Answer : 90 in^2

Parallelogram is make of 4 triangles and each triangle is a right angle triangle

4 triangles are congruent (sides and angles are equal)

so we find area of one triangle and then multiply by 4 to get the area of whole figure

Area of one triangle = \frac{1}{2} * base * height

base = 7.5 in and height = 6 in

Area of one triangle = \frac{1}{2} * 7.5 * 6 = 22.5 square inches

Area of whole figure = 4 * 22.5 = 90 in^2

Find the product. x3(x2+5x+1)
Stella [2.4K]

Answer: x^5+5x^4+x^3


Step-by-step explanation:

assuming the expression is x^3(x^2+5x+1) each term in the bracket is multiplied by x^3

x^3(x^2+5x+1)

=(x^3*x^2)+(x^3*5x)+(x^3*1)

=x5+5x^4+x^3

The average expenditure on Valentine's Day was expected to be $100.89 (USA Today, February 13, 2006). Do male and female consume
AfilCa [17]

Answer:

Yes. The male and female consumers differ in the amounts they spend.

Step-by-step explanation:

We can express the null and alternative hypothesis as:

H_0: \mu_m=\mu_w\\\\H_1:  \mu_m\neq\mu_w

It is assumed a significance level of 0.05.

The standard deviation of the difference of means is calculated as:

s=\sqrt{\frac{s_m^2}{n_m} +\frac{s_w^2}{n_w} } =\sqrt{\frac{35^2}{40} +\frac{20^2}{30} } =\sqrt{30.625+13.333} =\sqrt{43.958} =6.63

The test statistic is

t=\frac{(M_m-M_w)-0}{s}=\frac{135.67-68.64}{6.63}=10.11

The degrees of freedom are:

df=n_1+n_2-2=40+30-2=68

The P-value for t=10.11 is P=0, so it is smaller than the significance level. The null hypothesis is rejected.

We can conclude that male and female consumers differ in the amounts they spend.
