:
3.25
Step-by-step explanation:
2 + d = 2 - 3 (d - 5) -2
d= -3d+15-2
4d=13
d= 13/4= 3.25
Answer: 0.0766
Step-by-step explanation:
Let x be the random team scores.
Given: Mean = 76
Standard deviation = 8.4
We assume that x follows normal distribution.
The probability that a random team scores less than 64 points = P(x<60)
Hence, the probability that a random team scores less than 64 points =0.0766
