Step-by-step explanation:
(Vertical angles)
(Measure of minor arc is equal to the measure of it's corresponding central angle)
![\therefore m\widehat{AB} = m\widehat {DE} - m\widehat {BC} \\ \\ m\widehat{AB} =93 \degree - 38 \degree \\ \\ m\widehat{AB} =55 \degree](https://tex.z-dn.net/?f=%5Ctherefore%20m%5Cwidehat%7BAB%7D%20%3D%20m%5Cwidehat%20%7BDE%7D%20-%20m%5Cwidehat%20%7BBC%7D%20%20%5C%5C%20%20%5C%5C%20m%5Cwidehat%7BAB%7D%20%3D93%20%5Cdegree%20-%2038%20%5Cdegree%20%5C%5C%20%20%5C%5C%20m%5Cwidehat%7BAB%7D%20%3D55%20%5Cdegree)
Answer:
The error interval for x is:
[3.65,3.74]
Step-by-step explanation:
The number after rounding off is obtained as:
3.7
We know that any of the number below on rounding off the number to the first decimal place will result in 3.7:
3.65 3.66 3.67 3.68 3.69 3.70 3.71 3.72 3.73 3.74
( Because if we have to round off a number present in decimals to n place then if there is a number greater than or equal to 5 at n+1 place then it will result to the one higher digit at nth place on rounding off and won't change the digit if it less than 5 )
Hence, the error interval is:
[3.65,3.74]
Answer:
Answer is 0.5
Step-by-step explanation:
The text implies that the number of traffic accidents determines the number of ambulances required on the road. Hence, 1 traffic accident requires 1 ambulance.
The time slot and time of day remain same in both the text and the question.
The average or mean number of accidents is 1.1
QUESTION: What then is the probability that there is need for exactly 2 ambulances on that road and in that time frame?
In other words, what is the probability that there'll be 2 accidents on that road and in that time frame?
Since the mean number of accidents is 1.1, 2 is above the mean.
Probability of 1.1 accidents is 1, since that's the mean (expected value).
Probability of 2 accidents is 1/2 which is = 0.5
Answer:
154 because we multiply the 11in and 14 in to get 154 inches so h = 154 inches
Answer:
$13.60 for tip
$81.59 for total meal cost
Step-by-step explanation:
Meal = $67.99
tip is 20% so 0.20
67.99*0.20=13.60 tip
