Answer:
1/20
Step-by-step explanation:
The only way it can equal 2 is if both spinners land on 1 because 1 + 1 = 2.
The probability of the 1st spinner landing on 1 is 1/4.
The Probability of the 2nd spinner landing on 1 is 1/5.
To find out the Probability of them landing together it would be 1/5 times 1/4 which equals 1/20.
Hey there!
y = -1/4x + 10
Looking for the amount of hours of sleep for an 8 year old, so x is 8.
Solve for y:
y = -1/4(8) + 10
y = -2 + 10
y = 8
The predicted number of average hours of sleep for an 8 year old is 3. 8 hours.
Hope this helps!
Answer:
Maria sent 7 messages
Bob sent 5 messages
Ahmad sent 45 messages
Step-by-step explanation:
Given that Maria, Ahmad, and Bob sent a total of 52 text messages during the weekend.
If Maria sent fewer messages than Bob, and Ahmad sent times as many messages as Bob
Since the exact figures were not given, then let make an assumption that Ahmad sent 9 times as many messages as Bob.
If Bob sent 5 messages, then, Ahmad will send 5 × 9 = 45 messages
Also, it is given that Maria sent fewer messages than Bob. Take 45 away from 52. That is,
52 - 45 = 7
Therefore,
Maria sent 7 messages
Bob sent 5 messages
Ahmad sent 45 messages

Answer:
156 cm³
Step-by-step explanation:
The volume of any prism is the product of the base area and the height of the prism. Here, we can take the "base" to be the front face of the assembly, and its "height" to be the 3 cm distance between the front and back faces.
The front face area is the sum of the triangle area and the rectangle area.
A = 1/2bh + LW
A = (1/2)(10 cm)(4 cm) + (16 cm)(2 cm) = 52 cm²
Then the volume is ...
V = Bh = (52 cm²)(3 cm) = 156 cm³ . . . . total volume of the two blocks
