AURORKA [14]3 years ago

Answer:

1) -2/3(x+5)+4(x+5)-10/3(x+5)

=4(x+5)-10/3(x+5)-2/3(x+5)

=4(x+5)-(x+5)[10/3+2/3]

=4(x+5)-(x+5)(10+2/3)

=4(x+5)(12/3)(x+5)

=4(x+5)-4(x+5)

=0

So, Jada~ is ~correct, because ~ by ~adding~negative ~term~we ~get~the~same~value\\of~negative~term~ so, both ~are ~ equaled~ out ~ and ~ get~ 0

<u>-------------------------</u>

hope it helps...

have a great day!!

yanalaym [24]

Answer:It's an arithmetic sequence with a common difference, d, = 4

A1 = 8

A2 = 8+4 = 12

A3 = 12+4 = 16   = 8+4(3-1) = 8+4(2) = 8+8

AN = A1 + d(N-1)

AN = 8 +4(N-1)  =  the Nth term in the sequence

Step-by-step explanation: hoped it helped

Find the 64th term of the arithmetic sequence -4, -21, -38, ...−4,−21,−38,
lisov135 [29]

a_{n} = a_{1} + d(n - 1)  ; a₁ is the first term, d is the difference between terms, and n is the term

-4, -21, -38, ...   ⇒   a₁ = -4, d = -17

a_{n} = -4 - 17(n - 1)

   = -4 - 17n + 17

   = 13 - 17n

a_{64} = 13 - 17(64)

    = 13 - 1088

    = 1075

Answer: 1075

ind the value of the test statistic z using z equals StartFraction ModifyingAbove p with caret minus p Over StartRoot StartFract
Sergeeva-Olga [200]

Answer:

z=\frac{0.262 -0.25}{\sqrt{\frac{0.25(1-0.25)}{530}}}=0.638  

Step-by-step explanation:

Data given and notation

n=530 represent the random sample taken

X=139 represent the yellow pods in the random sample

\hat p=\frac{139}{530}=0.262 estimated proportion of yellow pods

p_o=0.25 is the value that we want to test

\alpha represent the significance level

z would represent the statistic (variable of interest)

p_v represent the p value (variable of interest)  

Concepts and formulas to use  

We need to conduct a hypothesis in order to test the claim that the true proportion is 0.25 or 25%:  

Null hypothesis:p=0.25  

Alternative hypothesis:p \neq 0.25  

When we conduct a proportion test we need to use the z statistic, and the is given by:  

z=\frac{\hat p -p_o}{\sqrt{\frac{p_o (1-p_o)}{n}}} (1)  

The One-Sample Proportion Test is used to assess whether a population proportion \hat p is significantly different from a hypothesized value p_o.

Calculate the statistic  

Since we have all the info requires we can replace in formula (1) like this:  

z=\frac{0.262 -0.25}{\sqrt{\frac{0.25(1-0.25)}{530}}}=0.638
