Answer:
8 ounce jar
Step-by-step explanation:
We divide the price by the number of ounces to find the unit rate or cost per one ounce.
2.79/8=0.34875
5.54/15=0.3693
The 8 ounce jar has the best unit rate with a lower cost per ounce.
Answer:
Contour lines
Step-by-step explanation:
A series of light brown lines drawn at intervals of 50 feet to designate their respective heights above sea level are called CONTOUR lines, or just contour.
A contour line (also called isoline) is a line that indicates points at the same elevation on the map, showing you a representation of the terrain's elevation (hills, mountains, canyons and so on). You will find those lines on specialized maps, like topographic maps, which are different than road maps.
Answer:
box 1: monomial
box 2: binomial
Step-by-step explanation:
reasoning: Box 1’s volume is modeled by a monomial times a monomial, so it will be a monomial.
Box 2’s volume is modeled by a monomial times a binomial, so it will be a binomial.
Answer:
Step-by-step explanation:
Hello!
To test if boys are better in math classes than girls two random samples were taken:
Sample 1
X₁: score of a boy in calculus
n₁= 15
X[bar]₁= 82.3%
S₁= 5.6%
Sample 2
X₂: Score in the calculus of a girl
n₂= 12
X[bar]₂= 81.2%
S₂= 6.7%
To estimate per CI the difference between the mean percentage that boys obtained in calculus and the mean percentage that girls obtained in calculus, you need that both variables of interest come from normal populations.
To be able to use a pooled variance t-test you have to also assume that the population variances, although unknown, are equal.
Then you can calculate the interval as:
[(X[bar]_1-X[bar_2) ± 
* 
]
[(82.3-81.2) ± 1.708* (6.11*
]
[-2.94; 5.14]
Using a 90% confidence level you'd expect the interval [-2.94; 5.14] to contain the true value of the difference between the average percentage obtained in calculus by boys and the average percentage obtained in calculus by girls.
I hope this helps!
Answer:
Equation 1
18 represents the number of tickets Zhi starts with. -3 is how many tickets each game uses, G is the amount of games played.
Equation 2
This equation is just equation 1 in factored form, 3 times 6= 18 and -g times 3= -3g. All of the parts are the same from the first equation.
Hope this helps some!!
