You can use models to estimate percent questions by estimating the locations of 50%, 75%, 40%, 6%, and 65% on the model..

angle 1 and angle 2 form a linear pair. If measure angle 1 =18x-1 and measure angle 2=23x+17, find measure angle 2.

Hey there!
Here's your answer: m<2=114.52 degrees
Here's how I got it: we know that a linear pair of angles is supplementary, aka the sum of the angles is 180 degrees.
you would add 18x-1 and 23x+7 together to equal 180 and solve for x.
then, you would substitute x for 4.24 (rounded) into 23x+17
23(4.24)+17=114.52
Hope this helps!

Step-by-step explanation:

Margin of error = critical value × standard error

The standard error is:

s = σ / √n

s = 7.4 / √664

s = 0.287

The population is normally distributed, so the critical value can be found from a z-score table.

For 90% confidence, z = 1.645.

For 95% confidence, z = 1.960.

For 99% confidence, z = 2.576.

The margins of error are:

90%: 1.645 × 0.287 = 0.4724

95%: 1.960 × 0.287 = 0.5629

99%: 2.576 × 0.287 = 0.7398

The mean is 26.6, so the confidence intervals are:

90%: (26.6 − 0.47, 26.6 + 0.47) = (26.13, 27.07)

95%: (26.6 − 0.56, 26.6 + 0.56) = (26.04, 27.16)

99%: (26.6 − 0.74, 26.6 + 0.74) = (25.86, 27.34)

Answer:

The third option is correct.

The domain of the function is given by

$Domain = 0 \leq t \leq 40$

The range of the function is given by

$Range = 0 \leq V(t) \leq 200$

Step-by-step explanation:

Sara bought a cell phone for $200 and its value has decreased at rate of $5 per month.

V(t) is the value of the phone and t is the number of months.

The domain of the function is the possible values of the number of months t.

The domain of the function is given by

$Domain = 0 \leq t \leq 40$

The range of the function is the values of V(t) that we get after substituting the possible values of the number of months t.

The range of the function is given by

$Range = 0 \leq V(t) \leq 200$

When the number of months is t = 0 then the value of the function is maximum V(t) = 200

When the number of months is t = 40 then the value of the function is minimum V(t) = 0

Therefore, the third option is correct.
