Answer:

f(2) = 0 and g(–2) = 0

Step-by-step explanation:

When I am looking at the graph I notice that I see f(0)=4 and f(2) = 0.

When I look at the graph again I notice that I see g(0)=4 and g(-2)=0.

Now we can say that f(2) = g(-2) and f(0) = g(0)

f(2) = g(-2) = 0

f(0) = g(0) = 4

Hope This Helps :)

A farmer uses a lot of fertilizer to grow his crops. The farmer's manager thinks fertilizer products from distributor A contain

noname [10]

Answer:

$Z_{H0}$ = 1.56

Step-by-step explanation:

Hello!

You have two independent samples of fertilizers from distributor A and B, and need to test if the average content of nitrogen from fertilizer distributed by A is greater than the average content of nitrogen from fertilizer distributed by B.

Sample 1

X₁: Content of nitrogen of a fertilizer batch distributed by A

n₁= 4 batches

Sample mean X₁[bar]= 23pound/batch

σ₁= 4 poundes/batch

Sample 2

X₂: Content of nitrogen of a fertilizer batch distributed by B

n₂= 4 batches

Sample mean X₂[bar]= 18pound/batch

σ₂= 5 pounds/batch

Both variables have a normal distribution. Now since you have the information on the variables distribution and the values of the population standard deviations, you could use a pooled Z-test.

Your hypothesis are:

H₀: μ₁ ≤ μ₂

H₁: μ₁ > μ₂

The statistic to use is:

Z= <u> X₁[bar] - X₂[bar] - (μ₁ - μ₂) </u>~N(0;1)

√(δ²₁/n₁ + δ²₂/n₂)

$Z_{H0}$ =<u> </u>(<u>23 - 18) - 0 </u> = 1.56

√(16/4 + 25/4)

I hope this helps!

What Is The Recursive Rule For The Sequence? 1.2, 0.4, -0.4, – 1.2, -2,

nevsk [136]

<h3>Answer:</h3>

$\boxed{\bold{a_n = a_{n-1} -0.8}}$

<h3>Explanation:</h3>

<u>Sequence</u>: 1.2, 0.4, -0.4, – 1.2, -2,...

See that with every next term, the integers are decreasing by 0.8

So, common difference (d) = -0.8

<u>recursive formula</u> : $\sf a_n = a_{n-1} +d$

$\bold a_1 = 1.2,$ $\sf a_n = a_{n-1} + (-0.8)$

Factor the expression to find the zeros

Leno4ka [110]

Answer:

k = (1 , 4)

Step-by-step explanation:

here's your solution

==> k^2 - 5k + 4. [ is expression ]

==> by using middle term split

==> k^2 - 4k - k + 4

==> taking common from each

==> k(k - 4) - 1 (k - 4)

==> (k - 1) , (k - 4).

==> k - 1 = 0

==> k = 1

==> k - 4 = 0

==> k = 4

hence , k = (1 , 4)

hope it helps
