Answer: B. Isosceles Triangle
Step-by-step explanation:
isosceles triangle is a triangle that has two sides of equal length. Sometimes it is specified as having two and only two sides of equal length, and sometimes as having at least two sides of equal length, the latter version thus including the equilateral triangle as a special case.
Answer:
29.4≤μ≤32.6
Step-by-step explanation:
The datas given from the questions are as shown:
Number of people n = 24
Mean xbar= $31
Standard deviation σ = $6
Confidence Interval formula is expressed as:
CI = xbar ± Z(σ/√n)
Z value for 80% confidence interval is 1.282
Substituting the values into the Confidence Interval formula will give;
CI = 31 ± 1.282{6/√24}
CI = 31 ± 1.282(1.225)
CI = 31 ± 1.57045
CI = 31+1.57045 and 31-1.57045
CI = (29.42955, 32.57045)
CI = (29.4, 32.6) to 1dp
The confidence interval will be within the range 29.4≤μ≤32.6
ANSWER
EXPLANATION
To find the expression that is equivalent to
we must simplify it.
We apply the laws of exponents in the simplification.
First, let us share the cubic exponent for each factor in the numerator to obtain,
This gives us,
We simplify by applying the following law of exponent,
Our expression now becomes,
We simplify further to get,
This finally gives us,
The set-up 25/100= 50/? is incorrect.
The correct set-up should be ?/50= 25/100.
?= 50* (25/100)= 12.5.
The correct answer is 12.5~
Answer:
30x - 18
Step-by-step explanation:
6(5x - 3)
<em>Distribute the 6 to both monomials.</em>
6 * 5x = 30x
6 * -3 = -18
<em>Combine both final monomials.</em>
30x - 18
