Answer:
H 0 : p ≤ 0.4 H a : p > 0.4
And based on the alternative hypothesis we can conclude that we have a right tailed test
Step-by-step explanation:
Data given
n=300 represent the random sample size
estimated proportion of people with cats
is the value that we want to test
represent the significance level
z would represent the statistic
represent the p value
Null and alternative hypothesis
We want to test if the true proportion of people with cats is higher than 0.4, so then the best alternative is:
Null hypothesis:
Alternative hypothesis:
H 0 : p ≤ 0.4 H a : p > 0.4
And based on the alternative hypothesis we can conclude that we have a right tailed test
The statistic is given by:
(1)
Replacing we got:
I pretty sure the answer would be negative because it not a full degree of temperature yet because its a decimal
Steel balls are 1.5 pounds, brass are 2 pounds
Answer:
19 is the answer
Step-by-step explanation:
3x - 4y
= <em>3</em><em> </em><em>×</em><em> </em><em>5</em><em> </em><em>-</em><em> </em><em>4</em><em> </em><em>×</em><em> </em><em>(</em><em>-1</em><em>)</em>
= <em>1</em><em>5</em><em> </em><em>+</em><em> </em><em>4</em><em> </em>
= <em>1</em><em>9</em>

Answer:
D
Step-by-step explanation:
The given line's equation is in slope-intercept form:
y = mx + b
where m = -4 is the slope, and b = -1 is the y-intercept.
The slope of the perpendicular line will be ...
-1/m = -1/(-4) = 1/4
You want the point-slope equation for the line, which is ...
y -k = m(x -h) . . . . line with slope m through point (h, k)
Your equation will have m=1/4, (h, k) = (-2, 7), so it will be ...
y -7 = 1/4(x +2)
