a Cone
15.1: Which Has a Larger Volume?
The cone and cylinder have the same height, and the
radii of their bases are equal.
Do you think the volume of the smaller one is more or
less than the volume of the larger one? Explain your
reasoning
8
8
Answer:
The cylinder has the larger volume. this is because the formula for the volume of a cone and cylinder are the same but the cone has the fraction 1/3.
So, three cones can fit into the cylinder, so it is less then one half

The green object below,is best defined as a ___ named____.
The green object below, is best defined as a Ray named AC.
In geometry, a ray is a part of a line that consists of a single initial point called the endpoint and extends infinitely in one direction. It can be thought of as a half-line, with one end point and the other end extending infinitely.
Rays are named using two points, with the endpoint being mentioned first.
Here, in the figure the green line has one point A and the next C and it is further extending.
Thus, the Green line is a Ray name as ray AC.

So the second problem 325 x 1 2/3 is greater then 325
and the third problem 325 x 1/4 is equal to 325The average daily volume of a computer stock in 2011 was million shares, according to a reliable source. A stock analyst believes that the stock volume in 2014 is different from the 2011 level. Based on a random sample of trading days in 2014, he finds the sample mean to be million shares, with a standard deviation of s million shares. Test the hypotheses by constructing a % confidence interval. Complete parts (a) through (c) below. (a) State the hypotheses for the test. : mu equals million shares : mu not equals million shares (b) Construct a % confidence interval about the sample mean of stocks traded in 2014. The lower bound is nothing million shares. The upper bound is nothing million shares. (Round to three decimal places as needed.) (c) Will the researcher reject the null hypothesis?
Complete question :
The average daily volume of a computer stock in 2011 was p = 35.1 million shares, according to a reliable source. A stock analyst believes that the stock volume in 2014 is different from the 2011 level. Based on a random sample of 40 trading days in 2014, he finds the sample mean to be 30.9 million shares, with a standard deviation of s = 11.8 million shares. Test the hypotheses by constructing a 95% confidence interval. Complete parts (a) through (c) below. State the hypotheses for the test. Construct a 95% confidence interval about the sample mean of stocks traded in 2014.
Answer:
H0 : μ = 35.1 ;
H1 : μ < 35.1 ;
(26.488 ; 35.312)
Step-by-step explanation:
The hypothesis :
H0 : μ = 35.1
H1 : μ < 35.1
The confidence interval :
Xbar ± Margin of error
Xbar = 30.9
Margin of Error = Zcritical * s/sqrt(n)
Zcritical at 95% = 1.96
Margin of Error = 1.96 * (11.8/sqrt(40))
Margin of Error = 4.412
Lower boundary :
30.9 - 4.412 = 26.488
Upper boundary :
30.9 + 4.412 = 35.312
Confidence interval = (26.488 ; 35.312)
Since the population mean value exists within the interval, the we fail to reject the Null.

Una pelota sale disparada desde el nivel del suelo, con una velocidad de 40 m/s y un ángulo de elevación de 50°. a) Calcule la altura máxima que alcanza la pelota
Respuesta:
Los 47.85m
Explicación paso a paso:
Altura máxima = u²sin²Ф / 2g
Dado
velocidad u = 40 m / s
Ф = 50 °
g = 9,81 m / s²
Sustituir'
H = 40²sin²50 / 2 (9,81)
H = 1600 (0,7660) ² / 19,62
H = 1600 (0,5868) /19,62
H = 938,8096 / 19,62
H = 47,85 m
Por lo tanto, la altura máxima es de 47,85 m.

Data set doesn't go to 17
Step-by-step explanation:
None of the numbers go to 17
Answer:
1st option. the data set doesn't GO to seventeen
Step-by-step explanation:
look at the number line. I always had trouble with this so I get where your coming from first, look at where the line is touching don't pay attention to the box yet because it's confusing the entire point of this line is to show you that there MAY have been 1 or two people who where at 0 for this data and 1 or two people who were at 15
the point here is that the bulk of the data was 11-14, but because there were less people down lower, the mean of the data is at 13, and the data is bigger (skewed) to the left.
making everything lekse true except for the first option.
Zane needs 20 yards of fencing to go around his rectangular yard. What are possible dimensions for Zane's yard? Select all that apply .
Answer:
1 yard by 9 yards
2 yards by 8 yards
3 yards by 7 yards
4 yards by 6 yards
Step-by-step explanation:
the perimeter of the rectangular yard needs to be 20 yards
Perimeter of a rectangle = 2 x ( length + width)
20 = 2 x ( length + width)
( length + width) = 20 /2
( length + width) = 10
The sum of the length and width should equal 10
Possible dimensions that would equal 10 are :
1 yard by 9 yards
2 yards by 8 yards
3 yards by 7 yards
4 yards by 6 yards
