What is the simplified form of this expression (-3x^2+4x)+(2x^2-x-11)

zlopas [31]

Answer:

SolutioN :

$\bf \: \star ( - 3x^{2} + 4x) + (2 {x}^{2} - x - 11)$

$\longrightarrow \bf \: - 3 {x}^{2} + 4x + 2 {x}^{2} - x - 11$

$\longrightarrow \bf \: - 3 {x}^{2} + 2 {x}^{2} + 4x - x - 11$

$\longrightarrow \boxed{\bf \: - {x}^{2} + 3x - 11}$

Five students visiting the student health center for a free dental examination during National Dental Hygiene Month were asked h

Andrews [41]

Answer:

[0.9 months, 32.69 months]

Step-by-step explanation:

The mean is

$\bf \bar x=\frac{5+17+12+21+29}{5}=16.8$

The standard deviation is

$\bf s=\sqrt{\frac{(5-16.8)^2+(17-16.8)^2+(12-16.8)^2+(21-16.8)^2+(29-16.8)^2}{5}}=8.1092$

Now, we have to find two values a and b such that the area under the Normal curve with mean 16.8 and standard deviation 8.1092 between a and b equals 95% = 0.95

Using a spreadsheet we find these values are

a = 0.906

b = 32.694

<h3>(See picture) </h3>

and our 95% confidence interval for the mean number of months elapsed since the last visit to a dentist for the population of students participating in the program rounded to two decimal places is

[0.9 months, 32.69 months]

WILL GIVE BRAINLIEST! What is the m∠ F? thanks for helping

natita [175]

X + x - 5 + 3x + 25 = 180
5x + 20 = 180
5x = 160
x = 32

m<F = x - 5
m<F = 32 - 5
m<F = 27
