She got 23 votes. Multiply the number of students that voted by the percentage, but turn the percent into a decimal. 50x.46=23.00

Each algorithm is applied to a group of 52 sample problems. The new algorithm completes the sample problems with a mean time of

dem82 [27]

Answer:

Therefore we fail to reject the Null hypothesis $H_0$

Because the is no sufficient evidence to support the claim of the alternative hypothesis $H_a$

Step-by-step explanation:

From the question we are told that

Sample size $n_1 =52$

Mean time 1 $\=x_1=24.04\ hours$

Mean time 2 $\=x_2=24.52\ hours$

Standard deviation $\partial _1=5.769$

Standard deviation $\partial _2=5.556$

Level of significance 0.05

The null hypothesis is $H_o: \mu_1=\mu_2$

Alternative hypothesis $H_a: \mu_1$

Generally the test statistics is mathematically represented as

$Z= \frac{\=x_1-\=x_2}{\sqrt{\frac{\sigma_1^2}{n_1}+\frac{\sigma_2^2}{n_2}}}$

$Z= \frac{24.04-24.52}{\sqrt{\frac{5.769^2}{52}+\frac{5.5562^2}{52}}}$

$Z= -0.4321583379$

$Z= -0.43$

From Table the Z-critical value at $\alpha =0.05\ is\ -1.6449$

Therefore

Zcal> Zcritical

(-0.43)=(-1.645)

Generally we fail to reject the null hypothesis $H_0$ at $\alpha = 0.05$

Therefore we fail to reject the $H_0$

Because the is no sufficient evidence to support the claim of $H_a$

Maria flipped a coin 60 times, and the coin came up tails 32 times. What is the relative frequency of the coin turning up heads

Blizzard [7]

60 -32 = 28

The coin landed on heads 28 times.

Relative frequency = heads/ total flips

28/60 = 0.4666666 ( the 6 keeps repeating)

Round the answer as needed.

What is the x-intercept of the graphed line?

nevsk [136]

Answer:

<h3><u>the x-intercept and y-intercept are both 0</u>. </h3><h3 />

Step-by-step explanation: explanation: the y intercept is where the line touches the y-axis (the vertical line in the middle) and the x-intercept is where the line touches the horizontal line (the x-axis) in this case the line is touching both at the same time. I which I help. Have a Nice Day ( and make sure to give me five stars) :)
