before conducting some experiments, a scientist mixes 1/2 gram of Substance A with 3/4 gram of Substance B. If the scientist use
horrorfan [7]

Mixing the two ingredients would be adding them together:

1/2 gram + 3/4 gram = 1 1/4 total grams


Divide the total grams by 1/8 to find the number of experiments they can do:

1 1/4 / 1/8 = 5/4 / 1/8 = 5/4 * 8/1 = 40/4 = 10


They can conduct 10 experiments.

A triangle has sides of LaTeX: 1\frac{1}{6}1 1 6 inches, LaTeX: 1\frac{1}{3}1 1 3 inches, and LaTeX: 1\frac{2}{3}1 2 3 inches. W
Nuetrik [128]

Answer:

4 1/6 inches

Step-by-step explanation:

A triangle has sides of LaTeX: 1\frac{1}{6}1 1 6 inches, LaTeX: 1\frac{1}{3}1 1 3 inches, and LaTeX: 1\frac{2}{3}1 2 3 inches. What is the perimeter of the triangle? Make sure your answer is in simplest form.

Perimeter of Triangle = Side a + Side b + Side c

Perimeter of the Triangle =

( 1 1/6 + 1 1/3 + 1 2/3) inches

Lowest common denominator = 6

= 1 + 1 + 1 +(1/6 + 1/3 + 2/3)

= 3 + (1 + 2 + 4/6)

= 3 + 7/6

= 3 + 1 1/6

= 4 1/6 inches

The number X of days in the summer months that a construction crew cannot work because of the weather has the probability distri
Ronch [10]

Answer:

a.)The probability of losing no more than ten days next summer is    

    0.65

b.) The probability that 8 - 12 days will be lost next summer  is 0.8

c.)  The probability there will be no days lost next summer is 0.

Step-by-step explanation:

The probability distribution for the number X of days in the summer that a construction crew cannot work because of the weather is given below:

x                    P(x)

6                   0.03

7                   0.08

8                   0.15

9                   0.2

10                  0.19

11                   0.16

12                   0.1

13                   0.07

14                   0.02

a.) To find the probability that no more than 10 days will lost next summer can be found by adding the values of probability of the days lost which are 10 days or less, that is to say we can write

 

p( x ≤ 10 )  = p(x=6) + p(x =7) + p(x=8) + p(x=9) + p(x=10)

                = 0.03     + 0.08    + 0.15     + 0.2     + 0.19

                = 0.65

b.) To find the probability that 8 to 12 days will be lost next summer will be given by taking into account and adding the probabilities starting form the probability when 8 days are lost to the probability when 12 days are lost

   p( 8 ≤ x ≤ 12)  = p(x=8) + p(x=9) + p(x=10) + p(x=11) + p(x=12)

                          = 0.15 +    0.2     + 0.19    +   0.16  + 0.1

                          = 0.8

c.) The probability that no days will be lost next summer will be given by

    = 1 - ( p(x=6) + p(x=7) +  p(x=8) + p(x=9) + p(10) + p(11) + p(12))

    = 1 -  1

    = 0  

   The probability that will be no days lost next summer is zero. We can conclude that there will be some days lost next summer.
