Find the distance between the points (-3, 11) and (5,5).<br> O 10<br> 2/10<br> o 2.17

german

Answer: d = 10

Step-by-step explanation:

Step-by-step explanation:

The formula for calculating distance between two points is given by :

d = $\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}$

$x_{1}$ = -3

$x_{2}$ = 5

$y_{1}$ = 11

$y_{2}$ = 5

substituting the values , we have

d = $\sqrt{(5-(-3))^{2}+(5-11)^{2}}$

d = $\sqrt{(5+3)^{2}+(-6)^{2}}$

d = $\sqrt{(8)^{2}+(-6)^{2}}$

d = $\sqrt{64+36}$

d = $\sqrt{100}$

d = 10

A student believes that less than 50% of students at his college receive financial aid. A random sample of 120 students was take

marusya05 [52]

Answer:

p= 0.9995 and we can conclude that students receiving aid is more than 50% according to the sample results in 2% significance level.

Step-by-step explanation:

$H_{0}$ : less than or equal 50% of students at his college receive financial aid

$H_{a}$ : more than 50% of students receive financial aid.

According to the nul hypothesis we assume a normal distribution with proportion 50%.

z-score of sample proportion can be calculated using the formula:

z= $\frac{X-M}{\frac{s}{\sqrt{N} } }$ where

X is the sample proportion (0.65)
M is the null hypothesis proportion (0.5)
s is the standard deviation of the sample ( $\sqrt{0.5*(1-0.5)}$ )
N is the sample size (120)

then z= $\frac{0.65-0.50}{\frac{\sqrt{0.25}}{\sqrt{120} } }$ ≈ 3,29

thus p= 0.9995 and since p<0.02 (2%), we reject the null hypothesis.

Prove the identity secxcscx(tanx+cotx)=2+tan^2x+cot^2x

svetlana [45]

Hello,

$sec(x)= \dfrac{1}{cos(x)} \\

cosec(x)= \dfrac{1}{sin(x)} \\

sec(x)*cosec(x)*(tg(x)+cotg(x))=\dfrac{1}{cos(x)}* \dfrac{1}{sin(x)}*( \frac{sin(x)}{cos(x)} +\frac{cos(x)}{sin(x)})\\

= \dfrac{sin^2(x)+cos^2(x)}{sin^2x*cos^2x} \\

= \dfrac{1}{sin^2x*cos^2x} \\

$
==============================================================
$2+tg^2(x)+cotg^2(x)=2+ \dfrac{sin^2x}{cos^2x} + \dfrac{cos^2x}{sin^2x} \\

=2+ \dfrac{sin^4x+cos^4x}{sin^2x*cos^2x} \\

=\dfrac{2*sin^2x*cos^2x+sin^4x+cos^4x}{sin^2x*cos^2x} \\

= \dfrac{(sin^2x+cos^2x)^2}{sin^2x*cos^2x}} \\

= \dfrac{1}{sin^2x*cos^2x}}

The family leave home at 9 A.M. At that point, the car's odometer reads 31,247. They drive until 12:30 P.M., when they stop for

Tom [10]

Answer:

$\text{Speed} = 70 \text{ miles per hour}$

Step-by-step explanation:

The car shift is $31,492-31,247 = 245 \text{ miles}$

Time passed: $3.5 \text{ h}$

Once Speed is $\frac{\text{Distance}}{\text{Time}}$

$\text{Speed} =\frac{\text{245}}{\text{3.5}}$

$\text{Speed} = 70 \text{ miles per hour}$
