Answer:

each taco costs $8 and each soda $4

Step-by-step explanation:

the difference between the two is $16 and half of $16 is $8 so you can tell each taco is $8. That automatically shows that the rest of the cost is $8 which half of is $4

Answer:

The 98% confidence interval estimate of the mean is between 32.45 hg and 34.75 hg.

32.3 is not a part of the confidence interval, which means that yes, these results are very different from the confidence interval 32.3 hg​

Step-by-step explanation:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1 - 0.98}{2} = 0.01[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].

That is z with a pvalue of [tex]1 - 0.01 = 0.99[/tex], so Z = 2.327.

Now, find the margin of error M as such

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

[tex]M = 2.327\frac{6.2}{\sqrt{157}} = 1.15[/tex]

The lower end of the interval is the sample mean subtracted by M. So it is 33.6 - 1.15 = 32.45 hg

The upper end of the interval is the sample mean added to M. So it is 33.6 + 1.15 = 34.75 hg

The 98% confidence interval estimate of the mean is between 32.45 hg and 34.75 hg.

Are these results very different from the confidence interval 32.3 hg​

32.3 is not a part of the confidence interval, which means that yes, these results are very different from the confidence interval 32.3 hg​

Answer:

Slope, m = 7/2 or 3.5

Step-by-step explanation:

Given the following data;

Points on the x-axis (x1, x2) = (5, 9)

Points on the y-axis (y1, y2) = (-4, 10)

To find the slope;

Mathematically, slope is given by the formula;

[tex] Slope = \frac{Change \; in \; y \; axis}{Change \; in \; x \; axis} [/tex]

[tex] Slope, m = \frac {y_{2} - y_{1}}{x_{2} - x_{1}} [/tex]

Substituting into the equation, we have;

[tex] Slope, m = \frac {10 - (-4)}{9 - 5} [/tex]

[tex] Slope, m = \frac {10 + 4}{4} [/tex]

[tex] Slope, m = \frac {14}{4} [/tex]

Slope, m = 7/2 or 3.5

Answer:

So for the head and tails one it is 1/1 chance of getting a head and for the dice on it is 1/21 that's the porbability hopes this helps :)

Step-by-step explanation:

Probability of getting a head on the coin and a 4 on the die​ is 0.083.

Probability defines the likelihood of occurrence of an event. Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

Probability(Event) = Favorable Outcomes/Total Outcomes

According to the question

A coin is flipped and a die is rolled

Probability of getting a head on the coin and a 4 on the die​:

Total Number of favorable outcomes(coin is flipped) = {H, T}  = 2

Number of favorable outcomes (head) = 1

Total Number of favorable outcomes(die is rolled) = {1, 2, 3, 4, 5, 6}  = 6

Number of favorable outcomes (4 on the die) = 1

P(head) = [tex]\frac{1}{2}[/tex]

P(4) = [tex]\frac{1}{6}[/tex]

P(head and 4) = [tex]\frac{1}{2}[/tex]. [tex]\frac{1}{6}[/tex]

= [tex]\frac{1}{12}[/tex]

= 0.083

Hence, Probability of getting a head on the coin and a 4 on the die​ is 0.083.

Answer:

$400 and $1,000

Step-by-step explanation:

Let us assume the x be the amount invested in 7% account

And, 600 + x be the amount invested in 9% account

Now the equation is

7x% + 9%(600 + x) = $118

0.07x + 54 + 0.09x = $118

0.16x = $118 -$54

0.16x = $64

x = $400

And, the other one is = $400 + $600 = $1,000
