Find the distance between (3,-3) and (2,7)

yarga [219]

Answer:

$\sqrt{101} = D$

Step-by-step explanation:

Method #1

We can draw a <em>right triangle</em> on the graph upon where the points are located and use the Pythagorean Theorem:

${a}^{2} + {b}^{2} = {c}^{2}$

${1}^{2} + {10}^{2} = {c}^{2}$

$1 + 100 = {c}^{2}$

$101 = {c}^{2}$

$\sqrt{101} = c$

* Whenever we talk about distance, we ONLY want the NON-NEGATIVE root.

_______________________________________________

Method #2

Or, we can use the Distance Formula:

$\sqrt{[-x_1 + x_2]^{2} + [-y_1 + y_2]^{2}} = D$

[2, 7] [3, −3]

$\sqrt{[-3 + 2]^{2} + [3 + 7]^{2}} = D$

$\sqrt{[-1]^{2} + 10^{2}} = D$

$\sqrt{1 + 100} = D$

$\sqrt{101} = D$

** You see? It does not matter which method you choose, as long as you are doing the work correctly.

Information on a packet of seeds claims that 93% of them will germinate. Of the 200 seeds that I planted, only 175 germinated. (

Anvisha [2.4K]

Answer:

We reject H₀

we accept Hₐ seeds in the packet would germinate smaller than 93%

Step-by-step explanation:

Test of proportions

One tail-test (left side)

93 % = 0.93

p₀ = 0,93

1.- Hypothesis

<h3>H₀ ⇒ null hypothesis p₀ = 0.93</h3><h3>Hₐ ⇒ Alternative hypothesis p = 0.875</h3><h3>2.-Confidence interval 95 %</h3><h3>α = 0,05 </h3><h3>and </h3><h3>z(c) = - 1.64</h3><h3>3.- Compute z(s)</h3><h3>z(s) = (p - p₀)/√(p₀*q₀)/n z(s) = (0.875-0.93)/√0.93*0.07)200</h3><h3>z(s) = - 0,055/ √0.0003255</h3><h3>z(s) = - 0.055/ 0.018</h3><h3>z(s) = - 3,06</h3><h3>4.-Compere z(c) and z(s)</h3><h3>z(s) < z(c) -3.06 < -1.64</h3><h3>z(s) is in rejection region, we reject H₀</h3>
