Answer: QRS and TRU

Step-by-step explanation:

A dilation of 1 + 1/2 means that the second image is (1 + 1/2) times the lenght of the first one.

for this, you can chek with one of the sides of the triangles:

with the triangles QRS and TRU we have that the line RS has a lenght of 2 units, then the lenght of the RU must be 1 and 1/2 times that lenght:

RU = (1 + 1/2)*2 = 2 + 1 = 3 units

and we can see in the grap that the segment RU has a lenght of 3 units, so this is a dilation with a scale factor of 1 + 1/2

For the other 3 options we can see that in the top left one bot triangles are equal, and in the bottom two the dilation is witha scale factor of 2.

Add using the number line. 7+(−10) Drag and drop the word SUM to the correct value on the number line.
Amiraneli [1.4K]

Steps of adding 7+(-10) using number line are as following:


1) Draw a number line by ranging from -10 to +10.

2) Point out 7 on the number line.

3) Because -10 is added to 7 on the number line,  please move 10 numbers left to 7 on the number line. We always go left in addition of a negative number on the number line.

4) The number we reach -3 on left side would be our final sum.

5) From the number we can clearly see that moving 10 number on left to 7, we get -3.

Note: We are moving left because of negative sign in front of 10.

5/6v+10=5 what is the answer
yulyashka [42]

Answer:

x= -3/2

Step-by-step explanation:

You would multiply both sides by 6x+10 and then that would give you 5-5)6x+10) and you would divide both sides by 5. This would give you 1=6x+10, you would then try to isolate the 6x giving you -6x=10-1  or -6x=9 and you would see if the solutions are in the defined ranges so x=-5/3 is NOT in the defined range but x=-3/2 is.

The owner of a local nightclub has recently surveyed a random sample of n = 250 customers of the club. She would now like to det
Maru [420]

Answer:

0.077994

Step-by-step explanation:

Given that the owner of a local nightclub has recently surveyed a random sample of n = 250 customers of the club.

H_0: Mean = 30\\H_a: Mean >30

(Right tailed test)

Sample size = n=250

Sample mean = 30.45

Mean difference =30.45-30=0.45\\

Sample std dev s = 5

Sample std error = \frac{5}{\sqrt{n} } =\frac{5}{\sqrt{250} } \\=0.3163

Test statistic = Mean diff/std error = =\frac{0.45}{0.3163} =1.423

Since population std deviation is not know we use t test

p value = 0.077994
