1 answer:
ValentinkaMS [17]3 years ago
4 0

Answer:

B is the correct answer

Step-by-step explanation:

  1. Subtract area of triangle from total area: 30 - 14 = 16
  2. Since the figure is a square, all the sides are equal. Therefore, we need to find the square root of 16: √16 = 4
  3. All the sides of the square are 4 cm long

  1. To check, reverse application:
  2. 4 x 4 = 16
  3. 16 + 14 = 30

Rory is playing a video game where each game lasts 1 3/4 hours he wants to play for 9 hours today and evening how many games can
sesenic [268]

Answer: He will play 5 games in 9 hours .

Explanation:

In 1\frac{3}{4}\text hours , he is playing 1 game

So, in 1 hour , he will play = \frac{4}{7} games

In 9 hours, he will play

 =\frac{4}{7}\times 9\\=\frac{4\times9}{7}\\=5.14

Number of games can't be in decimals it must be in integers so we will take 5 only .

so he will play only 5 games in 9 hours .

Hi can some please help?
Oduvanchick [21]
So I'm assuming that you're taking Calculus.
The first thing you want to do is take the integral of f(x)...
Use the power rule to get:
4X^2-13X+3.
Now solve for X when f(x)=0. This is because when the slope is 0, it is either a minimum or a maximum(I'm assuming you know this)
Now you get X=0.25 and X=3. Since we are working in the interval of (1,4), we can ignore 0.25
Thus our potential X values for max and min are X=1,X=4,X=3(You don't want to forget the ends of the bounds!)
Plugging these value in for f(x), we get
f(1)=2.833
f(3)=-8.5
f(4)=1.667
Thus X=1 is the max and X=3 is the min.
So max:(1,2.833)
min:(3,-8.5)

Hope this helps!

Alpha false and true Which of the following statements are true? If false, explain briefly.
solmaris [256]

Answer:

A. False

B. True

C. True

D.True

Step-by-step explanation:

A. False . The significance level or alpha is the probability of rejecting the null hypothesis when it is true. For example, a significance level of 0.05 indicates a 5% risk of concluding that a difference exists when there is no actual difference. 0.01 alpha is better than 0.05 alpha . 0.01 indicate a 1% risk of rejecting the null hypothesis when it is true .

B. True . If the p-value is less than alpha, we reject the null hypothesis . Therefore statistically significant.

C . True . If the p-value is less than alpha, we reject the null hypothesis

D. True . Alpha will be greater than p-value . Therefore we will reject .

Evaluate triple integral ∫ ∫ ∫ 8xydV, where E lies under the plane z = 1+x+y and above the E region in the xy-plane bounded by t
vazorg [7]

Answer:

\mathbf{=\dfrac{163.384}{15}}

Step-by-step explanation:

\int \int \limits_{E} \int \ 8 xy dV = \int\limits^{1}_{0} \int\limits^{\sqrt{x}}_{0} \int\limits^{1+x+y}_{0} \ 8xy dz dydx

= \int\limits^{1}_{0} \int\limits^{\sqrt{x}}_{0} [ 8xyz]^{z=1+x+y}_{z=0}  \   \ dy dx

= \int\limits^{1}_{0} \int\limits^{\sqrt{x}}_{0} 8xy (1+x+y) dy dx

= \int\limits^{1}_{0} \int\limits^{\sqrt{x}}_{0} 8xy+8x^2y+8xy^2 \ \ dy dx

= \int\limits^{1}_{0}  \ [ 4xy^2+4x^2y^2+2.7xy^3]^{ y= \sqrt{x}}_{y-0} \ \  dx

= \int\limits^{1}_{0} \   4x (\sqrt{x})^2+4x^2(\sqrt{x})^2+2.7x(\sqrt{x})^3\ \  dx

= \int\limits^{1}_{0} \   4x^2+4x^3+2.7x^{5/2} \  dx

\mathbf{=\dfrac{163.384}{15}}
