3\frac{5}{8} + 1\frac{3}{4} = \frac{3*8 + 5}{8} + \frac{4+3}{4} = \frac{29}{8} + \frac{7}{4} = \frac{29+14}{8} (We take 8, which is the LCM of 4 and 8, as the common denominator) = \frac{43}{8}

A.
well, to find the perimeter of a rectangle, it is 2(length+width)
using this, the perimeter of the tennis court is 2(2x+6+x)=2(3x+6)=6x+12
the perimeter of the basketball court is 2(3x-14+1/2x+32)=2(2 1/2x+18)= 5x+36
B. 
the difference is subtraction, so it'd be 6x-12-(5x+36)
C.
width is 2x+6
2x+6=36
2x=30
x=15
tennis: 15 by 36
basketball: 3*15-14= 31
1/2*15+32= 39.5
31 by 39.5

Cloud [144]

Answer:

There is enough statistical evidence to say that the means are different.

Step-by-step explanation:

<em>The question is incomplete:</em>

<em>"The two-sample t statistic for comparing the population means has value (±0.001)."</em>

<em />

The null and alternative hypothesis are:

H_0: \mu_r-\mu_b=0\\\\H_1: \mu_r-\mu_b\neq0

The level of significance is assumed to be α=0.01.

The difference of the sample means is:

M_d=M_r-M_b=9.64-15.84=-6.20

The standard deviation for the difference of the means is:

s_d=\sqrt\frac{s_r^2+s_b^2}{n} } =\sqrt\frac{3.43^2+8.65^2}{21} }=\sqrt{\frac{85.59}{21} }=\sqrt{4.12} =2.03

Then, the t-statistic is:

t=\frac{M_d-(\mu_r-\mu_b)}{s_d} =\frac{-6.20-0}{2.03}= -3.05

The degrees of freedom are:

df=n_r+n_b-2=21+21-2=40

With 40 degrees of freedom the t-critial for a significance of α=0.01 is t=±2.705.

As the t-statistic lies in the rejection region, the effect is significant and the null hypothesis is rejected.

There is enough statistical evidence to say that the means are different.

Answer:

BQ = 16

QE = 8

Step-by-step explanation:

Centroid of a triangle divides the median in the ratio 2 : 1

Here, let BQ = 2x and QE = x

BQ + QE = BE

2x + x = 24

3x = 24

x = 24/3

x = 8

2x = 2*8 = 16

BQ = 16

QE = 8
