Rewrite each fraction with a denominator of 10 7/2 3/5

Vaselesa [24]

Answer:

$\frac{7}{2}=\frac{35}{10}$

$\frac{3}{5}=\frac{6}{10}$

Step-by-step explanation:

Given the fraction

$\frac{7}{2}$

Multiplying numerator and denominator by 5

$\frac{7}{2}\times \frac{5}{5}$

$=\frac{35}{10}$

Therefore,

$\frac{7}{2}=\frac{35}{10}$

Similarly,

Given the fraction

$\frac{3}{5}$

Multiplying numerator and denominator by 2

$\:\frac{3}{5}\times \:\frac{2}{2}$

$\frac{3}{5}\times \:\frac{2}{2}=\frac{6}{10}$

Therefore,

$\frac{3}{5}=\frac{6}{10}$

What the slope of a line

swat32

Answer:

The slope of a line is a number that measures its "steepness", usually denoted by the letter m. It is the change in y for a unit change in x along the line.

Hope it helps.

Which equation should be used to find the volume of the figure?

DaniilM [7]

Answer:

Given that

1

John can run 100 meters dash in 16 --------- seconds .

5

Savanna 's time is 19.8 seconds .

Here we have John time in mixed fraction and Savanna's time in decimal .

Converting mixed fraction into improper .

1 16 * 5 + 1 80 + 1 81

16 -------- = --------------------------- = -------------- = - -----------

5 5 5 5

Thus we got John time as 81 /5 seconds .

Converting Savanna's time in fraction , we get

19 8

---------- seconds .

10

We have two fractions with different denominator .

One is having denominator 5 and another is having denominator 10 .

We need to make the denominator same of both the fraction .

We need to make denominator 10 .

Multiply John fraction by 2 in both numerator and denominator by 2 to make denominator 10 .

81 * 2 162

---------- = ------------ seconds .

5 * 2 10

John is taking less time than Savanna . Thus John is faster .

Difference

198 162 36

------- - ------- = ------- seconds

10 10 10

Thus John is faster by (36/10 ) seconds = 3.6 seconds.

Step-by-step explanation:

Rabies is a viral disease of mammals transmitted through the bite of a rabid animal. The virus infects the central nervous syste

lisabon 2012 [21]

Answer:

(a) The value of x is 0.30.

(b) The probability that a reported case of rabies is not a raccoon is 0.45.

(c) The probability that a reported case of rabies is either a bat or a fox is 0.15.

Step-by-step explanation:

Denote the events as follows:

R = reported case of rabies is a raccoon

F = reported case of rabies is a fox

B = reported case of rabies is a bat

O = reported case of rabies is a some other animal.

The data provided is:

P (R) = 0.55

P (F) = 0.11

P (B) = 0.04

P (O) = x.

(a)

A property of a probability distribution is that the sum of all individual properties is 1.

That is, $\sum P(X)=1$

Compute the value of x as follows:

$\sum P(X)=1\\P(R)+P(F)+P(B)+P(O)=1\\0.55+0.11+0.04+x=1\\0.70+x=1\\x=1-0.70\\x=0.30$

Thus, the value of x is 0.30.

(b)

The probability of the complement of an event is the probability of its not happening.

$P(A^{c})=1-P(A)$

Compute the probability that a reported case of rabies is not a raccoon as follows:

$P(R^{c})=1-P(R)\\=1-0.55\\=0.45$

Thus, the probability that a reported case of rabies is not a raccoon is 0.45.

(c)

Compute the probability that a reported case of rabies is either a bat or a fox as follows:

$P(B\cup F)=P(B)+P(F)\\=0.11+0.04\\=0.15$

Thus, the probability that a reported case of rabies is either a bat or a fox is 0.15.
