Answer:

X = 18

y = 9

Step-by-step explanation:

Basically the 2 diagnols bisect each other making them congruent. so that makes

x-3 = 15 and y + 3 = 12

simplify and

the. you simplify and get x = 18 and y =9

Answer:

read the question and you will find the like the question and just find it out The weather report says the temperature is 20°c and will drop 5°c per hour for the next 6 hours.

Temperature drops by 5°c per hour

So we find the temperature after 6 hours

In 1 hour temperature drops= 5°c

So in 6 hours = 6* 5 = 30°c

In 6 hours , temperature drops by 30°c

the actual temperature is 20°c. after 6 hours the temperature becomes

20°c - 30°c= -10°c

So, after 6 hours the temperature will be -10°c

Daryl plans to be gone for at least 6 hours. so its 6 hours or more than 6 hours

In 6 hours or more than 6 hours , the temperature will drop less than -10°c

Hey!

To solve this equation, we'd first have to apply the distributing rule to this equation.

Original Equation :
$( 3a - 2 )^{2}$

New Equation {Changed by Applying the Distribution Rule} :
$( 3a )^{2} - 2$ · 3a · 2 + $2 ^{2}$

And now we simplify.

Old Equation :
$( 3a ) ^{2} -2$ · 3a · 2 + $2 ^{2}$

New Equation {Old Equation Simplified} :
$9a ^{2}$ - 12a + 4

So, the equation $(3a - 2) ^{2}$ simplified is $9a ^{2}$ - 12a + 4.

Hope this helps!

The z or t score to be used is (0.422,0.978)

How to find the critical value ?

Critical probability (p*) = 1 - (Alpha / 2), where Alpha is equal to 1 - (the confidence level / 100), is the unit statisticians use to determine the margin of error within a set of data in statistics.

The critical value for α = 0.13 is $z_{c} = \frac{z_{1} - \alpha }{2}$

The corresponding confidence interval is computed as shown below

$CI = (X1_{1} - X_{2}- z_{c} \sqrt{\frac{a_{1}^{2}}{n_{1} } + \frac{a_{2}^{2}}{n_{2} }} , X1_{1} - X_{2}+z_{c} \sqrt{\frac{a_{1}^{2}}{n_{1} } + \frac{a_{2}^{2}}{n_{2} }} )$
