Good evening ,

<h3><u><em>Answer :</em></u></h3><h2>$60</h2>

<u><em></em></u>

<u><em>Step-by-step explanation:</em></u>

   p − p×(15/100) = 51

⇔ p(1 - 15/100) = 51

⇔ p×[(100-15)/100] = 51

⇔ p×(85/100) = 51

⇔ 85×p = 100×51

⇔ p = 51×(100÷85) = 5 100÷85 = 60.

valentina_108 [34]

Answer:

Yes, the value 1411.8 cm³ is significantly high.

Step-by-step explanation:

Consider the provided information.

The brain volumes ​(cm cubed​) of 20 brains have a mean of 1111.2 cm cubed and a standard deviation of 125.3 cm cubed.

The range rule of thumb to identify the limits separating values that are significantly low or significantly high is:

The range rule of thumb identifying significant values are as.

Significantly low values are μ-2σ

Substitute the μ = 1111.2 and σ = 125.3 in above formula.

1111.2-2(125.3)=860.6

Significantly high values are μ+2σ

Substitute the μ = 1111.2 and σ = 125.3 in above formula.

1111.2+2(125.3)=1361.8

The value is significantly high due to the value 1411.8 cm³ is not lie between the values 860.6 cm³ and 1361.8 cm³.

Hence, Yes, the value 1411.8 cm³ is significantly high.
