What is the value of mza+mZb?<br>a<br>124°<br>O<br>34<br>56<br>90°<br>180°<br>om​
alexira [117]

Answer:

90°

Step-by-step explanation:

180-124=56 so angle a is 56 and a=c so c would also be 56 next you'd have to add the right angle with angle c. 90+56=146 then to get the angle for b you would have to subtract 180-146 which is 34

34+56=90°

Angles STU and UTV combine to form right angle STV. Which expression could be used to find the measure,in degrees,of angle UTV?
Sergeu [11.5K]
STV=STU+UTV

But,
STV=90° and STU = 75°

Therefore,
90=75+UTV => UTV = 90-75

Therefore, expression A is the one that can be used to find UTV.

Tom is throwing darts at a target. In his last 30 throws, Tom has hit the target 20 times. You want to know the estimated probab
Musya8 [376]

Each scenario can be used to simulate probability, and there are 3 correct scenarios and 2 incorrect scenarios in the list of options

<h3>How to categorize the simulations?</h3>

From the question, we have the following parameters:

  • Number of throws = 30
  • Number of hits = 20

This means that the probability of hit is:

P(Hit) = 20/30

Simplify

P(Hit) = 2/3

Using the complement rule,

P(Miss) = 1/3

The above means that the simulation that represents the situation must have the following parameters:

  • P(Success) = 2/3
  • P(Failure) = 1/3
  • Number of experiments = 3

Using the above highlights, the correct scenarios are:

  • Rolling a die three times with numbers 1 to 4 representing a hit
  • Spinner a spinner of 3 equal sections three times with two sections representing hit
  • Spinner a spinner of 6 equal sections three times with four sections representing hit

Morgan uses 2 oz of dog shampoo to bathe her dog each week. After 4 wk, 34 oz of shampoo remains.
Flauer [41]
The amount of shampoo required by Morgan each week to bathe her dog = 2 oz
So
The amount of shampoo required by Morgan in 7 days to bathe her dog = 2 oz
The amount of shampoo remaining after 4 weeks = 34 oz
So the amount of shampoo remaining after (4 * 7) days = 34 oz
The amount of shampoo remaining after 28 days = 34 oz
The amount of shampoo that Morgan uses in 28 days = (2/7) * 28 oz
                                                                                      = 2 * 4 oz
                                                                                      = 8 oz
Then
8 oz of shampoo is required by Morgan in = 28 days
Then
34 oz of shampoo will be used in = (28/8) * 34 days
                                                      = 7 * 17 days
                                                      = 119 days
So
The total number of
days before the bottle becomes empty = 119 + 8 oz
                                                               = 127 days
