Answer:
Monday: 5x + 14
Tuesday: Average is about 55.77 and Median is 56
Step-by-step explanation:
To combine like terms means to add or subtract the terms with similar variables. So I did as such to find the answer.
24 - 10 = 14 and 7x - 2x = 5x
The average is found by dividing the sum of all values in the list by the number of list options. The median is the value found in the middle of the list.
The picture in the attached figure
step 1we know that
It is given that AD and BD are bisectors of ∠CAB and ∠CBA respectively.
Therefore,
x = ∠CAB/2 -----> equation 1
y = ∠CBA/2 -----> equation 2
step 2In triangle ABC,
∠CAB + ∠CBA + ∠ACB = 180° ----> [The sum of all three angles of a
triangle is 180°]
∠CAB + ∠CBA + 110° = 180°
∠CAB + ∠CBA = 180° - 110°
∠CAB + ∠CBA = 70° ------> divide by 2 both sides
∠CAB/2 + ∠CBA/2 = 70/2 -------> equation 3
substitute equation 1 and equation 2 in equation 3
x+y=35
hence
the answer isx+y =35°
⇒ x + y = 35° ...[From equation (1) and (2)]
Answer:
90% confidence interval: (70.41,86.89)
Step-by-step explanation:
We are given the following in the question:
Point estimate = 78.65
Margin of error, E = 8.24
Confidence level = 90%
Significance level = 10%
Formula:
Putting the values, we get,
(70.41,86.89) is the required 90% confidence interval.
Answer:
$22.70
Step-by-step explanation:
$80.45-$20.50=$59.95. $59.95-$37.25= $22.70.
hope i helped.
