Answer:
64 times bigger
Step-by-step explanation:
I will use random values for this explanation to make it more understandable.
Lets say the length of the box is 1 inch, width is 1 inch, and height is 1 inch.
The volume would be l*w*h = 1*1*1 = 1 cubic inch
If the dimensions were 4 times bigger, the length, width and height would all be 4 inches.
4*4*4 = 64 cubic inches, which is 64 times bigger than the smaller box with a volume of 1 cubic inch.
Hope this answer helped! :)

What is the constant of proportionality in terms of the context? Show your work or explain how you determined your answer. What is the total amount of water, in gallons, in the pool after 47 minutes? Show your work or explain how you determined your answer.
When we multiply our servings by a given amount, we're not multiplying our cost of cake by the same amount. This tells us that this is not proportional. One way to think about proportional relationships, we already said, that the ratio between the variables will be equivalent.

A pair of roller skates is discounted by 40%. The normal price is $65. What is the discounted price?
Answer:$39
Step-by-step explanation:
The discounted price is going to be 60% of the original price because 100 - 40 = 60. So we want to find 60% of the original price, or 65. 65 x . 6 = 39, so the pair of rollerskates will be $39 at the discounted price.
I have no idea what this is.

Keisha, Boris, and Jose sent a total of 126 text messages over their cell phones during the weekend. Boris sent 4 times as many messages as Jose. Jose sent 6 fewer messages than Keisha. How many messages did they each send?
Answer:
Boris=504 keisha=120
Step-by-step explanation:
First you would start off by Multiplying 4x126 the result of that is= 504 so thats how much Boris sent. To get the answer to how many jose sent you simply just subtract 6-126 and that should result in 120

arcAE = 126°
Step-by-step explanation:
Note that arcAD is a diameter therefore arcAD = 180°. And arcAD = arcAE + arcED
Also note that the inscribed angleEAD intercepts the arcED and according to the inscribed angle theorem,
angleEAD = (1/2)arcED
or
arcED = 2×angleEAD = 2×(27°) = 54°
This means that the arcAE is
arcAE = arcAD - arcED
= 180° - 54°
= 126°
[tex]\\ \sf\longmapsto arc \overset{\sim}{ED}=2(<A)=2(27)=54°[/tex]
Now
[tex]\\ \sf\longmapsto arc\overset{\sim}{AE}+arc\overset{\sim}{ED}=180[/tex]
[tex]\\ \sf\longmapsto arcc\overset{\sim}{AE}=180-54=126°[/tex]

Answer:
25%
Step-by-step explanation:
The mean for a data set is 60. The Z-score for
data point a is 0. The z-score for data point b
is -0.4. Which are the possible values for data
point a and b?
A. a = 0 and b = 61.2
B. a = 0 and b = 58.8
C. a = 60 and b = 61.2
D. a = 60 and b = 58.8
Answer:
D. a = 60 and b = 58.8
Step-by-step explanation:
Z-score:
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Z-score for data point a is 0.
This means that a is the mean, that is, a = 60.
The z-score for data point b is -0.4.
This means that b must be a value below the mean, that is, a value below 60.
The option that satisfies a = 60 and b < 60 is option D, which is the answer.
A stock market analyst notices that in a certain year, the price of IBM stock increased on 131 out of 252 trading days. Can these data be used to find a 95% confidence interval for the proportion of days that IBM stock increases
Answer:
95% confidence interval for the proportion of days that IBM stock increases.
(0.45814 , 0.58146)
Step-by-step explanation:
Step:1
Given that a stock market analyst notices that in a certain year, the price of IBM stock increased on 131 out of 252 trading days.
Given that the sample proportion
[tex]p^{-} = \frac{131}{252} = 0.5198[/tex]
Level of significance = 0.05
Z₀.₀₅ = 1.96
Step:2
95% confidence interval for the proportion of days that IBM stock increases.
[tex](p^{-} - Z_{0.05} \frac{\sqrt{p(1-p)} }{\sqrt{n} } , p^{-} + Z_{0.05} \frac{\sqrt{p(1-p)} }{\sqrt{n} } )[/tex]
[tex](0.5198 - 1.96(\sqrt{\frac{0.5198(1-0.5198)}{252} } , 0.5198 +1.96(\sqrt{\frac{0.5198(1-0.5198)}{252} })[/tex]
(0.5198 - 0.06166 , 0.5198+0.06166)
(0.45814 , 0.58146)
Final answer:-
95% confidence interval for the proportion of days that IBM stock increases.
(0.45814 , 0.58146)

Answer:
A is the answer brainliest?
Step-by-step explanation:
A psychologist would like to examine the effect of fatigue on mental alertness. An attention test is prepared which requires subjects to sit in front of a blank TV screen and press a response button each time a dot appears on the screen. A total of 110 dots are presented during a 90-minute period, and the reach subject. Two groups of subjects are selected. The first group (n 5) is tested after they have been kept awake for 24 hours. The second group (n-10) is tested in the morning after a full night's sleep. The data for these two samples are as follows:
Awake 24 hours rested
x=35 X=24
ss=120 ss =360
On the basis of these data, can psychologist conclude that fatigue significantly increases errors on an attention task? Test with α-05 and report effect size.
Answer:
The calculated value of t= 0.1908 does not lie in the critical region t= 1.77 Therefore we accept our null hypothesis that fatigue does not significantly increase errors on an attention task at 0.05 significance level
Step-by-step explanation:
We formulate null and alternate hypotheses are
H0 : u1 < u2 against Ha: u1 ≥ u 2
Where u1 is the group tested after they were awake for 24 hours.
The Significance level alpha is chosen to be ∝ = 0.05
The critical region t ≥ t (0.05, 13) = 1.77
Degrees of freedom is calculated df = υ= n1+n2- 2= 5+10-2= 13
Here the difference between the sample means is x`1- x`2= 35-24= 11
The pooled estimate for the common variance σ² is
Sp² = 1/n1+n2 -2 [ ∑ (x1i - x1`)² + ∑ (x2j - x`2)²]
= 1/13 [ 120²+360²]
Sp = 105.25
The test statistic is
t = (x`1- x` ) /. Sp √1/n1 + 1/n2
t= 11/ 105.25 √1/5+ 1/10
t= 11/57.65
t= 0.1908
The calculated value of t= 0.1908 does not lie in the critical region t= 1.77 Therefore we accept our null hypothesis that fatigue does not significantly increase errors on an attention task at 0.05 significance level

Answer:
8) 42 in²
9) 33 cm²
10) 112 yd²
Step-by-step explanation:
8) The area is given by the formula ...
A = 1/2(b1 +b2)h
A = (1/2)(9 in +5 in)(6 in) = 42 in²
__
9) The area is half the product of the lengths of the diagonals.*
A = 1/2(d1)(d2)
A = 1/2(6 cm)(11 cm) = 33 cm²
__
10) As in the previous problem, ...
A = 1/2(14 yd)(16 yd) = 112 yd²
_____
* This formula works for any quadrilateral with perpendicular diagonals.
