To divide a fraction, you turn the numerator and denominator around, and multiply by the number you originally would divide it by. so you go 3/1 times by 5. so it is 15/1 so 15.

One angle of a right angled triangle is 63degree .find the other angle in grades

dexar [7]

Answer:

27°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

let the third angle be x , then

x + 90° + 63° = 180°

x + 153° = 180° ( subtract 153° from both sides )

x = 27°

Mark's school is selling tickets to the annual dance competition. On the first day of ticket sales the school sold 4 senior tick

erica [24]

The cost of each senior ticket is $ 5 and cost of each child ticket is $ 12

Solution:

Let "a" be the price of each senior ticket

Let "b" be the price of each child ticket

On the first day of ticket sales the school sold 4 senior tickets and 4 child tickets for a to total of 68

Thus a equation is framed as:

4 senior tickets x price of each senior ticket + 4 child tickets x price of each child ticket = 68

$4 \times a + 4 \times b = 68$

4a + 4b = 68 ---------- eqn 1

The school took in 120 on the second day by selling 12 senior tickets and 5 child tickets

Similarly, we frame a equation as:

$12 \times a + 5 \times b = 120$

12a + 5b = 120 ---------- eqn 2

Let us solve eqn 1 and eqn 2

Multiply eqn 1 by 3

12a + 12b = 204 -------- eqn 3

Subtract eqn 2 from eqn 3

12a + 12b = 204

12a + 5b = 120

( - ) --------------

7b = 84

b = 12

Substitute b = 12 in eqn 1

4a + 4(12) = 68

4a + 48 = 68

4a = 20

a = 5

Thus cost of each senior ticket is $ 5 and cost of each child ticket is $ 12

A survey of 250 homeless persons showed that 14 were veterans. Find a point estimate for the population proportion of homeless p

snow_lady [41]

Answer:

$\hat p =\frac{14}{250}= 0.056$

And for this case that represent the 5.6% of the homeless persons who are veterans

Step-by-step explanation:

We know that in a survey of 250 homeless persons 14 were veterans. We can find the estimated proportion of homeless persons who are veterans with the following formula:

$\hat p =\frac{X}{n}$

The last one is an unbiased estimator of the true population proportion p

And replacing the info given we got:

$\hat p =\frac{14}{250}= 0.056$

And for this case that represent the 5.6% of the homeless persons who are veterans
