Answer:
11 km/hr.
Step-by-step explanation:
Given information:
Simulated speed = 20/km/h
Time = 15 mins = 1/4 hr = 0.25 hr
Distance Covered as per simulated speed =
Position of Julian according to the app = .
Actual distance covered by the bike is
Formula for speed:
Therefore, the average speed of Julian is 11 km/hr.
Answer:
48 cm
Step-by-step explanation:
Given:
Distance of rod from the wall = 45 cm
Distance of rod from the light = 15 cm
Length of rod = 12 cm
We can see that <DAM and <BAF are equal
Also, <DMA and <BFM are equal because they are corresponding angles
To find the length of the shadow, let's take the equation
Where.:
DM = ½ of length of the rod = ½*12 = 6
A.F = 15 + 45 = 60 cm
AM = 15 cm
Therefore,
Cross multiplying, we have:
15 * B.F = 60 * 6
15 * B.F = 360
BF = 24 cm
The shadow on the wall =
2 * BF
= 2 * 24
= 48 cm
The shadow on the wall is 48 cm

Step-by-step explanation:
Given the data below :
Juice Mango Orange Apple Pineapple Grapefruit Grape
Proportion of Facings 0.1875 0.250 0.250 0.125 0.125 0.0625
In other to make the proportion of facing visible on the graph we multiply by 100; Hence,
Juice Mango Orange Apple Pineapple Grapefruit Grape
Proportion of Facings 18.75 2.50 2.50 1.25 1.25 6.25
Juice Mango Orange Apple Pineapple Grapefruit Grape
Observed Number of Sales 23 35 46 12 10 5
(a) Construct a single bar chart that contains both the expected proportion of sales based on the proportion of facings and the observed proportion of sales for each type of juice.
Using an online bar chart plotter, the proportion of facings by the blue bars and the red bars depicts the observalues for different type of juice Given.
Hence, from the plot, it could be clearly seen that the distribution of facing is different or not equal to the number of juice sold.
The barchart produced is attached below.
Answer:
(E) 0.83
Step-by-step explanation:
We will solve it using conditional probability.
Let A be the event that a TV show is successful.
P(A) = 0.5
A' be event that the show is unsuccessful
P(A') =0.5
Let B be the event that the response was favorable
P(B) = 0.6
Let B' be the event that the response was unfavorable/
P(B') = 0.4
P(A∩B) = 0.5 and P(A∩B') = 0.3
We need to find new show will be successful if it receives a favorable response.
P(A/B) =
= 0.5/0.6
= 0.833
