Answer:
x _> 9 I dont have the symbol on my phone so I just put the greater than sign there
Step-by-step explanation:
1. Subtract 3 from both sides
5x > 48 - 3
2. simplofy 48 - 3 to 45
5x > 45
3. Divide both sides by 5
x > 45/5
4. Then simplify 45/5 to 9 which gives us the answer
And again I dont have the sign thats why I used the greater than sign
Answer:
x=21
Step-by-step explanation:
x-7=14
add 7 to both sides
x=21
Answer: 0.24 +/- 0.088 = (0.152, 0.328)
Step-by-step explanation:
The point estimate p is given by;
p= 24/ 100 = 0.24
Z value for 96% confidence interval is 2.05
The solution for the given confidence interval is derived using the equation
p +/- z√(pq/n)
Where p = 0.24 q= 1-p = 0.76, n=100 z= 2.05
= 0.24 +/- 2.05√(0.24×0.76/100)
= 0.24 +/- 2.05(0.0427)
=0.24 +/- 0.088
= ( 0.152, 0.328)
Ten and negative 2 will be in q1 and negative 3 and 8 will be in q2
Answer:
Scale factor, K = -1/4
Step-by-step explanation:
Dilation of any image changes its size and the shape remains same.
The scale factor is the ratio of dilated image to original image.
Dilation rule: (x, y) → (kx, ky), where k is the scale factor.
It means k = x₂/x₁ or y₂/y₁
K = -5/20 = -1/4 or K = -4/16 = -1/4.
<u>The negative value of scale factor (K) indicates dilations with 180 degree rotation of the dilated image.</u>
Hence the scale factor is K = -1/4.
