Answer:
487
Step-by-step explanation:
The answer is 487 because you must look one place to the right of the whole number for the rounding digit on the right side of the decimal point which is 0. Then you round down since the digit is not greater than 5.
.
For the lines to be parallel the two angles need to be equal to each other:
128-x = x
Add 1x to both sides
128 = 2x
Divide both sides by 2:
X = 128/2
X = 64
Answer: x = 64
Answer:
H0 : μ = 0.5
H0 : μ > 0.5
Kindly check explanation
Step-by-step explanation:
H0 : μ = 0.5
H0 : μ > 0.5
We perform a right tailed test :
Sample proportion :
Number of games won, x = 142
Number of games, n = 250
phat = x / n = 142 / 250 = 0.568 = 56.8%
Yes, it is consistent
Test statistic :
(phat - p) * √Phat(1-Phat)/n
1 -Phat = 1 -0.568 = 0.432
(0.568 - 0.5) /√(0.568*0.432)/250
0.068 / 0.0313289
= 2.17
The Pvalue using the z test statistic :
Pvalue = 0.015
α = 0.03
Since ;
Pvalue < α ; We reject the null and conclude that teams tend to win more often when they play at home.
Answer:
5/hypotenuse, the square root of 7/ leg
Step-by-step explanation:
3^2+4^2=25 or 5^2. you use a^2+b^2=c^2. it would be one of the hypotenuses. If the missing number is a leg, you would do 4^2=3^2+x^2. 16=9+x^2, 7=x^2, so you plug in the numbers differently.
Answer:
a. Non proportional
b. Proportional
c. Non proportional
Step-by-step explanation:
Here, we want to determine if each situation is proportional or not
a) Non-proportional
This is because the amount y paid in a month will be;
y = 1400x + 150
Since the amount paid is not solely dependent on the number of months, then we do not have a proportional relationship
b) proportional
y = 3/4x
The value of y is dependent solely on that of x, so the relationship is proportional
c) non proportional
Since the value of y is not solely entirely dependent on x value, then the relationship is not proportional
