What is 7 4/5 rounded to the nearest whole

2 answers:

5 0

It would be 8 because 4 is closer to 5 than it is to zero, therefore it would round to a whole # which would be 1. Then you would add the one to your whole #.

The number of cases of a new disease can be modeled by the quadratic regression equation y = -2x^2 + 40x + 8. What is the best p

Stels [109]

Answer:

158 cases

Step-by-step explanation:

Given tbe quadratic regression model :

y = -2x^2 + 40x + 8

y = number of cases of a new disease

x = number of years

The predicted number of cases of a new disease in 15 years can be calculated thus ;

Put x = 15 in the equation ;

y = -2(15)^2 + 40(15) + 8

y = - 2 * 225 + 600 + 8

y = - 450 + 600 + 8

y = 158

158 cases

kkurt [141]

The area of the triangular sign is 36 square inches, if Gabrielle is cutting a triangular sign with a base of 8 inches and the perpendicular distance from the base of the sign to its vertex is 9 inches.

Step-by-step explanation:

The given is,

Gabrielle is cutting a triangular sign

Base of 8 inches

The perpendicular distance from the base of the sign to its vertex is 9 inches

Step:1

Formula for area of triangle is,

Area, $A = \frac{bh}{2}$ .....................................(1)

Where, b - Base of triangle

h - Height of triangle

From given value,

b - 8 inches

h - 9

Equation (1) becomes,

$A = \frac{(8)(9)}{2}$

$=\frac{72}{2}$

= 36

Area of triangle sign, A = 36 square inches

Result:

8 0
