Ajoba and Prav drive to work. Ajoba drives 45 miles in 2.5 hours. Prav drives 74 km in 1 hour 15 minutes. Work out the differenc

amm1812

Answer:

Ajoba: 28.8km/h

Prav: 59.2km/h

The difference in speed is: 59.2-28.8=30.4km/h

Step-by-step explanation:

Ajoba:

d=45mi Convert to km // $45mi(\frac{1.6km}{1mi} )=72km$

t=2.5h

v=? 28.8km/h

Prav:

d=74km

t=1h15m or 1.25h

v=? 59.2km/h

$Formula: d=v*t$

Solve for v;

$v=\frac{d}{t}$

$v=\frac{72km}{2.5h} \\v=28.8km/h$

--------------------------------------------

$v=\frac{d}{t}$

$v=\frac{74km}{1.25h} \\v=59.2km/h$

Find a polynomial, which, when added to the polynomial 5x^2–3x–9, is equivalent to:

djyliett [7]

So you need to turn 5x^2 -3x -9 into 2x - 3.

Well first you need to take 5x^2 out by subtracting 5x^2 (-5x^2).

Then -3x needs to become 2x by adding 5x (+5x).

Finally -9 needs to become -3 by adding 6 (+6).

Put all the things you did together to make a polynomial.
-5x^2 + 5x + 6

According to the manufacturer of a backup UPS device, the normal output voltage is 120 volts. The sample of 40 measured voltage

anyanavicka [17]

Answer:

z = 1.83<1.96

null hypothesis is accepted

The sample is came from a population mean

Step-by-step explanation:

Step :-1

The sample of 40 measured voltage amounts from a unit have a mean of 123.59 volts and a standard deviation of 0.31 volts

given sample size n =40

mean of the sample ×⁻ = 123.59 volts

standard deviation of sample σ = 0.31 volts

Step2:-

Null hypothesis :-

the sample is from a population with a mean equal to 120 volts.

H₀ : μ =120

Alternative hypothesis:-

H₁ : μ ≠120

level of significance:- α =0.05

Step 3:-

The test statistic

$z = \frac{x_{-}-mean }{\frac{S.D}{\sqrt{n} } }$

substitute values and simplification

$z = \frac{123.59-120}{\frac{0.31}{\sqrt{40} } }$

on simplification we get the calculated value

z = 1.83

The tabulated value z =1.96 at 0.05 % level of significance

Conclusion:-

Calculated Z < The tabulated value z =1.96 at 0.05 % level of significance

so the null hypothesis is accepted

The sample is came from a population mean
