A circuit overloads at 1800 watts of electricity you plug in a toaster that uses 800 watts of electricity write and solve an ine

dangina [55]

Answer:

x ≤ 1000 W

Step-by-step explanation:

Since the circuit becomes overloaded when the load exceeds 1800W and the toaster uses 800 W.

Let the additional watts be x

Therefore;

800 + x ≤ 1800

x ≤ 1800 -800

x ≤ 1000 W

Alex is a member of the school track and field team. His times for running various distances are shown. Create a scatter plot fo

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
