The probability of getting two red chips is:

P = 1/21.

The probability of getting a red chip is equal to the quotient between the number of red chips and the total number of chips.

There are 4 blue chips and 3 red chips, for a total of 7 chips.

For the first draw, the probability of getting a red one is:

p = 3/7.

For the second draw, now there are 2 red chips and 6 chips in total, so now the probability is:

q = 2/6 = 1/3

Then the joint probability, given by the product between the two individual probabilities, is:

P = q*p = (3/7)*(1/3) = 1/21.

The 48 flies of them will live longer than 21 days if there are 300 houseflies in the study.

It's the probability curve of a continuous distribution that's most likely symmetric around the mean. On the Z curve, at Z=0, the chance is 50-50. A bell-shaped curve is another name for it.

We have mean u = 18 days

SD = 3 days

X = 21 days

From the formula:

Z = (X - u)/SD

Z = (21 - 18)/3 = 1

P(x<21) = 0.84134

P(x>21) = 1 - P(x<21) = 0.15866

Number of flies = 300×0.15866 = 47.59 ≈ 48 flies

Thus, the 48 flies of them will live longer than 21 days if there are 300 houseflies in the study.

Answer:

m∠A = 90°

Step-by-step explanation:

In isosceles triangle base angles are congruent. That means we can equate measurments of angle B and angle C and solve for x!

m∠B = m∠C

11x - 10 = 7x + 10

4x - 10 = 10

4x = 20

x = 5

Now let's insert x back in the expressions for angles.

m∠B = (11x − 10)° = (11(5) − 10)° = 45°

m∠C = (7x + 10)° = (7(5) + 10)° = 45°

Sum of all angles in the triangle is 180°. Let's make an equation.

m∠A + m∠B + m∠C = 180°

m∠A + 45°+ 45° = 180°

m∠A  = 90°

Answer:

1.64

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2+b^2 = c^2  where a and b are the legs and c is the hypotenuse

6.6^2 + x^2 = 6.8^2

43.56+x^2=46.24

Subtract 43.56 from each side

x^2 = 46.24-43.56

x^2 =2.68

Take the square root of each side

sqrt(x^2) = sqrt(2.68)

x =1.637080554

To 3 significant digits

x = 1.64

Answer:

Step-by-step explanation:

       x = 1.637 mm

        We can use Pythagorean theorem, to find the unknown side for a right angled triangle.

The side opposite to 90 is the longest side and it is the hypotenuse.

Base² + altitude² = hypotenuse²

 x²     + 6.6²        = 6.8²

      x²  +  43.56  = 46.24

                     x²   = 46.24 - 43.56

                    x²    = 2.68

                      x   = √2.68

Answer:

Step-by-step explanation:

1) Let the unknown angle = x

   x +  43 + 90 = 180

Answer:

The probability of scoring fewer than 5 runs when they win is P = 0.19

How to find the probability?

We know that:

The probability of winning a game is p = 0.53

The probability of scoring 5 or more runs is q = 0.59

The probability of winning and scoring 5 or more runs is k = 0.43

Notice that the joint probability is different than the product of the individual probabilities, this means that the events are not independent.

So, we know that the probability of winning is 0.53

Now, given that they win, the probability of scoring 5 or more times will be q' such that:

0.53*q' = 0.43

q' = 0.811

This means that when they win, the probability of scoring more than 5 times is 0.81

Then the probability of scoring less than 5 times when they win is 1 minus the above probability:

P = 1 - 0.81 = 0.19

The probability of scoring fewer than 5 runs when they win is P = 0.19

The cost of the ice needed to make 50 snow cones is $54.50.

The first step is to determine the volume of the snow cone.

Volume of the snow cone =volume of a cone + volume of the hemisphere

Volume of the cone = 1/3πr²h

1/3 x 3.14 x 10.2 x (8.3/2)² = 183.87 cm³

Volume of the hemisphere = 2/3πr³

2/3 x 3.14 x (8.3 / 2)³ = 224.43 cm³

Total volume = 224.43 cm³ + 183.87 cm³ = 408.30 cm³

Volume of 50 snow cones =  408.30 cm³ x 50 = 20,414.82

Total grams of ice needed = density x volume

0.697 x 20,414.82 = 14,229.13 grams

Convert gram to 1kg

1kg = 1000g

= 14,229.13 grams  / 1000 = 14.23kg
