X = 2 cm

You need to use the Pythagorean theorem starting with the triangle on the far left and progressively moving to the right. (Comment if you want further explanation)

Answer:

2 cm

Step-by-step explanation:

First you use Pythagorean theorem in solving the triangle closest to the bottom. You would get the square root of two. Then you use Pythagorean theorem again on the second triangle and receive the answer of the square root of three you do the Pythagorean theorem again and receive the answer of the square root of four. Simplify that and get 2 cm.

Graph the line passing through the given point and having the indicated slope. through (3​, ​negative 2​) with slope minus−three
Alex17521 [72]

Answer:

See the attachment

Step-by-step explanation:

A slope of -3/5 means the line drops 3 units for each 5 units it goes to the right. Then you can find another point on the line by going 5 uints to the left (to x=-2) and 3 units up (to y=1).

Plot the given point and the one just computed and draw the line through them.

Answer:

The 95% confidence interval for the difference between the Route B and Route A commuting times is -3.771808 to 1.771808

Step-by-step explanation:

Here we have the confidence interval is given by the following equation;

\left (\bar{x}_1-\bar{x}_{2}  \right ) - z_{c}\sqrt{\frac{\sigma _{1}^{2}}{n_{1}}-\frac{\sigma _{2}^{2}}{n_{2}}}< \mu _{1}-\mu _{2}< \left (\bar{x}_1-\bar{x}_{2}  \right ) + z_{c}\sqrt{\frac{\sigma _{1}^{2}}{n_{1}}-\frac{\sigma _{2}^{2}}{n_{2}}}

\bar x_1 = 49 Minutes

σ₁ = 2 Minutes

\bar x_2 = 50 Minutes

σ₂ = 4 Minutes

n₁ = n₂ = 10 days

α = 0.05

At 95%, from the z score table , z_c = \pm1.959964 ≈ ± 1.96

Plugging in the values Solving we get

Δμ Min = -3.771808 and Δμ Max = 1.771808.
