Answer:

The Standard Deviation

Step-by-step explanation:

Your concentration should be on what the standard deviation tells us about the data. The standard deviation is a number which measures how far the data are spread from the mean. Let a calculator or computer do the arithmetic. The standard deviation, s or σ , is either zero or larger than zero.

Find the length of rhombus whose diogonals are length 12 cm and 16 cm

grin007 [14]

In ΔAOD (AD) =(AO)

2+(OD)

2 =36+64 AD

2 =100

AD= 100

=10cm

Rhombus has all sides equal

AB = AD = BC = CD = 10 cm

The graph of a function f(x) is shown below: plot ordered pairs negative 1, negative 3 and 0, 1 and 1, 2.2 and 2, 3

JulijaS [17]

we have the points

$A(-1,-3)\\B(0,1)\\C(1,2.2)\\D(2,3)$

Using a graphing tool

see the attached figure

the domain is the interval---------> $[-1,2]$

$-1 \leq x\leq 2$

the range is the interval--------> $[-3,3]$

$-3 \leq y\leq 3$

therefore

<u>the answer is the option D</u>

integers from $-1 \leq x\leq 2$

Company A makes a large shipment to Company B. Company B can reject the shipment if they can conclude that the proportion of def

boyakko [2]

Answer:

$z=\frac{0.1475-0.1}{\sqrt{\frac{0.1(1-0.1)}{400}}}=3.17$

The p value for this case would be given by:

$p_v =P(z>3.17)=0.00076$

For this case the p value is lower than the significance level so then we have enough evidence to reject the null hypothesis and we can conclude that the true mean is significantly higher than 0.1 and then Company B can reject the shipment

Step-by-step explanation:

Information provided

n=400 represent the random sample taken

X=59 represent number of defectives from the company B

$\hat p=\frac{59}{400}=0.1475$ estimated proportion of defectives from the company B
