What is b/3+1/8=19 I need help

Mathematics

yan [13]4 years ago

If you're solving for b, then you'll want to add the fractions first. this means you have to make a common denominator --> 8b/24 + 3/24 (24 is lcm) = 19
so (8b+3)/24 = 19... get the denominator out by multiplying 24 to both sides
so
8b+3=456
     -3    -3
8b=453
divide both sides by 8 to get b alone
b=56.625

Question:

In a neighbourhood pet show, each of the animals entered is equally likely to win. if there are 7 dogs, 6 cats, 3 birds, and 2 gerbils entered, what is the probability that a bird will win the top prize?

Answer:

Probability that a bird will win the top prize is 0.167

Step-by-step explanation:

Given:

The number of  dogs  = 7

The number of  cats = 6

The number of  birds  = 3

The number of gerbils = 2

To Find:

Probability that a bird will win the top prize = ?

Solution:

Let us first find the total number of  pets .

The Total number of pets = 7 + 6 + 3  + 2 =  18

Now the probability of  a bird will win the top prize is

=> \frac{\text {Number of birds}}{\text{ Total number of pets}}

=>\frac{3}{18}

=> \frac{1}{6}

=>0.167

Point C is located at (1, 2), and point D is located at (−4, −2). Find the x value for the point that is 1 over 4 the distance f
lutik1710 [3]

Answer:

Point C occurs on the line x = 1

Point D occurs on the line y = -2

The intersection of both lines occurs at the point E = (1,-2)

The difference between the x coordinates of points D and E is 1 + 1/4 units

The difference between the y coordinates of points C and E is 1 unit

Let point F be the point that is 1/4 the distance from point C to point D

To find the x-coordinate F subtract the difference between the x coordinate of points C and E from the x-coordinate of C:

1 - (1 + 1/4) = -1/4

To find the y-coordinate of F subtract the difference between the y-coordinates of D and E from the y-coordinate of C

2 - 1 = 1

The coordinates of point F are (-1/4, 1)

Therefore, the y value of the point that is 1/4th the

A study conducted on American families shows that 18% of these families have medical bills of more than $10,000. Find the probab
Svetllana [295]

Answer:

the probability is 0.6293

Step-by-step explanation:

The computation of the probability is shown below:

Given that

n = 5

P = 0.18

As it represents the  binomial distribution

P(X = x) =  ^NC_x× p^x × (1 - p) ^(n - x)

P(X > 1) = 1 - P(X < 1)

= 1 - P(X = 0)

= 1 - ( ^5C_0× (0.18) ^0 × (0.82) ^5)

= 1 - 0.3707

= 0.6293

hence, the probability is 0.6293
