Answer:

a. p(x<= 5) = .15 + .4 + .25 = .8

C. .4(4.2) = 1.68

5.4(1-.4) = 3.24

3.24 + 1.68 = 4.92 ,, 4.92 > 4.55 so short is better

jarptica [38.1K]

Answer:the total discounted price for two dogs to be groomed is 22.75

Step-by-step explanation:

A dog groomer is offering 20% off a full groom for one dog, and 15% off for each additional dog. Normally, a full groom costs $65 for each dog.

If you decide to take your two furry friends to be groomed,

the discount on the first one would be

20/100 × 65 = 0.2 × 65 = 13

the discount on the second one would be

10/100 × 65 = 0.15 × 65 = 9.75

the total discounted price for two dogs to be groomed would be

13 + 9.75 = 22.75

A photo album contains small and large photographs. Each large photograph has side lengths that are twice the side lengths of ea
White raven [17]
Let
x----------> length side large <span>photograph
</span>y----------> width side large photograph and small photograph

<span>Each large photograph has side lengths that are twice the side lengths of each small photograph
</span>so
x/2--------> length side small photograph

we know that
The area of each small photograph is 24 in²
24=(x/2)*y------>24=x*y/2----->  48=x*y

The area of each large photograph is-----> x*y
therefore
The area of each large photograph is 48 in²

the answer is
48 in²

Austin keeps a right conical basin for the birds in his garden as represented in the diagram. The basin is 40 centimeters deep,
Alenkinab [10]

Answer:

51.15 cm

Step-by-step explanation:

Data provided

Basin = 40 centimeters deep

The Angle between the sloping sides = 77°

The calculation of the shortest distance between the tip of the cone and its rim is shown below:-

The angle will get divided and the angle is as follows

\frac{77^\circ}{2}=38.5^\circ

Here In the first triangle, we will follow "Cosine formula" which follows:-

\cos 38.5^\circ=\frac{Base}{Hypotenuse}

cos 38.5^\circ=\frac{40}{Hypotenuse}

\\\\0.782=\frac{40}{Hypotenuse}

\\\\Hypotenuse=\frac{40}{0.782}

=51.15\ cm
