Answer:
Step-by-step explanation:
a I’m pretty sure
Yes. Here's an example : I used 4 gallons of gas and drove 28 miles. The ratio is 4gallons for every 28 miles. 4 gallons: 28 miles.
Let the smaller number be x.
larger number: 22+x
x+(x+22)=62
2x+22=62
2x=62-22
2x=40
x=40/2
x=20
The smaller number is 20 and the bigger number is 22+20= 42
Hope I helped :)
Put (a+h) where x is and simplify to the extent you desire.
f(a+h) = (a+h)^2 +3(a+h) +5
= a^2 +2ah +h^2 +3a +3h + 5
f(a+h) = a^2 +3a +5 +h(2a +3) +h^2
Answer:
+2.718
Step-by-step explanation:
from the question,
the sample size is 12
therefore the degree of freedom,
df = 12 - 1
= 11
alpha = 1 - 0.98
= 0.02
this is because the confidence level is 98%
under the t distribution table, a degree of freedom of 11 and 0.02 alpha level = <em>2.718</em>
<em>the</em><em> </em><em>crit</em><em>ical</em><em> </em><em>valu</em><em>e</em><em> </em><em>t</em><em>*</em><em> </em><em>=</em><em> </em><em>2</em><em>.</em><em>7</em><em>1</em><em>8</em>
