Answer:

rhombus; Measure of angle B = 70 degrees

Step-by-step explanation:

The shape is a rhombus. Angle B and angle A are supplementary, so they add up to 180 degrees.

110 + B = 180

B = 180 - 110

B = 70

It is a rhombus because all sides are equal.

Friends go on a trip. Jeff drove 1/2 of the trip and Jason Joe 1/4 of the trip.Susan and Sharon divided the rest of the drive eq
IgorLugansk [536]

Answer:

21 miles

Step-by-step explanation:

Jeff drove =\dfrac{1}{2} of the trip

Jason Joe drove =\dfrac{1}{4} of the trip

Together Jeff and Jason Joe drove =\dfrac{1}{2}+\dfrac{1}{4}=\dfrac{2}{4}+\dfrac{1}{4}=\dfrac{3}{4} of the trip

All trip =1

Remaining trip =1-\dfrac{3}{4}=\dfrac{4}{4}-\dfrac{3}{4}=\dfrac{1}{4}

Susan and Sharon divided the rest of the drive equally, so

Susan drove = Sharon drove =\dfrac{1}{4}:2=\dfrac{1}{4}\cdot \dfrac{1}{2}=\dfrac{1}{8} of the trip.

The entire trip was 168 miles, then

Sharon drove =\dfrac{1}{8}\cdot 168=21\ miles

3/4 x 5 In decimal form
Harrizon [31]

Answer:

3/4x5=?

Step-by-step explanation:

Three quarters times five in decimal form is a really simple problem we will first start with the 3/4x5, as we know 3/4 is equivalent to 0.75 so we already have it in decimal form and we would then multiply, 0.75x5=3.75.

In conclusion 3/4x5 in decimal form is 3.75

snow_tiger [21]

Answer:

The interval estimate for the population proportion of American adults who got their health insurance from an employer is (0.43, 0.47).

Step-by-step explanation:

The confidence interval is the interval estimate of the population parameter.

The confidence interval has a certain probability that the true value of the parameter is contained in the interval.

The general form of the confidence interval is:

CI=SS\pm MOE

Here,

SS = sample statistic.

MOE = margin of error

The sample statistic is an unbiased estimator of the population parameter. If the sample size is large enough then the sample statistic can be used to estimate the population parameter value.

In this case the parameter of interest is the population proportion of American adults who got their health insurance from an employer.

The information provided is:

<em>SS = p = </em>0.45.

<em>MOE</em> = 0.02.

Compute the confidence interval for the population proportion <em>p</em> as follows:

CI=p\pm MOE\\=0.45\pm 0.02\\=(0.43, 0.47)

Thus, the interval estimate for the population proportion of American adults who got their health insurance from an employer is (0.43, 0.47).
