The mode is whichever one has the most so the mode would be 7. And the range is the highest number to the lowest. So 9-4 which is 5

Alabama papas must average 80 on five test . Scores on the first four test were 81 73 84 and 76 what is the lowest score she can

Salsk061 [2.6K]

She has to score at least 86 on her fifth test.

Further explanation:

We will use the average formula to find the fifth value.

Given

$Average\ required=80\\x_1=81\\x_2=73\\x_3=84\\x_4=76\\x_5=?$

We have to find x5

The formula for average is:

$x=\frac{Sum\ of\ values}{Total\ number\ of\ values}\\Here,\\n=5\\So,\\x=\frac{x_1+x_2+x_3+x_4+x_5}{5}\\Putting\ values\\80=\frac{81+73+84+76+x_5}{5}$

$80*5=314+x_5\\400=314+x_5\\x_5=400-314\\x_5=86$

She has to score at least 86 on her fifth test.

The distance from Neptune to Mars is 4.272\times 10^{9}4.272×10 9 kilometers. How long would it take a rocket, traveling at 4.8\

just olya [345]

The time taken is $8.9 * 10^4hrs

<h3>Distances</h3>

Given the following information:

Distance from Neptune to Mars = $4.272\times 10^{9}$
Time is taken = $4.8\times 10^{4}km/hr$

Get the time taken:

Time = Distance/Speed

Time = $\frac{4.272\times10^9}{4.8\times 10^4}$

Time = 0.89 * 10^5

Time = 8.9 * 10^4hrs

Hence the time taken is $8.9 * 10^4hrs

Solve 1/2cot(x)>=1/2 over 0<=x<=2pi

RSB [31]

9514 1404 393

Answer:

(0, π/4] ∪ (π, 5π/4]

Step-by-step explanation:

Multiplying by 2 gives ...

cot(x) ≥ 1

The cotangent function decreases from ∞ to 1 in the domain (0, π/4], and again in the domain (π, 5π/4]. The solution is the union of these two intervals.

x ∈ (0, π/4] ∪ (π, 5π/4]

_____

(a, b] is interval notation for a < x ≤ b
