Hii please answer only if you know how its timed!! I REALLY NEED TO PASS

Can somebody help me on 23 and 24, it’s geometry

Question 23:

x = 4

DE = 44

Question 24:

x = 25

SE = 28

Step-by-step explanation:

As RS is the perpendicular bisector of DE, it will divide DE in two equal parts DS and SE

<u>Question number 23:</u>

Given

DS = 3x+10

SE = 6x-2

As the two segments are equal:

$DS = SE\\3x+10 = 6x-2$

Subtracting 10 from both sides

$3x+10-10 = 6x-2-10\\3x = 6x-12$

subtracting 6x from both sides

$3x -6x = 6x-6x-12\\-3x = -12$

Dividing both sides by -3

$\frac{-3x}{-3} = \frac{-12}{-3}\\x = 4$

Now

$DS = 3x+10\\= 3(4)+10\\= 12+10\\=22$

And

$SE = 6x-2\\= 6(4)-2\\= 24 - 2\\=22\\DE = DS+SE\\= 22+22\\=44$

<u>Question No 24:</u>

Given

DS = x+3

DE = 56

We know that:

$DS = \frac{1}{2}DE\\x+3 = \frac{56}{2}\\x + 3 = 28\\x = 28-3\\x = 25$

So

DS = $25+3 = 28$

As DS is 28, SE will also be 28

Hence,

Question 23:

x = 4

DE = 44

Question 24:

x = 25

SE = 28

A man who moves to a new city sees that there are two routes he could take to work. A neighbor who has lived there a long time t

sergiy2304 [10]

Answer:

0.3 to 2.3 min

Step-by-step explanation:

n1=n2=10

x1=48

x2=49

s1=4

s2=1

Determine the deegres of freedom.

$\delta=\frac{(\frac{s_1^2}{n_1}+\frac{s_2^2}{n_2})^2}{\frac{(\frac{s_1^2}{n1})^2}{n_1-1}+\frac{(\frac{s_1^2}{n1})^2}{n_2-1}}=10.14$

t=2.037 (student's appendix)

$E=t\sgrt(\frac{s_1^2}{n_1}+\frac{s^2_2}{n_2})=1.3$

$(x_1-x_2)-E=(48-49)-1.3=-2.3$

$(x_1-x_2)+E=(48-49)+1.3=0.3$

We are 95% confident that average commuting time for rute A is between 0.3 and 2.3 min shorter than for rute B.

Stels [109]

The bear beats its heart 50/6 times a minute during deep hibernation.

Thats 12 times a minute

45minutes x 12 times a minute

45x12 = 540
