The point Al-2, 3) is translated using T: (x,y) → (x+4, y+2).

Mathematics
1 answer:
almond37 [142]3 years ago

Answer:

The distance between A and A' is:

distance=\sqrt{20}

Step-by-step explanation:

Notice that point A' after the given translation becomes: (-2+4, 3+2) = (2, 5),

So one can calculate the distance between A (-2, 3) and A' (2, 5) using the distance formula:

distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\distance=\sqrt{(2-(-2))^2+(5-3)^2} \\distance=\sqrt{(4))^2+(2)^2} \\distance=\sqrt{(16+4} \\distance=\sqrt{20}

Consider Figure A and Figure B on the coordinates grid.
r-ruslan [8.4K]

Answer:

The answer is the first answer choice. (Reflect figure A in the y axis, followed by a 90 degree clockwise rotation about the origin)

Step-by-step explanation:

By reflecting over the y axis allows the shape to only have to move 90 degrees clockwise around the origin which is (0,0).

A rain gauge is accurate within 0.5 mm of the true rain height. One Sunday
tamaranim1 [39]

Answer: 59.5 ≤ r ≤ 60.5

Step-by-step explanation:

Given that :

Accuracy range = ±0.5 of true value

True height of rain (r) = 60mm

Absolute value equation to find the least and greatest height if rain possible ;

|r| = 0.5

To remove the absolute value sign ;

|r| ± 0.5

r = 60mm

60 - 0.5 ≤ r ≤ 60 + 0.5

59.5mm ≤ r ≤ 60.5mm

Hence,

Greatest height possible = 60.5mm

Least height possible = 59.5 mm

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
katen-ka-za [31]

Answer:

Option 2. \text{Reject}~ H_0~ \text{if}~ t > 2.3263

Step-by-step explanation:

We are given the following in the question:  

Population mean, μ = 30

Sample size, n = 250

Alpha, α = 0.01

First, we design the null and the alternate hypothesis

H_{0}: \mu = 30\\H_A: \mu > 30

We use Right-tailed t test to perform this hypothesis.

Formula:

t_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{\sigma}{\sqrt{n}} }

Now, t_{critical} \text{ at 0.01 level of significance, 249 degree of freedom } = 2.3263

Decision rule:

For a right ailed t-test,

t_{stat} > t_{critical}, we reject the null hypothesis as it lies in the rejection area.

t_{stat} < t_{critical}, we fail to reject the null hypothesis as it lies in the acceptance area and accept the null hypothesis.

Thus,

Option 2. \text{Reject}~ H_0~ \text{if}~ t > 2.3263
