Please help me with this its due in 15 minutes plus ill need help with more
Anestetic [448]

Answer:

171 Square Feet

Step-by-step explanation:

We first cut the figure up into smaller parts...

we then use the formula (L x W = A) to find the area

L = Lenth

W = Width

the first rectangle (1)...

15 x 5 = 75

the second figure (2)...

8 x 9 = 72

the third figure (3)...

6 x 4 = 24

now we have to add up all the values to find the area of the entire figure...

75 + 72 + 24 = 171

<em>Hope this helps! Please let me know if you need more help or think my answer is incorrect. Brainliest would be MUCH appreciated. Also remember to rate answers to help other students, While leaving thanks to answers that help you. Have a great day!</em>

Zarrin [17]
The probability that a normally distributed data with a mean of μ and a standard deviation of σ is less than a value x is given by:

P(X\ \textless \ x)=P\left(z\ \textless \  \frac{x-\mu}{\sigma} \right)

Given that μ = 16.5 and σ = 0.804984 and that the probability that the <span>mean​ oil-change time being at or below the sample mean for which there is an area of 0.10 to the left under the normal curve, then:

P\left(z\ \textless \  \frac{x-16.5}{0.804984} \right)=0.1\\  \\ \Rightarrow P\left(z\ \textless \  \frac{x-16.5}{0.804984} \right)=P(z\ \textless \ -1.281) \\  \\ \Rightarrow\frac{x-16.5}{0.804984}=-1.281 \\  \\ \Rightarrow x-16.5=-1.281(0.804984)=-1.031 \\  \\ x=-1.031+16.5=15.47</span>
