Check the picture below

if your calculator is in Degree mode, you'll get the angle in degrees, if in Radian mode, you'll get radians get taking the inverse sine, so you know

Answer:  The correct option is (A) 67.

Step-by-step explanation:  We are given to find the measurement of angle F to the nearest degree.

From the figure, we note that

Triangle FGH is aright-angled triangle with FH as the hypotenuse, where

FG = 5 units, GH = 12 units and FH = 13 units.

m∠F = ?

With respect to angle F, GH is the perpendicular and FG is the base.

From trigonometric ratios, we have

\sin m\angle F=\dfrac{perpendicular}{hypotenuse}\\\\\\ \Rightarrow \sin m\angle F=\dfrac{GH}{FH}\\\\\\\Rightarrow \sin m\angle F=\dfrac{12}{13}\\\\\\\Rightarrow \sin m\angle F=0.92307\\\\\Rightarrow m\angle F=sin^{-1}(0.92307)\\\\\Rightarrow m\angle F=67.37^\circ.

To the nearest degree, m∠F = 67°.

Thus, the measure of angle F is 67°.

Option (A) is CORRECT.

serg [7]

Answer:

0.288 < p < 0.338

Step-by-step explanation:

We have 2331 adults polled and 730 said they believe in UFOs.  We are to construct a 99% confidence interval for the population proportion.  We are told to round to 3 decimal places as needed.  

We need to find p-hat and q-hat

p-hat = 730/2331 = 0.313

q-hat = 1 - p-hat = 1 - 0.313 = 0.687

Since the sample size is greater than 30, we use a z-value for 99% confidence, which is 2.575

See attached photo for the construction of the confidence interval

I am confused about ii) help please
Jobisdone [24]

Step-by-step explanation:

i)=

m=2/3

x=-3

y = 5

now

y=mx+c

or, 5 = 2/3× -3 + c

or, 5 = -2+c

c =7

now,

y= mx + c

or, y = 2/3×x+7

or, y = 2x/3+7

or, 3y = 2x+21

so, 3y-2x=21

equation would be 3y-2x=21.

now

ii)=

if slope of 3y-2x=21 and 2x-3y = 0 are same, they are parallel.

2x-3y = 0

2x = 3y

lets suppose x is 9

now

2x=3y

2×9 = 3y

or, 18 = 3y

so, y = 6

one coordinate would be (9,6) now

lets again suppose x is 3

2x=3y

2×3 = 3y

or, 6 = 3y

so, y = 2

another coordinate is (3,2)

now lets find slope

x1=9,y1=6

x2=3,y2=2

slope = (y2-y1)/(x2-x1)

= (2-6)/(3-9)

= -4/-6

= 2/3

Since, slope of 3y-2x=21 and 2x-3y has same slope 2/3, they are parallel.

Write an inequality, in slope-intercept form, for the graph below. If necessary,
d1i1m1o1n [39]

Answer:not 100 % sure but I can write a slope intercept form equation, but not an inequality. I would need a picture of the graph to write an inequality.

First find slope: (y2 - y1)/(x2 - x1)   Slope is 3

Choose a point then use point slope form y - y1 = m(x - x1)      It is y - 1 = 3(x - 1)

Now simplify:

y - 1 = 3(x - 1)

y - 1 = 3x - 3

y = 3x - 2

y = 3x - 2
