Answer:
1
Step-by-step explanation:
4a^4 -2b^2 +40
a=2
b=7
4(2)^4 -2(7)^2 +40
PEMDAS is what your gonna use to solve this you go from right to left
First is P which is parentheses which is none
second is E which stands for exponents
4(32)-2(49)+40
now MD multiply or divide
128-98+40
now add or subtract
30+40
last one
70 this is your answer i hope
<h2>
Answer: 20°</h2>
<h3>
Step-by-step explanation:</h3>
Supplementary angles sum up to 180 °
Complementary angles sum up to 90°.
The supplement of 110° = 180° - 110° = 70°
The complement of 70° = 90° - 70° = 20°
<u>Simplier version:</u>
The complement of the supplement of 110° = (90° - (180° - 110°))
= 20°
Answer:
95% confidence interval: (2.784,3.176)
Step-by-step explanation:
We are given the following information in the question:
Sample size, n = 25
Sample mean = $2.98
Standard error = $0.10
Alpha = 0.05
95% confidence interval:
Putting the values, we get,
Slope is 4/5
The equation is Y = mx + b
M represent the slope
In your equation, 4/5 is the slope.
