Someone pls help me :c tysm if u do :))

Answer:

47 mph

Step-by-step explanation:

1 day = 24 hours, so 2 days = 48 hours.

2274/48 (2274 miles per 48 hours, simplify!) This equals 47.375. Round it down to 47 mph.

This is assuming the car took no breaks.

Hope this helps!

Queremos encontrar diferentes cosas en un experimento dado. Daremos una breve explicación para cada respuesta.

a) La población es el grupo de gente que se estudia, en este caso la medicina es para diabeticos, por lo que la población en este caso sería toda la gente que padece dicha enfermedad.

b) La muestra se refiere a la parte de la población que participa en el experimento, en este caso son 10,000 personas con diabetes.

c) El parametro de interes, es decir, lo que le interesa estudiar a los cientificos, será la efectividad del medicamento que estan desarrollando.

d) Sí, se conoce el valor del parametro, se sabe que en 90% de los casos es efectivo, escribiendo esto de forma decimal, podemos decir que el medicamento es efectivo con una probabilidad de 0.9.

Answer:

c. 2/3

Step-by-step explanation:

Since the line is going up to the right it is a positive slope. Therefore it can't be a or d.

The slope is 2/3 because to connect the dots you have to go up 2 and to the right 3.

Answer:

1/3

Step-by-step explanation:

because 1/3 is 0.333333

This is an exponential growth function.

If we look at the number that is raised to the power of x, it is greater than 1. Though there is a fraction within this equation, it is not affected by the exponential.

Rates are ratios that are renamed so that one of the numbers is 1. It is usually the denominator of the original ratio.

Answer:

132.50

Step-by-step explanation:

3/5b = 79.50

b = (79.50) / (3/5)

b = 79.50 * 5/3

b = 397.50/3

b = 132.50

132.50 is the total bill

Answer:

Simple springs obey Hooke's Law. Hooke's Law states that the force on a spring is proportional to it's displacement from it's resting length:

F = -k*x

Where F is the force, x is how far the string is stretched or compressed, and k is a proportionality constant called the spring constant. The negative sign is because the spring resists stretching.

In this case, we can solve for k using the first case:

(100N) = -k * (5cm)

k = ???

And plug that answer in to find x in the second case:

(360N) = -k * x

    This is a "Hooke's Law" problem: the restoring force required to compress or stretch a spring is proportional to the distance the spring is deformed.  You can figure solve it by setting up a proportion equation and then using the algebraic tool of cross multiplication to solve for the unkown "stretch".

1) set up the proportion equation

100  =  360

5           x

2) cross multiply to get a linear equation

100x = 5*360

3) solve for x

 100x = 1800

       x = 18

Answer:

The law: F=kx

Therefore,

180N = k * 5cm

k = 180÷5= 36N per cm

Using the known constant with the law,

270=36*x

x= 270 ÷ 36 = 7.5cm

Answer:

the value of x= 5

Step-by-step explanation:

hey there!

given;

∠P=90°( right angle)

now;

∠p=19x-5

90°+5°=19x

95/19=x

x=5

hope it helps!

Answer:

Step-by-step explanation:

Hi there!

∠SRQ = 162°

∠STR = 130°

∠RST = ?

Now;

∠SRQ = ∠RST+∠STR   [external angle is equal to the sum of opposite interior angles of triangle]

∠RST = ∠SRQ-∠STR

∠RST = 162°-130°

Therefore, the measure of ∠RST is 32°.

Answer:

14.9 min

Step-by-step explanation:

r=rate

r25=5*7

r25=35

r=35/25

r=1.4

substitution

r160=t*15

t=time

r=1.4

1.4*160=t*15

224=t*15/15

224/15=t

14.9 min

you do 4320÷ 9= 108 and that's your answer right there

Answer:

y = -4/3x -9

Step-by-step explanation:

Slope intercept form is

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

8x+6y = -54

Subtract 8x from each side

8x+6y-8x = -8x-54

6y = -8x-54

Divide each side by 6

6y/6 = -8x/6 -54/6

y = -4/3x -9

Answer:

y = -4/3x - 9

Step-by-step explanation:

Putting this into 'y=mx+c' form:

i) Firstly, make it only y on the LHS:

6y = -8x-54

ii) Secondly, making the 'y' have a co-efficient of 1. This can be done by dividing both sides by 6:

6y/6 = -8x/6 - 54/6

y = -4/3x - 9

Hence,

y = -4/3x - 9
