alisha [4.7K]4 years ago
6 0

Answer:

y = 3/2 , x = 3/2

Step-by-step explanation:

Solve the following system:

{x + y = 3 | (equation 1)

10 x = 15 | (equation 2)

Divide equation 2 by 5:

{y + x = 3 | (equation 1)

0 y+2 x = 3 | (equation 2)

Divide equation 2 by 2:

{y + x = 3 | (equation 1)

0 y+x = 3/2 | (equation 2)

Subtract equation 2 from equation 1:

{y+0 x = 3/2 | (equation 1)

0 y+x = 3/2 | (equation 2)

Collect results:

Answer: {y = 3/2 , x = 3/2

Vector A⃗ has magnitude 5.1 m and points to the right; vector B⃗ has magnitude 4.0 m and points vertically upward. What is the m
Doss [256]

The magnitude of the vector C that satisfies the expression is 6.48m

Given the following magnitude;

Vector A = 5.1m

Vector B = 4.0m (upward)

Taking the resultant vector of A and B we will have:

R=\sqrt{A^2+B^2}\\R=\sqrt{5.1^2+4.0^2}\\R=  \sqrt{26.01+16}\\R=\sqrt{42.01}\\R=  6.48m

Given the expression A⃗ +B⃗ +C⃗ =0⃗

R + C = 0

C = 0 - R

C = 0 - 6.48

C = -6.48m

Hence the magnitude of the vector C that satisfies the expression is 6.48m

Use technology to find the​ P-value for the hypothesis test described below.
Yakvenalex [24]

Answer:

The one tailed P-value for the test statistic for df = n-1 = 33-1 = 32 is

P-value=0.1575

Step-by-step explanation:

We are given:

t=1.021

n=33

Claim: \mu>98.6°F

Now we can use the technology like excel to find the P-value. The excel function is given below:

=TDIST(1.021,32,1)=0.1575

Where:

1.021 is the test statistic

32 is the degrees of freedom

1 stands for one tailed alternative hypothesis.

Therefore, the P-value is 0.1575

Can someone help me on this question please?
horsena [70]

Answer:

x = 140° ∵ allied angles sum to 180°

Step-by-step explanation:

Allied angles are interior angles within two parallel lines and they add up to 180°. In this case, x and 40° add up to 180° since there are two horizontal parallel lines.

Considering only functions with a greater rate of change than that of the function represented on the graph, which function has
MatroZZZ [7]

Answer:

Step-by-step explanation:

The rate of change is a just a fancy name for slope.

First let's calculate the slope of the line in the graph.

We see it passes through the points (3,2) and (0,-2), so the slope is:

S = \frac{2 - -2}{3 - 0} = \frac{4}{3}

So the reference slope is 4/3.

Next step is to identify, among the proposed solutions, the one that have a steepest slope than 4/3 (1.33).  In the equations, the slope is the coefficient of the x element.

A. 13/7 - Greater than 4/3?  Yes (1.86)

B. 7/5 - Greater than 4/3?  Yes (1.4)

C. 11/8 - Greater than 4/3?  Yes (1.375)

D. 5/4 - Greater than 4/3?  No (1.25)

E. 5/3 - Greater than 4/3?  Yes (1.66)

So, only D (5/4) is smaller than 4/3.  Among the 4 others, which one has the lowest slope?

11/8 has the lowest slope that is higher than 4/3.
