hello :<span>
<span>the parabola's equation is : f(x) = a(x-5)²-5
the coefficient of the squared expression in the parabola's equation is : a
but ; f(6) = - 1
- 1 = a(6-5)²+5
a+5=-1.....a=-6
f(x) = -6(x-5)²+5</span></span>

<span><span>so : a = - 6</span></span>

Solve for x in the figure below
Ksju [112]
Since angles A and C are equivalent, then angles B and D must also be equivalent. So if
angle B = angle D then...

7x + 15 = 8x

Now we just solve for x

7x + 15 = 8x
15 = 8x - 7x
15 = x

We Can check to see if it is correct by substituting 15 in for x in the equation..

7x + 15 = 8x
7 (15)+15 = 8 (15)
105 +15 = 120
120 = 120

It checks! angles B and D = 120 degrees

Answer:

B. y ≤ –3x + 5

Step-by-step explanation:

Its B, all y-values are less than -3x+5. also consider root by setting -3x+5=0

x=5/3 is positive so its the second one

...................................................................................................................................................

Answer:

Step-by-step explanation:

we know that

The solution of the inequality is the shaded area below the solid line (the gray area)

The slope of the solid line is negative

The y-intercept of the solid line is positive

The equation of the solid line is equal to  

therefore

the equation of the inequality is equal to

A well-known brokerage firm executive claimed that 50% of investors are currently confident of meeting their investment goals. A
VMariaS [17]

Answer:

p_v =P(Z  

If we compare the p value obtained and using the significance level given \alpha=0.005 we have p_v so we can conclude that we have enough evidence to reject the null hypothesis, and we can said that at 5% of significance the proportion of adults that said they are confident of meeting their goals  is significantly lower than 0.5 or 50% .  

Step-by-step explanation:

1) Data given and notation

n=200 represent the random sample taken

X represent the people that said they are confident of meeting their goals

\hat p=0.44 estimated proportion of adults that said they are confident of meeting their goals

p_o=0.5 is the value that we want to test

\alpha=0.005 represent the significance level

Confidence=99.5% or 0.995

z would represent the statistic (variable of interest)

p_v represent the p value (variable of interest)  

2) Concepts and formulas to use  

We need to conduct a hypothesis in order to test the claim that the proportion is less than 0.5.:  

Null hypothesis:p\geq 0.5  

Alternative hypothesis:p < 0.5  

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.

3) Calculate the statistic  

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

z=\frac{0.44 -0.5}{\sqrt{\frac{0.5(1-0.5)}{200}}}=-1.697  

4) Statistical decision  

It's important to refresh the p value method or p value approach . "This method is about determining "likely" or "unlikely" by determining the probability assuming the null hypothesis were true of observing a more extreme test statistic in the direction of the alternative hypothesis than the one observed". Or in other words is just a method to have an statistical decision to fail to reject or reject the null hypothesis.  

The significance level provided \alpha=0.005. The next step would be calculate the p value for this test.  

Since is left tailed test the p value would be:  

p_v =P(Z  

If we compare the p value obtained and using the significance level given \alpha=0.005 we have p_v so we can conclude that we have enough evidence to reject the null hypothesis, and we can said that at 5% of significance the proportion of adults that said they are confident of meeting their goals  is significantly lower than 0.5 or 50% .
