Answer:
y = -x + 4
Step-by-step explanation:
The point-slope formula for a straight line is
y – y₁ = m(x – x₁)
x₁ = -1; y₁ = 5; m = -1 Substitute the values
y – 5 = -1(x + 1) Remove parentheses
y – 5 = -x - 1 Add 5 to each side
y = -x + 4
The graph is a straight line with a y-intercept at y = +4 and a slope = -10/10
= -1.
Is the question complete or is that 0.25?
Hi.. U should do like this
4/5 mile in 50 min
X mile in 60 min
X=5/4 mile
You would just decide both sides by 2.
-x = -9/3 ⇨ -3
Since both numbers are negative, the product becomes a positive.
x=3
Hope this helped!
Answer:
The value is
Step-by-step explanation:
From the question we are told that
The mean of Jo cows is 
The standard deviation of Jo cow is 
The mean of Val cows is 
The standard deviation of Val cows is 
The sample size for both Val and Jo is n = 25
Let assume that the level of significance is 
Generally from the normal distribution table the critical value of
is
Generally the margin of error is mathematically represented as
Hence margin of error for Jo is
=>
