Answer:
The sample size is too small and will show a large variation.
The sample size is too small and can lead to false inferences.
A larger sample will give more reliable information.
Step-by-step explanation:
-In statistical sampling, sample size is of critical importance.
-A large sample size increases the accuracy of mean values as it eliminates or flattens out outliers.
-A large sample size also leads to a lower margin of error as the confidence level increases.
-The is greater precision when a larger sample size is used.
Answer:
-1/8
Step-by-step explanation:
The given expression is y⁻³
We want to find the value of the expression when y = -2
Thus;
At y = -2, we have; -2⁻³
According to law of exponents, x⁻⁴ = 1/x⁴
Thus; -2⁻³ = -1/2³ = -1/8
The equation x=2t-1 represent the x-coordinate. To get the value of x, substitute t with -1.
That is: x = 2(-1) - 1
= -2-1
= -3
Likewise, the equation y=t∧-3 represent the y-coordinate. Substituting t with -1,
y = (-1)∧-3
= -1
The point that correspond to t=-1 is (-3,-1).
$1.47 = $9.80P
$1.47/$9.80 = $9.80P/$9.80
P = 0.15
The percent of tip is 15%
Today’s Lunch $12.60 x 15% = $12.60 x 0.15 = $1.89
She leaves $1.89 tip.
Answer:
As you can see, these are all set up in slope intercept form (with a y-intercept of 0). These equations are called "direct variation" because y varies directly with x. If x increases, then y increases as well. If x decreases, then y decreases.
