Hi there!

To find the unknown addend, we can just subtract:

1 - 2/6 = 4/6
4/6 = 2/3

Hope this helps!

2/6 + 2/3 = 1

To find this, you would replace the blank with a variable (x), and calculate.

2/6 simplified is 1/3

1 - 1/3 = 2/3

Hope this helped. ♡

What's the answer?????????????

Answer:

BD = 12 :)

Step-by-step explanation:

Alright, we'll need the Pythagorean theorem for this!

So, the length of AC is 10. That means the lengths of AD and DC are both half of that, which is 5 :)

DC = 5

We already know that BC = 13, so we can plug in these values into the pythagorean theorem for the right triangle BDC:

BD^2 + DC^2 = BC^2

BD^2 + 5^2 = 13^2

BD^2 + 25 = 169

BD^2 = 169 - 25 = 144

BD = √144 = 12 :)

Rewrite in simplest rational exponent form √x • 4√x. Show each step of your process.

Vikentia [17]

Step-by-step explanation:

$= \sqrt{x} .4 \sqrt{x}$

$= {x}^{ \frac{1}{2} } \times 4 {x}^{ \frac{1}{2} }$

$= 4 {x}^{ \frac{1}{2} + \frac{1}{2} }$

$= 4 {x}^{ \frac{2}{2} }$

$= 4 {x}^{1}$

$= 4x$

Listed below are time intervals (min) between eruptions of a geyser. Assume that the "recent" times are within the past few y

Shalnov [3]

Answer:

p value = 0.039

t = - 2.169

Step-by-step explanation:

Applying the null and alternate hypothesis

$H_{0} : U1 = U2$

$H_{\alpha } : U1 \neq U2$

using excel worksheet to calculate for ( t and p )

t = -2.169

p = 0.039

from the results obtained

The conclusion is affected by the significance level because : 0.1 < p > 0.01

so when the significance level is = 0.1 the Null hypothesis is rejected and we can say the mean time interval will change while

if the significance level = 0.01 the Null hypothesis is accepted and we can not say the mean time interval has changed because the p -value is greater than 0.01

attached is the excel solution
