) What is the distance between this pair of points? (-5, 2) and (-5, 6)

Leni [432]

Answer:

$d=4$

Step-by-step explanation:

Distance Formula: $d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Simply plug in the 2 coordinates into the distance formula to find distance d:

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

$d=\sqrt{(-5+5)^2+(4)^2}$

$d=\sqrt{(0)^2+16}$

$d=\sqrt{0+16}$

$d=\sqrt{16}$

$d=4$

frozen [14]

Answer:

(1) Please find attached the graph of the data

(2) 160.396 m

(3) The correlation that exist is a straight line correlation

Step-by-step explanation:

The given data are;

Distance, Time

(m), (s)

50, 6.1

100, 12

150, 18.3

200, 25.2

250, 31.7

(2)

Based on the linear regression formula, we have;

$b = \dfrac{N\sum XY - \left (\sum X \right )\left (\sum Y \right )}{N\sum X^{2} - \left (\sum X \right )^{2}}$

$b = \dfrac{5 \times 17215 - 93.3 \times 750}{5 \times 2156.03 -8704.89} = 7.758$

$a = \dfrac{\sum Y - b\sum X}{N}$

$a = \dfrac{750 - 7.7581 \times 93.3}{5}= 5.234$

The line is

y = 7.7581×x+5.234

When t = 20 s, we have

y = 7.7581*20+5.234 = 160.396 m

(3) The correlation that exist is a straight line correlation

I need solving 4.8 (x+4)=2.6

victus00 [196]

4.8 (x+4)=2.6
Use distributive property
4.8x + 19.2= 2.6
Subtract 19.2 from both sides
4.8x = -16.6
Divide 4.8 on both sides so that the only thing remaining on the left side is the variable x.
Final Answer: x = -3.458
