21 = -5x + 11

10 = -5x

n = -2

Answer:

PR = 16

SR = 12

Step-by-step explanation:

6/8 = (x-3)/(x+1)

8x-24 = 6x+6

simplify

2x = 30

x = 15

PR = 15 + 1 = 16

SR = 15 - 3 = 12

Ok I dont know how to do this im so sorry

Answer:

=127.23

Step-by-step explanation:

we can start of by finding the area of a CIRCLE

18/2=9

9=radius

area of circle= pi*r squared

9 squared=81*pi=254.4690

Now we can half the area of the circle to find out the area of the semi circle as a semi circle is just half a circle therefore half the area of a circle

254.469/2=127.2345

127.2345=127.23

=127.23

Answer:

B: 9

Step-by-step explanation:

First plug in the numbers to the equation

[tex]\frac{1}{4} (c^{3} + d^{2})[/tex]

[tex]\frac{1}{4} (-4^{3} + 10^{2})[/tex]

Then use PEMDAS to solve

[tex]\frac{1}{4} (-4^{3} + 10^{2})[/tex]

Answer:

a)

Sample mean p = 25% = 0.25

standard deviation σ = 0.025

b)

YES, it okay to use normal calculations for this problem since the sample size is 300, hence np>10 and nq>10

so the conditions satisfied for normal approximation/calculations

c) the probability that at least 26% of the sample is killed is 0.6554

Step-by-step explanation:

Given the data in the question;

Suppose that one such chemical would kill 25% of elm trees. The power company tests the chemical on 300 elms

sample size n = 300

a) What are the mean and standard deviation of the proportion of trees that are killed?

Sample mean p = 25% = 0.25

standard deviation σ = √( pq / n ) = √( (0.25 × (1 - 0.25)) / 300 )

σ = √( (0.25 × 0.75) / 300 )

σ = √( 0.1875 / 300 )

σ = √0.000625

σ = 0.025

standard deviation σ = 0.025

b) Is it okay to use normal calculations for this problem?

YES, it okay to use normal calculations for this problem since the sample size is 300, hence np>10 and nq>10

so the conditions satisfied for normal approximation/calculations

c) the probability that at least 26% of the sample is killed

Now we are to find

P( P < 0.26 )

since its a normal approximation, we can convert p to z

so

P( P < 0.26 ) =  P( Z < ( x-p / σ   )

P( P < 0.26 ) = P( Z < ( 0.26-0.25 / 0.025 )

= P( Z < (0.01 / 0.025) )

= P( Z < 0.4 )

form z score table; P( Z < 0.4 ) = 0.6554

so

P( P < 0.26 ) = 0.6554

the probability that at least 26% of the sample is killed is 0.6554

x=6

Step-by-step explanation:

Answer:

y = -3/2x + 7

Step-by-step explanation:

First, let's identify what slope-intercept form is: y = mx + b

We have:

3x + 2y = 14

Right away, we can see that we need to 1) move x to the right side of the equation and 2) simplify y.

1) To move x to the right side of the equation, subtract 3x from both sides.

2y = -3x + 14

2) To simplify y, divide both sides by 2. When dividing the right side by 2, you need to evaluate each component (3x and 14, not just one)

y = -3/2x + 7

This is your equation in slope-intercept form.

Hope this helps!

Answer: pretty sure

Step-by-step explanation:

Volume of a sphere:

V = 4/3 π r ³

Differentiate V with respect to time t :

dV/dt = 4π r ² dr/dt

Surface area of a sphere:

A = 4π r ²

Differentiate A with respect to t :

dA/dt = 8π r dr/dt

You're given that the volume is increasing at a constant rate, dV/dt = 10 cm³/s, so

10 cm³/s = 4π r ² dr/dt

Solve for dr/dt (the rate of change of the sphere's radius):

dr/dt = 5/(2π r ²) cm³/s

Substitute this into the equation for dA/dt :

dA/dt = 8π r (5/(2π r ²) cm³/s)

dA/dt = 20/r cm³/s

At the moment the radius is r = 5 cm, the surface area is increasing at a rate of

dA/dt = 20/(5 cm) cm³/s = 4 cm²/s

When the surface area is increasing at a rate of dA/dt = 2 cm²/s, the radius r is such that

2 cm²/s = 20/r cm³/s

which happens when the radius is

r = 20/2 (cm³/s) / (cm²/s) = 10 cm

Answer:

1 L of petrol is used to travel 9 km.

Step-by-step explanation:

You can find the answers through the ratio method

20 L : 180 km

1 L : x
