The answer would be J because as the mothers shoe size gets larger, so does the weight of the baby, so there’s an increasing trend on the chart

The answer is J because most of the dots are going in an upward and forward line that mean that the more the babies weigh, the larger the mothers' shoe sizes are.

Vesnalui [34]

Answer:

1340 mL

Step-by-step explanation:

There are ...

2 + 3/4 + 1.5 + 1.25 = 5.5

cups of ingredients, and ...

1/2 + 1/2 + 3 = 4

teaspoons of ingredients. Each teaspoon is 1/3 of 1/16 of a cup, so is 1/48 of a cup.

Altogether, the volume of ingredients is ...

5.5 + 4/48 cups = 5 7/12 cups

= (5 7/12)×(240 mL/cup) = 1340 mL

Mei is standing next to a statue in the park. If Mei is 5 feet tall, her shadow is 3 feet long, and the statues shadow is 10 1/2

alisha [4.7K]

The problem presented above is an example in which we can use the concept of ratio and proportion. The ratio between the heights of Mei and the statue should be the same to the ratio of their shadows. Letting x be the height of the statue.
5 ft/ x ft = 3 ft / 10.5 ft
The value of x from the equation above is 17.5 ft.

Two researchers conducted a study in which two groups of students were asked to answer 42 trivia questions from a board game. Th

Answer:

(1) Correct option is B.

(2) Correct option is C.

Step-by-step explanation:

The information provided is:

$n_{1}=200,\ \bar x_{1}=22.7,\ s_{1} = 4.5\\n_{2}=200,\ \bar x_{2}=19.7,\ s_{2} = 4.3$

The (1 - <em>α</em>)% confidence interval for the difference between two mean is:

$CI=\bar x_{1}-\bar x_{2}\pm t_{\alpha/2, (n_{1}+n_[2}-2}\sqrt{\frac{s_{1}^{2}}{n_{1}}+\frac{s_{2}^{2}}{n_{2}} }$

The critical value of <em>t</em> is:

$\alpha /2=0.05/2=0.025$

degrees of freedom $=n_{1}+n_{2}-2=200+200-2=398$

$t_{\alpha/2, n_{1}+n_{2}-2}=t_{0.025, 398}=1.96$

Compute the 95% confidence interval for the difference between two mean as follows:

$CI=22.7-19.7\pm 1.96\sqrt{\frac{4.5^{2}}{200}+\frac{4.3^{2}}{200} }\\=3\pm0.8624\\=(2.1376, 3.8624)\\\approx(2.14, 3.86)$

Thus, the 95% confidence interval, (2.14, 3.86) implies that the true mean difference value is contained in this interval with probability 0.95.

Correct option is B.

The null value of the difference between means is 0.

As the value 0 is not in the interval this implies that there is a difference between the two means, concluding that priming does have an effect on scores.

Correct option is C.
