Answer:

10.2%

Step-by-step explanation:

Prediction of the broadcaster = 88 points

Actual score scored = 98points

% error = actual score-predicted score/actual score × 100℅

Substitute the given scores into the formula;

%error = 98-88/98 × 100

%error = 10/98 × 100

%error = 1000/98

%error = 10.2%

Hence the broadcaster percentage error is approximately 10.2%

Suppose that the sitting​ back-to-knee length for a group of adults has a normal distribution with a mean of mu equals 22.1 in.
nadya68 [22]

Answer:

Step-by-step explanation:

Given that  the sitting​ back-to-knee length for a group of adults has a normal distribution with a mean of mu equals 22.1 in. and a standard deviation of sigma equals 1.2 in.

We have to find values of x such that

P(X\geq a) \leq 0.01\\ and

P(X\leq b) \leq 0.01

a=2.33 and b =-2.33 as z values

Let us convert to X values

x=22.1-2.33(1.2) \\x=22.1+2.33(1.2)\\

i.e. values below 19.304 and above 25.496

Hence for x below 19.304 and above 25.496 are significantly low and high.

24.2 length is not significantly high.

Jasmine purchased a laptop worth $1,500 in 2007. It loses its value by %32 each year. What is the value of the laptop in 2010? R
Lunna [17]

Answer:

$471.65

Step-by-step explanation:

-The value of the laptop after each year is calculated by the formula:

P_t=P_o(1-d)^t

where:

P_t is the value at time t

P_o is the initial value

d is the rate of depreciation

t is the time

#We substitute the values to solve for the value after 3 years(2010-2007=3):

P_t=P_o(1-d)^t\\\\=1500(1-0.32)^3\\\\=\$471.65

Hence, the value of the laptop in 2010 is $471.65

What is the simplest form of x^2+5X-36/x^2-16<br> X+9/X+4<br> 9/4<br> X+9/X-4<br> -9/4
Digiron [165]

Answer:

\frac{ {x}  + 9}{x - 4}

Step-by-step explanation:

\frac{ {x}^{2}  + 5x - 36}{ {x}^{2}  - 16}  \\  \\  = \frac{ {x}^{2}  + 9x  - 4x- 36}{ {x}^{2}  -  {(4)}^{2} } \\  \\  = \frac{ x({x}  + 9)  - 4(x + 9)}{ (x + 4)(x - 4) }  \\  \\  = \frac{ ({x}  + 9) \cancel{(x  - 4)}}{  \cancel{(x + 4)}(x - 4) } \\  \\  = \frac{ {x}  + 9}{x - 4}

7 x 5e = 105 <br><br><br>plz help ​
Anon25 [30]

e=3.

So this is how I approached this. Since 7 is being multiplied, I divided both sides by 7 so 105/7 = 15. Then it becomes simple as 5e=15. We divide both sides by 5 and get e=3. Tip: just try isolating the variable and then life is much easier.
