Answer:
In the first draw of the trial, the card drawn can be a king of spades, clubs, diamonds, or hearts. So, the size of the sample space is 4 in the first draw. In the second draw, the sample space size becomes 42 = 16.
Step-by-step explanation:
Plato answer !! Hope this helps !! <3
The sample space consists of 16 possible outcomes.
We have trial in which you draw one card twice from a set of 4 kings: spade, club, diamond, and heart and the card is replaced in the set before the second draw.
We have to find the sample space of the trial.
What is Sample Space?A sample space of any event is the set of total number of possible outcomes of that event.
The card is replaced in the set before the second draw.
After the card is drawn twice - the sample space set S will consist of-
4 x 4 = 16
Hence, the sample space consists of 16 possible outcomes.

The measure of an angle is 2.8.what is the measure of its complementary angle
Answer:
87.2º
Step-by-step explanation:
Complimentary angles total 90º
c + 2.8 = 90
c = 90 - 2.8
c = 87.2º
Answer:
87.2°Step-by-step explanation:
When angles are complementary, it means that they both add up to 90°.
In this case, one of the angles measures 2.8°.
So, to find the other one, we subtract 2.8 from 90.
90 - 2.8 = 87.2
The measure of the complementary angle is 87.2°

El promedio del 5 personas $ 20 si ingresan 3 personas con promedio de $ 60 ¿ cual es promedio del dinero de las personas
Answer:
El promedio de dinero de las personas es de $35 cada uno.
Step-by-step explanation:
Dado que el promedio del dinero de 5 personas es de $20 cada uno, para determinar, si ingresan 3 personas con promedio de $60 cada uno, cuál es promedio del dinero de las personas , se debe realizar el siguiente cálculo:
((5 x 20) + (3 x 60)) / 8 = X
(100 + 180) / 8 = X
280 / 8 = X
35 = X
Por lo tanto, el promedio de dinero de las personas es de $35 cada uno.

Answer:
peanut butter jelly sandwich
The work done by gravitational force is -51100 J
What is gravitational force?Gravitational force is the force of attraction between all masses in the universe. It is the weakest of all the natural forces. It depends on the mass and distance of the objects.
Given that, a labour has weight 50 kg and bricks carried weighted 20kg to the top of the tower of height 73 m, we need to find the work done by the gravitational force,
W = height × weight × gravity
W = 73 × (50+20) × 10
W = 73 × 70 × 10
W = 51100 J
Hence, the work done by gravitational force is -51100 J

Line segment TU has endpoints (-7,10) and (-6,-5). What is the length of TU to the NEAREST TENTH?
Answer: 15 units
Step-by-step explanation:
Given
The endpoints of the line segment are [tex](-7,10)\ \text{and}\ (-6,-5)[/tex]
The length of the line segment is given by the distance formula i.e.
[tex]d=\sqrt{\left( x_2-x_1\right)^2+\left( y_2-y_1\right)^2}[/tex]
Insert the values,
[tex]\Rightarrow d=\sqrt{\left( -6+7\right)^2+\left( -5-10\right)^2}\\\Rightarrow d=\sqrt{1^2+\left( -15\right)^2}\\\Rightarrow d=\sqrt{1+225}\\\Rightarrow d=15.0\ \text{units}[/tex]
Therefore, the length of line segment TU is 15 units
The ages of trees in a forest are normally distributed with a mean of 25 years and a standard deviation of 5 years.
Complete question is in comment section :
Answer:
68%
Step-by-step explanation:
Mean = 25
Standard deviation = 5
The percentage of trees between 20 and 30
20 trees = 1 standard deviation below the mean ; mean - 1(standard deviation)
25 - 5 = 20
30 trees = 1 standard deviation above the mean ;
Mean + 1(standard deviation) ;
25 + 5 = 30
This means, 20 and 30 lies ±1 standard deviation from the mean which according to the empirical rule is 68%
According to the empirical rule :

A bag contains 6 white marblesw and 4 black marbles.a marble is drawn from the bag and then a second marble is drawn without replacing the first one. what is the probability of drawing a white marble on the first draw and another white marble on the second draw
Answer:
60.5%
Step-by-step explanation:
60% white, 40% black
The first draw you have a 60% chance drawing a white marble, the second time you have a 55% chance since you already drew one in the first round. so i think it is 60.5%% chance drawing white on both rounds since I add 60+55=121. 121/200=60.5%
