I just added the two numbers and got the number 100.88

The 24.3 translates to 24.30, to match the two decimals of 76.58, then you align them
24.30
76.58
Add the column on the very right: 0 + 8 = 8 ; then the one on the left 3 + 5 = 8; then the next one 4 + 6 = 10; and the one at the very left 2 + 7 = 9 but we add the 1 of the last 10, and leave the 0 on the place, so it's 10
24.30
76.58
---------
100.88
You bring the point down two numbers from right to left, like in the numbers we are adding

A manufacturer of chocolate chips would like to know whether its bag filling machine works correctly at the 404 gram setting. It

Nezavi [6.7K]

Answer:

There is no sufficient evidence to support the claim that the bags are underfilled

Step-by-step explanation:

We are given;

n = 27 bags

Sample mean;X = 402 gram

Population mean;μ = 404 gram

Variance = 676

We know that, standard deviation(σ) = √variance

Thus;

σ = √676

σ = 26

The hypotheses are;

Null hypothesis; H0: μ = 404

Alternative hypothesis; HA: μ < 404

Let's find the z-score from the formula;

z = (X - μ)/(√σ/n)

z = (402 - 404)/√(26/27)

z = -2.04

From the z-distribution table attached, we have a p-value of 0.02068

This is less than the significance value of 0.01 and thus we will reject the null hypothesis and conclude that there is no sufficient evidence to support the claim that the bags are underfilled

Determine the intercepts of the line.<br> 71 - 5 = 4y - 6

maw [93]

Answer:

y = 18

Step-by-step explanation:

71 - 5 = 4y - 6

66 = 4y - 6

72 = 4y

18 = y

P.S. I am not 100% sure if this is correct if it isn't I am greatly sorry

25 POINTS!!! The equation y=470x represents the relationship between x, the time that a plane flies in hours, and y, the distanc

sineoko [7]

Answer:

Step-by-step explanation:

For plane A,

Equation that represents the relationship between time 'x' and distance 'y' is,

y = 470x

By comparing this equation with the slope-intercept form of the equation,

y = mx + b

m = slope = 470

b = 0

Here, slope represents the speed of plane A.

Therefore, speed of plane A = 470 mi per hour

For plane B,

From the given table,

Slope of the graph = $\frac{y_2-y_1}{x_2-x_1}$

= $\frac{960-480}{2-1}$

= 480

Speed of plane B = 480 miles per hour

Since, speed of plane B is more than plane A,

Plane B is flying faster.
