Answer:

334/667

Step-by-step explanation

chances of getting heads is 1/2

chances of getting an even number is 333/666

simply add them up

Answer:

1/4

Step-by-step explanation:

i’m assuming u meant a 6 sided die. the probability of flipping a heads would be 1/2. the probability of rolling an even number is 3/6. 3/6 times 1/2 is 3/12 or 1/4

Answer:

V = 136.1

Step-by-step explanation:

Use the formula [tex]V = \frac{1}{3}\pi r^{2} h[/tex]

The solution is,  the volume of the cone is 136.2inch^3.

The formula for the volume of a cone is ⅓ r2h cubic units, where r is the radius of the circular base and h is the height of the cone.

here, we have,

A cone has a radius of 5.1 inches

and a height of 5 inches.

we know,

Volume =  ⅓ r²h

             =136.2inch^3.

Hence, The solution is,  the volume of the cone is 136.2inch^3.

Answer:

2/8 < 7/8

Step-by-step explanation:

Since the denominators are the same, we compare the numerators

2<7  so

2/8 < 7/8

Answer:

According to the picture, we can have the function form as:

y = ax^2 + bx + c

The y-intercept is (0, 2) => c = 2

=> y = ax^2 + bx + c

The x-intercept is (-2, 0)

=> 4a - 2b = 0 (1)

The graph goes through (1, 1.5)

=> a + b + 2 = 1.5

=> a + b = -0.5 (2)

From (1) and (2)

=> 4a - 2(-a - 0.5) = 0

=> 6a + 1 = 0

=> a = -1/6 => b = -0.5 - (-1/6) = -1/2 + 1/6 = -15/30 + 5/30 = -10/30 = -1/3

=> y = (-1/6)x^2 -(1/3)x + 2

Answer:

Step-by-step explanation:

Final answer:

The distance between the points (-4,8) and (12,8) on a coordinate plane is 16 units, calculated by finding the difference between the x-coordinates since the y-coordinates are the same.

Explanation:

The question asks for the distance between the points (-4,8) and (12,8) on a coordinate plane. To find this distance, we can use the formula for the distance between two points in a plane:

d = √((x2 - x1)^2 + (y2 - y1)^2)

Since the y-coordinates are the same (8 and 8), the distance is simply the difference between the x-coordinates:

d = 12 - (-4) = 12 + 4 = 16

Therefore, the distance between the points (-4,8) and (12,8) is 16 units.

Answer:

ABC = 31

Step-by-step explanation:

Angle AOC and ABC have the angle theorem: the angle subtended at the centre of the circle is double the angle at the circumference. Its quite hard to realise the layout, because angle AOC isn't between points A and C. If angle AOC moved to the right side of line AB, it would be easier to see. Of course we cannot do this, otherwise angle AOC wouldn't be the middle anymore. Hope this helped

(a). The angle AOD is 62 degrees.

(b). The angle ABC is 31 degrees.

(a). From given diagram, It is observed that triangle AOD is a right angle triangle.

The sum of all three angles in triangle is equal to 180 degrees.

           [tex]\angle A +\angle O + \angle D = 180\\\\90 +\angle AOD +28=180\\\\\angle AOD=180-90-28=62[/tex]

(b). The central angle theorem states that the angle subtended by an arc at the center of the circle is double the angle subtended at any point on the circumference of the circle.

        [tex]\angle ABC = \frac{1}{2} \angle AOD\\ \\\angle ABC=\frac{1}{2}*62=31[/tex]

Answer:

A. 9.85 inches

Step-by-step explanation:

In the graph we can see that 1 month has a rainfall of 0.4 in, 2 months have a rainfall of 0.5 in, 1 month has a rainfall of 0.6 in, 2 months have a rainfall of 0.85 in, 1 month has a rainfall of 0.95 in, 2 months have a rainfall of 1.0 in, 2 months have a rainfall of 1.05 in and 1 month has a rainfall of  1.1 in.

The total amount of rainfall in the desert that year was: 0.4 + 2*0.5 + 0.6 + 2*0.85 + 0.95 + 2*1.0 + 2*1.05 + 1.1 = 9.85 inches

Answer:

The last case shows that the two triangles are congruent by SSS congruency theorem

Step-by-step explanation:

Triangles A B C and A D C share common side A C. The lengths of A B and A D are congruent. The lengths of B C and D C are congruent.

With this case.  You have sides  AB = AD,  BC = DC,  and then can conclude that AC= AC by reflexive property  because AC is the common side.

so triangle ABC = triangle ADC  by SSS congruency

----------------------------

CASE 1.) Triangles A B C and D E C are connected at point C. Angles A B C and C E D are right angles. The lengths of sides A B and E D are congruent.  ---- You would only know  one pair of sides and one pair of angles that are congruent.

CASE 2.)  Triangles A B C and D E C are connected at point C. The lengths of sides A B and D E are congruent. The lengths of sides B C and C D are congruent. -----  You would only know 2 pairs of congruent sides.  

CASE 3.)Triangles A B C and D E C are connected at point C. The lengths of sides A C and C E are congruent. Angles B A C and C E D are congruent.  ---- You would  only know a pair of angles and a pair of sides.  Not enough for congruency.

CASE 4.) Triangles A B C and A D C share common side A C. The lengths of A B and A D are congruent. The lengths of B C and D C are congruent.

Answer:

ik can u make a question and put ur face on da question so i can see you?????

Step-by-step explanation:

a. The experimental probability of landing on a 2 is 1/6.

b. The experimental probability of not landing on a 6 is 5/6.

c. The experimental probability of landing on a 2 (1/6) closely aligns with its theoretical probability (1/6).

d. The experimental probability of not landing on a 6 (5/6) also closely aligns with its theoretical probability (5/6).

a. To find the experimental probability of landing on a 2, divide the number of times it landed on a 2 (four times) by the total number of trials (24 times). Thus, [tex]\( P(\text{landing on 2}) = \frac{4}{24} = \frac{1}{6} \).[/tex]

b. To find the experimental probability of not landing on a 6, subtract the experimental probability of landing on a 6 (3/24) from 1. Thus,[tex]\( P(\text{not landing on 6}) = 1 - \frac{3}{24} = \frac{5}{6} \).[/tex]

c. Comparing the experimental probability of landing on a 2 (1/6) with its theoretical probability (1/6) shows that they closely match, indicating a consistent outcome.

d. Comparing the experimental probability of not landing on a 6 (5/6) with its theoretical probability (5/6) reveals a close alignment, confirming the reliability of the experimental results.

In summary, experimental probabilities were determined by dividing the favorable outcomes by the total number of trials. The comparison with theoretical probabilities indicates the reliability of the experimental data, as the values closely match in both cases. This alignment strengthens the validity of the experimental results and the predictive power of theoretical probabilities in this scenario.

Answer:

107.5 miles

Step-by-step explanation:

We can use the formula d = rt (distance = rate · time) to find the distance travelled.

We know that,

r = 43 mph

t = 2.5 hrs

Plug these values into the formula to get your answer.

43 · 2.5 = 107.5 miles

Answer:

Frank drove a total of about 107 miles.

Step-by-step explanation:

Okay...

2.5 hours at 43 miles per hour.

43 x 2 = 86

and for .50 we can say half which is about 21 or 22 miles.

So,

86 + 21 = 107

D = 107
