Answer:

b.Distance between two ships=742.80 miles

Step-by-step explanation:

We are given that  two ships leave a harbor together ,travelling on course that have an angle of 135 degrees between them .

Distance travel by one ship=402 miles

Distance travel by second ship=402 miles

Angle between them =135 degrees

Distance between two ships =\sqrt{(402)^2+(402)^2-2(402)^2 cos 135}

Distance between two ships=402\sqrt{1+1+2 cos (90+45)}

Distance between two ships=402\sqrt{2+2sin45}

Distance between two ships=402\sqrt{2+\sqrt2}

Distance between two ships=742.799=742.80 miles

Distance between two ships=742.80 miles

Hence, option b is true.

HURRY PLEASE I WILL GIVE BRAINLIEST AND LOTS OF POINTS
Mrac [35]

Answer:

m =  \dfrac{3}{4}

Step-by-step explanation:

We would like to find the <u>s</u><u>l</u><u>o</u><u>p</u><u>e</u><u> </u> of the line of the given equation .

\longrightarrow y =\dfrac{3}{4}x -1

We know that <u>s</u><u>l</u><u>o</u><u>p</u><u>e</u><u> </u><u>i</u><u>n</u><u>t</u><u>e</u><u>r</u><u>c</u><u>e</u><u>p</u><u>t</u><u> </u><u>f</u><u>o</u><u>r</u><u>m</u><u> </u> of the line is given by ,

\longrightarrow y = mx + c

where ,

  • m is the slope
  • c is y intercept

Now we can compare the given equation with the slope intercept form to find the slope . You will see that 3/4 is present at the place of m .Therefore ,

\longrightarrow \underline{\underline{m=\dfrac{3}{4}}}

Hence <u>o</u><u>p</u><u>t</u><u>i</u><u>o</u><u>n</u><u> </u><u>C</u><u> </u> is correct choice .

The mean work week for engineers in start-up companies is claimed to be about 64 hours with a standard deviation of 8 hours. Kar
blondinia [14]

Answer:

1.) mean

2.) H0 : μ = 64

3.) 0.0028

4) Yes

Step-by-step explanation:

Null hypothesis ; H0 : μ = 64

Alternative hypothesis ; H1 : μ < 64

From the data Given :

70; 45; 55; 60; 65; 55; 55; 60; 50; 55

Using calculator :

Xbar = 57

Sample size, n = 10

Standard deviation, s = 7.14

Test statistic :

(xbar - μ) ÷ s/sqrt(n)

(57 - 64) ÷ 8 / sqrt(10)

Test statistic = - 2.77

Pvalue = (Z < - 2.77) = 0.0028 ( Z probability calculator)

α = 10% = 0.1

Reject H0 ; if P < α

Here,

P < α ; Hence, we reject the null
