Taisha is making gift bags for birthday. She intends to fill each bag with ½ pound of chocolate. Her chocolate bag weighs 4 ¾ pounds. Taisha can make 9.5 gift bags for the birthday.
This is calculated as,
There are 4 ¾ pounds of chocolate.
Each bag will have ½ pound of chocolate.
½ pound × Gift bags = 4 ¾ pounds.
4 ¾ pounds ÷ ½ pound = Gift bags.
4 ¾ pounds is 4.75 pounds and ½ pound is 0.5 pounds.
4.75 pounds ÷ 0.5 pound = 9.5 bags.
Hence , Taisha could make 9.5 gift bags for the birthday.

Answer:
5 different triangles
Step-by-step explanation:
we know that
The number of diagonals of an n-sided polygon is given by the formula :
where
n is the number of sides
In this problem
n=5
substitute
see the attached figure to better understand the problem
The number of different triangles that can be formed by the sides of the polygon and its diagonals is equal to 5
so

A correlation coefficient between average temperature and coat sales exists most likely to be between 0 and -1.
<h3>What is the correlation coefficient?</h3>
The correlation coefficient exists as the exact measure that quantifies the power of the linear relationship between two variables in a correlation analysis. A correlation coefficient between average temperature and coat sales exists most likely to be between 0 and -1.
A negative correlation suggests two variables that tend to move in opposite directions. A correlation coefficient of -0.8 or lower displays a strong negative relationship, while a coefficient of -0.3 or lower signifies a very weak one.

The correct equations of a parabola are z = 2(y-9)²-2 and y = 2(z-2)²-9.
This is a problem with coordinate geometry. We can solve this by following a few steps.
First of all we should know the ideal equation of a parabola. The equation is,
- where ( h, k ) is the vertex of the parabola.
From all those options only last two equations satisfy the conditions.
Where the coordinate of the vertex of this parabola is ( 9, 2 ).
Hence we can conclude that z = 2(y-9)²-2 and y = 2(z-2)²-9 are the correct equation of a parabola.
