Paraphin [41]3 years ago

The correct answer is 3x+90=180

<em>Because you add the 2x and the x and you get 3x then there is a 90 degree angles so you add that and =180</em>

<em>Once you put it in the equation you can subtract 90 from 180 and you get 90 which you then divided by 3x and x equals 30</em>

『Fast Please!』
GalinKa [24]
Examples - Measurements in cooking; Metric measurements (7 1/4”); Distance (9 1/2 miles)

Real-World Problem - You’re baking and need to triple a recipe. The recipe calls for 3 3/4 cups flour (per recipe). You’d need to triple that amount to make how much you’re looking to make. (3 x 3 3/4 = 11 1/4 cups flour)

Solve.<br> −8.5d ≥ 20<br><br> d ≤ –170<br> d ≥ –170
saw5 [17]

Answer:

\rm =>D \leqslant 2.352941

Step-by-step explanation:

−8.5d ≥ 20

Divide both sides by -8.5:

=> \cfrac {- 8.5 \: d}{  - 8.5} \ \geqslant  \cfrac{20}{ - 8.5}

\rm=>d \leqslant 2.352941

This is the answer.

An NBA fan named Mark claims that there are more fouls called on his team 1 point
inn [45]

Answer:

t=\frac{12.2-11.5}{\frac{1.6}{\sqrt{34}}}=2.551    

df = n-1=34-1=33

p_v =P(t_{(33)}>2.551)=0.008  

Since the p value is less than the significance level of 0.05 we have enough evidence to reject the null hypothesis in favor of the claim

And the best conclusion for this case would be:

b)The p-value is 0.008, indicating sufficient evidence for his claim.

Step-by-step explanation:

Information provided

\bar X=12.2 represent the sample mean fould against

s=1.6 represent the sample standard deviation

n=34 sample size  

represent the value that we want to test

\alpha=0.05 represent the significance level for the hypothesis test.  

t would represent the statistic (variable of interest)  

p_v represent the p value for the test (variable of interest)  

System of hypothesis

We need to conduct a hypothesis in order to check if the true mean is higher than 11.5 fouls per game:  

Null hypothesis:\mu \leq 11.5  

Alternative hypothesis:\mu > 11.5  

The statistic is given by:

t=\frac{\bar X-\mu_o}{\frac{s}{\sqrt{n}}}  (1)  

The statistic is given by:

t=\frac{12.2-11.5}{\frac{1.6}{\sqrt{34}}}=2.551    

P value

The degreed of freedom are given by:

df = n-1=34-1=33

Since is a one side test the p value would be:  

p_v =P(t_{(33)}>2.551)=0.008  

Since the p value is less than the significance level of 0.05 we have enough evidence to reject the null hypothesis in favor of the claim

And the best conclusion for this case would be:

b)The p-value is 0.008, indicating sufficient evidence for his claim.
