What is the sum of 3/8 and 1/16

Answers

Answer 1

Answer: make the denominators the same before you add so,
$(6)/(16)$ + $(1)/(16)$ = $(7)/(16)$

Answer 2

Answer: $(3)/(8) = (6)/(18) (6)/(16) + (1)/(16) = (7)/(16)$

What does the line x= 2 look like?

Answers

X = 2 means for whatever y value you select the x value will be 2. So if you graph a couple of coordinates it becomes quickly evident that x = 2 is a vertical line that crosses the x axis at 2.

x = 2

This would show a vertical line crossing the x axis at 2.

Since y = 0, there is no y intercept, which means it does not cross the y axis.

A music festival charges $54.95 per ticket sold on the day of the event. A ticket purchases before the festival costs only $39.95. They were 20,000 tickets sold for a total of 925,000. How many tickets did they sell at the music festival? How many tickets do they sell before the music festival?

Answers

b=number of ticets sold before
a=number of tickets sold after

cost of a ticket=number of tickets times cost per ticket
beforecost=39.95b
aftercost=54.95a

total cost=925000
39.95b+54.95a=925000

total number tickets=20000
b+a=20000

we have

39.95b+54.95a=925000
b+a=20000
multiply second equation by -39.95 and add to first equatin
39.95b+54.95a=925000
-39.95b-39.95a=-799000 +
0b+15a=126000

15a=126000
divide bot sides by 15
a=8400

sub back
b+a=20000
b+8400=20000
minus 8400 both sides
b=11600

11,600 tickets sold before
8400 tickets sold after

Answers

we know that

sin 45=opposite side/hypotenuse
opposite side=7√2
hypotenuse=x

sin 45=7√2/x--------> x=7√2/sin 45

sin 45=√2/2
so
x=7√2/(√2/2)-----> x=(7√2*2)/√2-----> x=14

the answer is
the value of x is 14

The value of x in the figure would be 14. Option 3.

Trigonometry problem

To get x, we can use the following formula:

Sine 45 = opposite/hypotenuse

In this case:

opposite = 7√2

hypotenuse = x

Thus:

Sine 45 = 7√2/x

x = 7√2/sine 45

= 7√2/√2/2

= 7√2 x 2/√2

= 14

In other words, the value of x is 14.

Question

The times of all 15 year old who run a certain race are approximately normally distributed with a given mean Mu = 18 sec and standard deviation Sigma = 1. 2 sec. What percentage of the runners have times less than 14. 4 sec?.

Answer:

A. 0.15%

Step-by-step explanation:

The times of all 15 year old who run a certain race are approximately normally distributed with a given mean as 18 sec and standard deviation as 1.2 sec.

We know that,

X = raw score = 14.4

μ = mean = 18

σ = standard deviation = 1.2

Putting the values,
