Answer:

1. 17.59

2. 81.68

3. 8.99225

4. 12.00028

Step-by-step explanation:

for the first two you have to multiply the radii by 2 to find the diameter, then multiply your diameter by pi (3.14) to find the circumference

for the second two you have to work backwards so you have to divide the circumference by pi (3.14) which will give you the diameter, then you have to divide the diameter by 2 to get the radius.

Given PQ = 24

Verdich [7]

The shape PQRS is a parallelogram

The measure of angle QRS is 70 degrees
The measure of angle PQS is 53 degrees
The measure of angle RPS is 35 degrees
The measure of angle PSQ is 53 degrees

The given parameters are:

$\mathbf{\angle PQR = 106}$

$\mathbf{\angle QSR = 49}$

$\mathbf{\angle PRS = 35}$

(a) Find QRS

This is calculated as:

$\mathbf{\angle QRS = 2 \times \angle PRS }$

So, we have:

$\mathbf{\angle QRS = 2 \times 35}$

$\mathbf{\angle QRS = 70}$

Hence, the measure of angle QRS is 70 degrees

(b) Find PQS

This is calculated as:

$\mathbf{\angle PQS = \frac 12 \times \angle PQR }$

So, we have:

$\mathbf{\angle PQS = \frac 12 \times 106}$

$\mathbf{\angle PQS = 53}$

Hence, the measure of angle PQS is 53 degrees

(c) Find RPS

This is calculated as:

$\mathbf{\angle RPS = \angle PRQ }$

Where:

$\mathbf{\angle PRQ = \angle PRS = 35}$

So, we have:

$\mathbf{\angle RPS = 35}$

Hence, the measure of angle RPS is 35 degrees

(d) Find PSQ

This is calculated as:

$\mathbf{\angle PSQ =\frac 12 \times \angle PQR }$

Where:

$\mathbf{\angle PSQ =\frac 12 \times \angle 106}$

So, we have:

$\mathbf{\angle PSQ =53}$

Hence, the measure of angle PSQ is 53 degrees

I'm Sorry for all the work. I swear this is the last one! Please just help me in this last question.....

luda_lava [24]

Answer:

Step-by-step explanation:

y=mx+b where m=slope and b=y intercept

m=(y2-y1)/(x2-x1), we have points (0,0) and (4,12)

m=(12-0)/(4-0)=12/4=3

y=3x+b, using point (4,12) we can solve for b

12=3(4)+b

12=12+b

b=0 so the line is

y=3x

Answer:

Intervalo de confianza

= (0.294, 0.386)

Step-by-step explanation:

La fórmula para el intervalo de confianza para la proporción se da como

p ± z × √p (1 - p) / n

Donde p = x / n

De donde de la pregunta anterior

x = 136 personas

n = 400 personas

p = 136/400

p = 0.34

z = puntuación z del intervalo de confianza del 95% = 1.96

Por lo tanto,

Intervalo de confianza =

0.34 ± 1.96 × √0.34 (1 - 0.34) / 400

= 0.34 ± 1.96 × √0.34 × 0.66/400

= 0.34 ± 1.96 × √0.000561

= 0.34 ± 1.96 × 0.0236854386

= 0.34 ± 0.0464234596

Intervalo de confianza

= 0.34 - 0.0464234596

= 0.2935765404

= 0.34 + 0.0464234596

= 0.3864234596

Hence:Intervalo de confianza

= (0.294, 0.386)

Please help, system of equasions

arlik [135]

Answer:

$x = 4, y = 4$

Step-by-step explanation:

$x+y=8$

The total number of caps or shirts needed will be equal to the total amount of people in the system.

$6x+3y=36$

We can multiply the amount of caps and shirts by their price to get the total price needed.

$y=8-x\\6x+3(8-x)=36\\6x+24-3x=36\\3x=12\\x=4$

We can substitute one equation into another to solve for x.

Now we put our x value back into the other equation to get y

$4+y=8\\y=4$

Now we substitute both of our values into our second equation to verify that they are correct

$6(4)+3(4)=36$

So correct!
