Answer:

a right angle

Step-by-step explanation:

The best and most correct answer among the choices provided by the question is the second choice "a right angle"The formula for finding the slope of a line on a coordinate plane is (y2 - y1) / (x2 - x1), where (x2, y2) and (x1, y1) represent two distinct points on the line. This is also known as "change in y over change in x" or "rise over run."I hope my answer has come to your help. God bless and have a nice day ahead!

Please help me find limit

Answer:

-13/11

Step-by-step explanation:

Straightforward evaluation of the expression at x=1 gives (1 -1)/(1 -1) = 0/0, an indeterminate form. So, L'Hopital's rule applies. The ratio of derivatives is ...

$\displaystyle\lim_{x\to 1}\dfrac{n}{d}=\dfrac{n'}{d'}=\left.\dfrac{\dfrac{4}{3\sqrt[3]{4x-3}}-\dfrac{7}{2\sqrt{7x-6}}}{\dfrac{5}{2\sqrt{5x-4}}-\dfrac{2}{3\sqrt[3]{2x-1}}}\right|_{x=1}=\dfrac{4/3-7/2}{5/2-2/3}=\dfrac{8-21}{15-4}\\\\=\boxed{-\dfrac{13}{11}}$

plz help doing test rn i need it

Answer:

$|answer| \\ 1)0=0 \\ 2)0=28$

3)The example equation becomes "x + 10 - 15x = 20," which is then "-14 x + 10 = 20." Subtract 10 from each side, divide by 14 and you have end up with x = -10/14, which simplifies to x = -5/7. Plug in the x value in to the first equation to find out the y value. y = 2 - 3(-5/7) becomes 2 + 15/7, which is 29/7.

Novay_Z [31]

The given figure can be drawn as,

From the figure,

$\tan \theta=\frac{opposite\text{ side}}{\text{adjacent side}}$

$\begin{gathered} \tan \theta=\frac{DE}{EC} \\ \tan \theta=\frac{1.5}{2.5} \\ \tan \theta=0.6 \end{gathered}$

Since angle of incidence will be equal to angle of reflection, $\begin{gathered} \text{tan}$ Therefore, the height of cactus is 6 m.

A public health department wants to determine the rate that parents of teen boys are choosing to vaccinate their sons for HPV wi

viktelen [127]

Answer:

The correct option is B

Step-by-step explanation:

From the question we are told that

The sample size is $n = 64$

The proportion that choose to vaccinate the teen boys is $\r p = 0.12$

considering the first statement

The 95% confidence interval is 12% ± the margin of error*standard deviation is false because

The 95% confidence interval is is %12 ± the margin of error

considering the second statement

The confidence interval should not be calculated due to the small sample size is true because from the central limit theorem

np = 64 * 0.12 = 7.68

and this value is less than 10 hence the confidence interval should not be calculated

considering the third statement

A 99% confidence interval will be smaller than the 90% confidence interval is false

This is because as the confidence level increase (for example from 90% to 99%) the margin of error increase which increases the confidence interval
