Answer:
The second one, 160
Step-by-step explanation:
3+3+5+8=19, and 380/19=20 so each unit is 20cm
8 is the largest side --> 8*20 = 160
T = 2
1. Divide both sides by 2
--> t / 2
=
2. Square both sides
-->
/ 4
= m / k
3. Multiply both sides by k
--> m = k
/ 4
Answer:
The researcher should reject the null hypothesis at the significance level
Step-by-step explanation:
If the P-value is smaller than the significance level, the null hypothesis is rejected
If the P-value is the same as the significance level, the null hypothesis is rejected
Answer:
75
Step-by-step explanation:
f(x)=-x^2-10x
f(-5)=(-5)^2-10(-5)
f(-5)=(-5)(-5)+50
f(-5)=25+50
f(-5)=75
Answer:
2 units
Step-by-step explanation:
Given data
The points are (2, 3) and (2, 5)
x1= 2
y1= 3
x2= 2
y2= 5
substitute into the distance between two points formula
d=√((x_2-x_1)²+(y_2-y_1)²)
d=√((2-2)²+(5-3)²)
d=√(2)²)
d=√4
d= 2 units
Hence the length is 2 units
