For right triangles, use SOH CAH TOA.
Given angle is 27, given sides are 'x' and 20.
Which sides are given, opposite, adjacent, or hypotenuse?
opposite is across from angle(27) -----> unknown
adjacent is leg next to or touching the angle(27) -----> 'x'
hypotenuse is side across from right angle -----> 20
which trig ratio uses adjacent and hypotenuse?
CAH has both A for adjacent and H for hypotenuse.
Therefore use the cosine ratio.
Hello!
To find the lateral area you use the equation
You put in the values you know and you get 829.4
To find the surface area you use the equation
Put in the values you know and you get 1209.5
The answer is A
Hope this helps!
Just took the test this is the correct answer!
Answer:
H0 : μ = 18000
H1 : μ < 18000 - - - > Claim
Test value = - 3.578
Critical value = ±2.58
There is significant evidence to accept the claim that mean debt at graduation is less than $18000
Step-by-step explanation:
H0 : μ = 18000
H1 : μ < 18000
From the data:
Sample size, n = 30
Sample mean, x = 16298.37
The test statistic :
(16298.37 - 18000) ÷ (2605/sqrt(30))
−1701.63 / 475.60575
= - 3.578
The critical value :
Using the standard normal table;
Critical value at α = 0.01
Critical value = ±2.58
Decison region :
|test statistic | > |Critical value | ; reject H0
|3.578| > |2.58| ; We reject H0 and conclude that Mean debt at graduation is less than $18000
Answer: the first one is irrational because it is a repeating fraction.
the third is square root of 7 is less than 14/5
the fourth is negative 5 over 6, negative 5, negative 31 over 6, negative square root 26
Step-by-step explanation: Hope this helps !
